Apple adds WebM video playback support to Safari with macOS Big Sur 11.3

Avatar for Filipe Espósito

9to5Mac reported that Apple is now letting developers create extensions that modify some of the default Safari tabs with macOS Big Sur 11.3 beta, and it seems there’s more to come. With the release of macOS Big Sur 11.3 beta 2 this week, Safari can finally play WebM videos.

As noted by The 8-Bit , WebM video compatibility has been added to Safari with macOS Big Sur 11.3 beta 2. For those unfamiliar with the format, WebM is a royalty-free video codec created by Google in 2010 — similar to the WebP image format, also developed by Google.

Although nearly all current web browsers support WebP video, Apple has never added WebP support to Safari. Back in 2010, Steve Jobs argued that the WebM format was “a mess” and that Apple had no plans to adopt the codec. The company has always given preference to H.264 and H.265 codecs, which are not royalty-free but are widely used by popular streaming services .

If you’re running macOS Big Sur 11.3 beta 2 on your Mac, you can try playing a WebM video by going to the WebM Project website , which has a demonstration video available there.

Prior to that, Apple also added support for the WebP image format to Safari with macOS Big Sur, not to mention support for VP9 videos — which enabled 4K HDR videos on websites like YouTube and Netflix. Safari also gained other important features with Big Sur, including a built-in translator and more privacy controls.

macOS Big Sur 11.3 beta is currently available for developers and users registered in the Apple Beta Software Program. Apple hasn’t announced when the update will be available to the public.

iOS 15 will add WebM audio codec support to Safari

Earlier today, Apple seeded the fifth developer beta of iOS 15 . The newest version of the prerelease software didn’t add a whole lot to the mix, especially no major features, but there were some new additions. We’ve already rounded up what’s new , but there’s a bit more, apparently.

As first noted by  9to5Mac today, it appears that Apple will be making a subtle change to Safari once the newest version of iOS launches later this year by adding support for the WebM audio codec. The publication notes that it appears it’s an experimental feature, and it can be enabled or disabled right now in the beta of iOS 15 within Safari’s Settings. The internal code for iOS 15’s latest beta suggests it will be enabled by default once the software launches to the public, though.

WebM is an audio codec that’s part of the open media file format that Google created way back in 2010. There are a variety of different codecs, including the WebM video and WebP image extension. As noted in the original report, Steve Jobs, Apple’s co-founder, was never a fan of Google’s codecs, and Apple pushed back against them in general for years.

webm extension safari

It was only with the wide release of iOS 14 and macOS Big Sur that Apple added support for the WebP image extension in Safari. Meanwhile, Safari on macOS supports the WebM video codec, but it’s not available in the mobile version of Safari. That may be a matter of time, though.

With Apple adding support for the WebM audio codec, this may be a sign that the mobile version of Safari could gain support for the WebM video codec in the near future as well.

Apple adds WebM Web Audio support to Safari in latest iOS 15 beta

AppleInsider Staff's Avatar

Last updated 3 years ago

Currently available as an option in the Experimental WebKit Features section of Safari's advanced settings, WebM Web Audio and the related WebM MSE parser are two parts of the wider WebM audiovisual media file format developed by Google.

An open-source initiative, WebM presents a royalty-free alternative to common web video streaming technology and serves as a container for the VP8 and VP9 video codecs. As it relates to Safari, WebM Web Audio provides support for the Vorbis and Opus audio codecs.

Code uncovered by 9to5Mac reveals the WebM audio codec should be enabled by default going forward, suggesting that Apple will officially adopt the standard when iOS 15 sees release.

Apple added support for the WebM video codec on Mac when a second macOS Big Sur 11.3 beta was issued in February . The video portion of WebM has yet to see implementation on iOS, but that could soon change with the adoption of WebM's audio assets.

WebM dates back to 2010, but Apple has been reluctant to bake the format into its flagship operating systems. Late co-founder Steve Jobs once called the format "a mess" that "wasn't ready for prime time."

As AppleInsider noted when WebM hit macOS, Apple might be angling to support high-resolution playback from certain streaming services like YouTube, which rely on VP9 to stream 4K content. The validation of WebM Web Audio is a step in that direction.

Apple is expected to launch iOS 15 this fall alongside a slate of new iPhone and Apple Watch models.

Playback doesn't seem to be working yet in latest beta even though there is the option in settings. 

AppleInsider said: WebM dates back to 2010, but Apple has been reluctant to bake the format into its flagship operating systems. Late co-founder Steve Jobs once called the format "a mess" that "wasn't ready for prime time." It was a mess at the time given the potential for patent infringement.  That was settled a while ago, but Apple (and the rest of the industry) already had H.264.  So no real reason to add support until something required it.

Thanks for the insight @auxio. Now I wonder... what would require support for WebM audio?

https://www.ionos.com/digitalguide/websites/website-creation/webm/ WebM is open-sourced, no cost, easier to deploy, and mobile device friendlier. On the other hand H.264 and H.265 licensing has become a bit of a mystery, lots of questions about whether licensed integrators actually have full rights to use it, and quite the turnabout from a few years ago when MPEG LA pushed the story that it was Google and VP-9 with the problem. "Many multi-channel video providers say a major cause of the delay in deployments is that there are currently three patent pools representing different companies, making royalties difficult to understand. These organizations include  MPEG LA  (which includes Apple, Canon, JVC Kenwood, and Samsung..." Plus another separate pool claiming ownership:   " HEVC Advance  (including Dolby Labs Mitsubishi Electric Corp., Samsung Electronics, and Warner Bros. Entertainment)" and yet a THIRD: " Velos Media  (including Ericsson, Panasonic, Qualcomm, Sharp and Sony)  Ericsson ,  Panasonic ,  Qualcomm , Sharp and  Sony ). https://www.thebroadcastbridge.com/content/entry/11204/to-deploy-hevc-users-must-choose-what-patent-pool-to-dive-into Way too many fingers and dollars and restrictions, making WebM a far more simple solution with no real downsides other than support which is fast spreading.

YouTube Music probably.  Maybe not "require", but I bet Google prefers it, and maybe only offers higher bitrates in WebM, similar to how YouTube (video) was previously resolution limited unless using WebM video.

Apple is adding support for the WebM audio codec for Safari on iOS 15

How to use the Smart Search bar in Safari on iPhone and iPad

What you need to know

  • Apple will support the WebM audio codec with Safari in iOS 15.
  • macOS added support for the codec in Safari already.

Safari in iOS 15 is playing some catchup with macOS.

As spotted by 9to5Mac , the latest beta of iOS 15 has added support for the WebM audio codec in the Safari app. The codec, which has already been supported in Safari on macOS Big Sur , has been missing support for Safari on the iPhone. iOS 15 appears to be the time to line up that experience.

According to the report, Apple had hesitated to adopt WebM codes in the past but has recently brought them to macOS with both the audio and video codecs.

The WebM audio codec is part of the open media file format created by Google in 2010, which also includes the WebM video codec and WebP image extension. Apple has never been interested in adopting the WebP and WebM formats in the past, as Steve Jobs once said that Google's codecs were "a mess."The company has finally added support for WebP images to Safari with iOS 14 and macOS Big Sur. Another update to Safari 14 on macOS also added support for the WebM video codec, but this was never added to the iOS version of Safari. Now, with the WebM audio codec available in iOS, it's probably only a matter of time before Apple adds WebM video support to its mobile operating system.

Apple is expected to launch iOS 15 alongside the iPhone 13 this fall. Safari in iOS 15 has been completely redesigned with a floating and interactive search bar towards the bottom of the screen.

The new design has been met with some skepticism, leading Apple to make small changes to the user experience over the course of the iOS 15 beta releases.

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

WebM support

I have Big Sur 11.4.

I know that according to Apple Insider as of February 2021 they mentioned WebM is coming to Macs finally 11 years after it's launch... I was happy to hear that...

and even https://webm.html5.org ... tells me today with 11.4 my browser supports WebM...

OK... Macs are supposed to support WebM format now... but..

I have many WebM files on my computer and they only open in Chrome, Firefox or Opera.

I cannot open them with Safari. It's greyed out and dragging and dropping into a browser window shows a video file marked off and won't play.

Also WebP files don't work well in Safari. They play very poorly.

So... What is actually going on?

I have a website with WebM and WebP files and i'd like to host only one version of a file for everyone but due to the codec wars I host 3 different versions of each video for:

New Macs, 4k HEVC

Old Macs, 1080 HEVC

And PC or Non-Safari Computers. 4k VP9 (They don't support HEVC)

My 2015 Mac still won't play a 4k video even in Big Sur 11.4. But an iPhone 8 will... iOS 13 or so.

So a simple solution would have been everybody just use VP9 and WebM but... it seems that didn't happen... or if it did... I dunno why I can't.

So I just wanna know if Mac is really supporting WebM or not.

If I open https://www.webmproject.org/detect/ in Safari on Big Sur 11.5.1, despite stating otherwise, the embedded WebM video does in fact play. I cannot drag a WebM video into a Safari window, just as you stated.

  • detecting and converting incompatible media files I've read everything I can find on which video files will become incompatible after Mojave, including the forums, the internet and Apples support site. It's still unclear to me which video files will no longer be viewable with QuickTime X (or other macOS apps). My questions are as follow: If a file opens with QuickTime X without converting, is that a good sign that it will still play after Mojave? The Apple support mentions MPEG-4 remaining compatible, but what about files with .mpg extensions? What about MPEG-1 files? Is there any easy way to tell if a video file is 32-bit versus 64-bit? Does its icon showing its thumbnail (versus as a generic icon) in icon view in finder help determine which files need converting and which ones will continue to play in QuickTime after Mojave? I would certainly appreciate any advice from the experts on this forum who are definitely more knowledgable about this type of thing than I am! 426 2

Your link there says you would need an extension to view in Safari. But, I have no idea what WebM is or what use I would have for it, so I don’t have any ability to test the extension.

Video with transparency in Chrome, Edge, Firefox, Safari, iOS and Android, circa 2022

This post on using video with a trans­par­ent back­ground will prob­a­bly not age well. At least I  hope that is the case! Ide­al­ly, in the future, you can use a sin­gle .webm video file and it will work every­where. 

But, as I write this post in Jan­u­ary 2022 , after a full day of research and try­ing dif­fer­ent approach­es, I’ve got a <video> tag that will play a video with a trans­par­ent back­ground across a wide vari­ety of browsers.

  • Safari on Desk­top
  • Safari on iPhone

I assume that the oth­er browsers based on Chromi­um will also work, although I’ve not test­ed them when I write this. 

If you’re try­ing to get a video with trans­paren­cy work­ing, let me show you what I’ve done. I hope this saves you some time.

Source mate­r­i­al #

I’m lucky in that I’m start­ing with a nice short piece of pro­fes­­sion­al­­ly-pro­­duced video with an alpha chan­nel. If you don’t have an alpha chan­nel in your source video, you need to solve that prob­lem first.

The source video I had was very big. I used Adobe After Effects to trim and resize it to meet my needs. I want­ed no audio chan­nel on the video which allows me to auto­play the video using Javascript. I also resized the video dimen­sions. Pro tip : web video does not have to be the tra­di­tion­al video aspect ratio.

I export­ed that video using the Apple ProRes 4444 XQ . This will result in a file that is still not usable on the web, but it will be ready for the next step in the process.

After Effect Output Module Settings

My hard­ware #

Before going fur­ther, you should know I am using an Apple Sil­i­con Mac, a Mac­Book Pro. If you’re on any oth­er plat­form, your result may vary since I use the hard­ware accel­er­a­tion option in one of the video con­ver­sions we’ll dis­cuss below. This doesn’t mean you need a Mac, but I don’t have the hard­ware to test on oth­er plat­forms.

Shut­ter Encoder #

After many tests, I’ve cho­sen Shut­ter Encoder as the best encoder for this process. I tried FFm­peg, Hand­brake, Adobe Media Encoder, and sev­er­al oth­er online video encod­ing ser­vices. None of them worked as well as Shut­ter Encoder, which is free. If you find the app use­ful, you should sup­port the author. I did because I like the soft­ware I use to stick around.

Update, 10 MAY 2022 : When I wrote this post orig­i­nal­ly, I used Shut­tle Encoder ver­sion 15 . 7 dur­ing the encod­ing process. I worked on encod­ing anoth­er video, as described here, using Shut­tle Encoder ver­sion 15 . 9 , which failed. Based on what I’ve read, there is some issue with FFM­PEG in ver­sions after 15 . 7 . Rein­stalling ver­sion 15 . 7 allowed me to con­tin­ue to con­vert videos suc­cess­ful­ly. I hope the bug is fixed in future ver­sions of the soft­ware.

Update, 25 MAY 2023 : I recent­ly went through the process of cre­at­ing a video with an alpha chan­nel, as described in this post. I’m hap­py to report that using Shut­ter Encoder ver­sion 17 . 1 , the cur­rent ver­sion as of May 2023 , suc­cess­ful­ly encodes the alpha chan­nel. Based on the changel­og , it looks like this was fixed in Shut­ter Encoder ver­sion 16 . 8 .

Cre­at­ing a webm ver­sion of the video #

I’ve made two ver­sions of the video. The first is a .webm ver­sion. Shut­ter Encoder will allow you to pre­serve the alpha chan­nel when you’re cre­at­ing your webm. Let’s review the options I used.

Shutter Encoder settings for creating .webm with alpha channel

Add your source video in the Choose files area then select VP 9 as your func­tion. Under the Advanced fea­tures area, choose Enable alpha chan­nel .

Now click the Start func­tion but­ton and gen­er­ate your .webm video.

Cre­at­ing an H. 265 ver­sion of the video, and not an H. 264 video #

Now that Safari added sup­port for .webm , you might be won­der­ing why we’re mak­ing anoth­er ver­sion of the video at all. In my tests, Safari’s sup­port of .webm video doesn’t include sup­port for the alpha chan­nel. A black back­ground is shown where you’d expect the trans­paren­cy to be used. 

Why not use an .mp4 with an alpha chan­nel? That’s what we’re going to do, but it’s not the tra­di­tion­al H. 264 video you may be famil­iar with. 

After a lit­tle online research, you may incor­rect­ly dis­cov­er the .mp4 video file does not sup­port an alpha chan­nel. This was my assump­tion, too, but I was con­flat­ing an mp 4 file and an H. 264 video file as the same thing. There is a dif­fer­ence though. H. 264 is the codec, the piece of soft­ware, that con­verts the uncom­pressed video into a stream of com­pressed bits. The file­type, .mp4 (or .webm , or .avi , etc.) con­tains the stream of video and/​or audio. 

In oth­er words, the .mp4 file can use the H. 264 codec. The H. 264 cod­ed doesn’t sup­port hav­ing an alpha chan­nel. But there is a new­er codec called H. 265 . Spoil­er alert: it sup­ports the alpha chan­nel.

Using Shut­tle Encoder again, make the H. 265 ver­sion of the video. Let’s review the options I used.

Shutter Encoder settings for creating .mp4 with alpha channel

There are three options in the screen­shot above. 

After you’ve added your source video, select H. 265 as your func­tion. Under the Advanced fea­tures area, the Enable alpha chan­nel option should be checked auto­mat­i­cal­ly. Also, turn on the Hard­ware accel­er­a­tion option. In my tests, the hard­ware accel­er­a­tion was the only way to get Shut­tle Encoder to cre­ate the alpha chan­nel suc­cess­ful­ly. Depend­ing on your com­put­er, you may achieve dif­fer­ent results when using hard­ware accel­er­a­tion. 

Now click the Start func­tion but­ton and gen­er­ate your .mp4 video.

The video tag for your HTML #

Let’s look at <video> tag I’m using.

This video tag is for a small ani­ma­tion that plays inline and it has no audio. You can see those para­me­ters at the begin­ning of the video tag. I also have an id of ambientVideo which I use to trig­ger the ani­ma­tion with an Inter­sec­tion Observ­er that I’ll describe at the end of this post. (Read more about the options for the video tag in the MDN Web Docs .)

The two most impor­tant things are the order of the source tags and the type of each source.

The .mp4 source tag is the first tag. Browsers will see this as the first source, and if they can play it, that’s the one they’ll choose to use. In my tests, Safari on desk­top and on mobile will use this. Be sure you’ve got the type set to include the codecs por­tion. With­out that, you’ll find browsers that think they know how to play a .mp4 try­ing to play that video unsuc­cess­ful­ly because they are not aware of the hvc 1  codec. 

Next, include the link to the .webm source. This is what most browsers will end up dis­play­ing.

In case you’re won­der­ing, the ~@/assets path is how I refer to the root of my pub­lic fold­er. You need to use the path to the video that makes sense to your envi­ron­ment.

Bonus: Play video when it appears on the screen #

In my video tag, I’ve got an ID of ambientVideo .

I’ve post­ed the Javascript file I’m using in this gist: ambient-video-play-on-enter.js

Since you are here already, I’ll share it in this post too. 

In the first line, I look for my video tag with the id of ambientVideo . Next, I cre­ate a new Inter­sec­tionOb­serv­er. Yes, this code could be made to be more reusable, but it works for this pur­pose. 

What does this code do? #

Basi­cal­ly, when the video ele­ment comes into frame, we tell it to play. When it leaves the frame, it gets paused. 

If you want to cus­tomize when the Inter­sec­tion Observ­er trig­gers, check out the Inter­sec­tion observ­er options . As an exam­ple, my thresh­old set­ting of 0 . 5 means I want to detect the vis­i­bil­i­ty of my video when 50 % of it is vis­i­ble. You may need dif­fer­ent set­tings.

To make it work, I have the Inter­sec­tion Observ­er that I cre­ate start observ­ing, look­ing for the ambientVideo video ele­ment.

There's Never Been a Better Time for Used PC Hardware

8 tricks i use to keep my macbook clean (without damaging it), google gemini is going conversational on your phone, key takeaways.

  • The iCloud Passwords extension for Chrome is a game-changer for Mac users who rely on Safari and iCloud passwords integration.
  • Even if you primarily use Safari, having the iCloud Passwords extension on Chrome can ensure your passwords stay synced and accessible.
  • The extension is available for both Mac and Windows users, making it a convenient tool for keeping passwords easily accessible across devices.

Despite often flirting with various Chrome-based browsers on my Mac, I always fell back to Safari because of its integration with iCloud passwords. However, that largely changed when the iCloud Passwords extension from Chrome became available for Mac users. It's a must-have, even for people who still primarily use Safari.

How to Use iCloud Passwords on Chrome (or Arc)

I now use Arc as my everyday web browser because it has some killer features . Besides the way Arc handles bookmarks and favorites, I have very little to complain about. And since the Chromium-based browser can use Chrome extensions, it can also input my iCloud Passwords with Apple's own first-party extension. I needed to keep using Apple's iCloud Passwords too, because I still use Safari exclusively on my iPhone. This utility allows my phone and desktop passwords to stay synced and up-to-date.

The iCloud Passwords extension is freely available in the Chrome web store. If you search for it, instead of clicking the link, just make sure you find the one that’s published by Apple Inc.

Although my computer preference is a Mac, the iCloud Password extension for Chrome is available for Windows users too. It actually debuted for Windows and then became available on Mac afterward.

Requirements and Extension Considerations

To use the iCloud Passwords extension on a Mac you’ll need to be running macOS 14 Sonoma or later. That's the latest operating system that was released in 2023. (To use it on a Windows computer, the iCloud for Windows app in the Microsoft Store just needs to be compatible.)

After downloading and enabling the Chrome extension for Mac, you’ll need to verify your account by entering a six-digit code sent to one of your Apple devices. One of the biggest complaints about the extension, from its user reviews, is that it constantly needs to be authenticated and will frequently ask for this code.

In my use of it, that annoyance has been curtailed over time and various updates to the extension have lessened that criticism. Your mileage may vary, but my experience with it has largely been positive—even improving over time.

To be clear, iCloud Passwords are still managed by macOS and can still be accessed within the system settings in Sonoma. Your passwords are not stored in Chrome. The extension merely provides a bridge to access them in a browser besides Safari. If your Mac computer (or keyboard) has a Touch ID sensor that’s supported by the extension as well, so you can authorize passwords with a finger. The same way you would with Apple’s own browser.

An Extension to Install, Just as a Backup

I started trying to use the Arc browser on my Mac regularly before the macOS 14 Sonoma was out and before the iCloud Passwords extension was supported. In that time, I found a few passwords slipped through the crack and did not get added to my vault because I created them while using a browser other than Safari.

So even if you don’t plan on using alternative browsers often, it may be worth adding the iCloud Passwords extension to Chrome, Arc, or any other supported browser you have installed, just so your iCloud Passwords are available if you need them. I know I’ve seen occasions when certain websites worked better in Chrome. This is a great, free, extension available just in case you ever need it. Or, for iPhone owners eager to switch Mac browsers, this might be how you can finally do it.

How this browser extension is friendlier on my budget and the environment

  • Beni is a free browser extension for Chrome & Safari making sustainable clothing shopping easier.
  • It matches current items with secondhand options from over 40 online stores for budget-friendly prices.
  • Beni works by adding the extension, then selecting items to find exact or similar thrifted options.

While I'm not writing about the newest, most fashionable earbuds and headphones , I spend a lot of time shopping for clothes online. Admittedly, I'm one of those people who claim I have nothing to wear whilst staring at a closet full of clothes.

Finding the Beni extension was the perfect compromise that made shopping sustainably for my favorite items even easier while performing some much-needed online resale therapy.

As a dedicated clothing shopper, however, I've never been one to discriminate against a good brand or good deal, even if the item was pre-owned. In fact, I do a lot of my shopping via online or physical thrift stores in an attempt to do some good for the environment, combating the fast-fashion industry, and protecting my wallet.

So, finding the Beni extension was the perfect compromise that made shopping sustainably for my favorite items even easier while performing some much-needed online retail therapy -- or rather, resale therapy.

Bose's new Ultra Open earbuds are the fashion and function success I can't stop wearing

What is the beni shopping extension, free browser extension for chrome and safari.

Beni, is a free shopping extension available on your desktop for Chrome and Safari that works alongside your current shopping page to look for either exact or similar clothing items at over 40 second-hand online stores, including ThreadUp, The RealReal, Poshmark, Rent the Runway, and eBay for a more budget-friendly price.

Essentially, Beni streamlines second-hand shopping by matching the current desired (full priced) item with either the exact item or one similar via quality, second-hand thrifting apps.

Fairphone's new wireless earbuds take sustainability to the next level

How beni works when shopping online: streamlining secondhand.

Upon adding to your browser, you'll see a Beni browser extension icon - which is a green circle with orange sunglasses - in the bottom left corner of your webpage. That icon is your key to unlocking the best thrifting deals. Here's when to click on it.

  • Start shopping online as you normally would. Open your window to your usual favorite online outlet .
  • Select an item you like , whether you're tempted to add it to your cart or if you know it's an absolute must-have.
  • Click the green Beni icon in the bottom right corner, and you'll see up to 20 options for either the exact item, or similar items automatically displayed on the right side of your screen from third-party, second-hand outlets.
  • You can also like certain options to save them for later.

When you first download Beni, you'll be invited to fill out your typical sizes for your favorite brands to ensure that the browswer is pulling custom options.

How to download Beni on your desktop

Currently, Beni is only available on Chrome and Safari.

  • Enter 'Beni' in your search browser, and select 'Beni | Find it Secondand'
  • From the website, you'll be invited to add Beni to Chrome. Select the orange 'Add to Chrome' button on Beni's website.
  • A link will lead you to the Chrome store. Select the blue 'Add to Chrome' button.
  • Beni will invite you to input your typical sizes to curate more personalized search results.

How to download Beni on your iPhone

Currently, Beni is only available to download via the app or on the iPhone's Safari browser. According to the website, its working on bringing the extension to Android handsets soon.

Best sustainable smartphones: Expert tested and reviewed

Here's how to download the browser to safari on iphone..

  • You'll see a popup, then tap Beni and select 'always allow.'
