AVIF is a modern image format designed to reduce file sizes while preserving strong image quality. It can store photographic images, transparency, animation, high dynamic range content and other features that are useful on the web. However, file size is only part of the decision. An AVIF image also needs to work in the browser, device, application or publishing platform where people will use it.
AVIF compatibility has improved considerably, but it is not identical everywhere. A recent web browser may display AVIF without difficulty, while an older browser, image editor, content management system or social media service may not recognize the file. This guide explains the current compatibility picture and shows how to use AVIF without creating avoidable problems for visitors or team members.
What AVIF compatibility actually means
When people ask whether AVIF is supported, they may be asking about several different things. A platform can support one part of the format but not another.
- Decoding means opening or displaying an AVIF file.
- Encoding means creating or exporting an AVIF file.
- Uploading means accepting AVIF through a website, app or content management system.
- Editing means changing the image and saving it again.
- Processing includes generating thumbnails, previews, metadata and optimized versions.
For example, a browser may decode AVIF correctly, but a website’s upload form may reject the file. An operating system may show an AVIF thumbnail, while an older image editor cannot open it. Compatibility therefore depends on both the software version and the task you want to perform.
AVIF support in major web browsers
Current versions of the main desktop and mobile browsers generally support still AVIF images. This includes Chromium-based browsers such as Google Chrome, Microsoft Edge, Brave and Opera, along with Firefox and Safari on modern Apple devices and computers.
Support was added at different times. Chrome and Chromium-based browsers adopted AVIF earlier than some other browsers. Firefox support became available in modern releases, and Safari support arrived with Safari 16 on supported Apple operating systems. Older browser versions may not display the format even when the device itself is relatively recent.
Browser support also depends on the operating system. A browser may use the operating system’s image libraries or its own decoding code. In practice, this means that testing only one version of Chrome or Safari does not prove that every visitor will have the same result.
| Browser or browser family | Modern AVIF support | Main compatibility consideration |
|---|---|---|
| Google Chrome and Chromium browsers | Yes in current versions | Older versions and embedded browser components may differ |
| Mozilla Firefox | Yes in current versions | Very old releases may need a fallback |
| Apple Safari | Yes in current versions | Safari 16 or later is the important general baseline, with older Apple systems varying |
| Microsoft Edge | Yes in current Chromium-based versions | Legacy Edge and older Windows components are different |
| Internet Explorer | No native AVIF support | Use a fallback such as WebP or JPEG |
Browser support is usually sufficient for a new website that serves AVIF with a fallback. It is less safe to assume that every visitor can open an AVIF file directly from a download link, email attachment or older web application.
How websites provide a fallback
A fallback is an alternative image format served when the preferred format is not supported. Web developers commonly use the HTML picture element to offer AVIF first and WebP or JPEG afterward. The browser chooses the first format it can display.
For example, a website may provide AVIF for browsers that support it, WebP for browsers with older AVIF support, and JPEG as a broad compatibility option. The exact setup depends on the site’s image system, but the principle is simple: use AVIF as an option rather than making every visitor depend on it.
Content delivery networks and image optimization services can also select a format based on the request from the browser. This can simplify delivery, although the service still needs to be configured correctly and tested with real browser versions.
AVIF on phones and tablets
Modern Android phones and tablets usually handle AVIF well when the operating system and app are up to date. Chrome for Android and other current Chromium-based browsers generally display AVIF images. Android support can still vary across manufacturers, older operating system versions and built-in gallery applications.
On Apple devices, AVIF support is available in modern versions of iOS, iPadOS and macOS through Safari and other updated software. Devices that cannot update to a sufficiently recent operating system may have more limited support. A new browser app cannot always overcome limitations in the underlying system or an older application.
Mobile compatibility also involves more than viewing. A phone may display an AVIF from a website but fail to show a thumbnail in an older file manager. A messaging app may convert the image, reject it or send it as an unrecognized attachment. The result depends on the app’s own image pipeline.
If your audience uses a wide range of phones, serve AVIF on websites with a fallback. For files that people will download and share between devices, WebP, JPEG or PNG may be more convenient unless you know that all recipients use compatible software.
Desktop operating systems and file managers
Windows, macOS and Linux can all work with AVIF, but support is affected by the operating system version and installed components.
On Windows, current browsers can display AVIF even when the default file viewer or an older application cannot. Some Windows installations may need an appropriate image extension or a newer Photos app to open AVIF files outside the browser. Thumbnails and previews can also depend on optional codecs, file manager support and system updates.
Recent macOS versions and Apple applications have better AVIF support than older releases. Even so, compatibility is not automatically shared by every program installed on a Mac. A browser, Preview, Photos, design application and file upload tool may each use different image libraries.
Linux support varies by distribution, desktop environment and installed libraries. Current browsers usually provide a reliable way to view AVIF online, while image viewers, file managers and editing tools may need updated packages. If you are preparing files for a Linux-based workflow, test the exact application rather than relying only on the operating system name.
For routine personal use, opening an AVIF in a current browser is often the easiest option. For professional workflows, check whether the file needs to pass through several programs, because the least compatible program in that chain determines what you can do.
Image editors and graphics applications
AVIF support in image editors is improving, but it is less uniform than browser support. Some current editors can open and export AVIF directly. Others can open it only through a plugin, an updated image library or an operating system component. Some applications can read still AVIF but do not preserve animation, HDR information, transparency settings or metadata when exporting.
Professional applications may also treat AVIF as a delivery format rather than a working format. A photographer or designer may keep the original RAW, TIFF, PSD or PNG file for editing, then export AVIF for a website. This approach avoids losing important layers, color information or editability in the production file.
Before adopting AVIF in a shared workflow, test these tasks:
- Opening an AVIF from a local folder
- Viewing transparency and animation correctly
- Preserving color profiles and metadata when needed
- Editing and exporting the image again
- Generating thumbnails and previews
- Sending the file to the next application in the workflow
When an editor cannot open AVIF, converting it to PNG, JPEG or WebP may solve the immediate problem. If you need to make repeated changes, convert from the highest-quality original available instead of repeatedly converting an already compressed AVIF.
CMS, website builders and upload systems
A website can display AVIF correctly while its content management system does not accept AVIF uploads. Upload restrictions may be set by the platform, hosting provider, security configuration or media library. Some systems accept the file but fail to create thumbnails, read its dimensions or include it in image optimization features.
WordPress and other publishing systems can behave differently depending on the version, server configuration and installed plugins. A modern setup may support AVIF natively, while an older installation needs an image optimization plugin or server-side library. If an upload fails, the cause may be MIME type validation, missing server support or a thumbnail generator that does not understand AVIF.
Website builders and online stores often process uploaded images automatically. They may convert AVIF to another format, ignore the file, create a broken preview or remove metadata. Always check the published page, not just the upload confirmation.
If your platform does not accept AVIF, you can convert the image to WebP or another supported format before uploading. The TopWebP image conversion tool can help when you need a browser-based way to convert an image to WebP without installing desktop software. WebP is widely supported and is often a practical alternative for websites that are not ready for AVIF.
Social media, email and messaging apps
Social networks and messaging services often apply their own image rules. Even if a service allows AVIF uploads, it may convert the image during processing. Other services may reject AVIF, display only a generic file icon or show a preview that works on one device but not another.
Email is another area where caution helps. A recipient’s email app, webmail interface or security scanner may not display an AVIF attachment inline. A link to an AVIF on a modern website may work, but attaching AVIF directly is less predictable than using JPEG or PNG.
For public posts, newsletters and files shared with a broad audience, use the format recommended by the service. JPEG remains a dependable choice for photographs, while PNG is useful for many simple graphics and transparency needs. WebP may work in more modern services, but it is still wise to test the exact destination.
AVIF features that can affect compatibility
Not every AVIF file is equally simple. AVIF can include features that some software handles differently.
Transparency
AVIF can store an alpha channel, which is the extra image information used for transparent or partially transparent pixels. A compatible viewer should display the transparency, but an older application may show a solid background, discard the alpha channel or fail to open the file.
Animation
Animated AVIF is supported less consistently than a single still image. A browser may play an animated file while an image editor shows only the first frame. Some applications may treat it as a normal still image or reject it. If animation must work across many platforms, test the destination carefully and consider animated WebP or GIF where appropriate.
HDR and wide color
High dynamic range, or HDR, describes images with a wider brightness range than standard images. AVIF can be used for HDR and wide color content, but the result depends on the display, operating system, browser and application. A device without an HDR display may tone-map the image, which means it converts the appearance to fit its capabilities. Color can therefore look different even when the file opens successfully.
Metadata and color profiles
Metadata is information stored inside an image, such as camera details, orientation, location or copyright data. Image processors may remove some or all metadata when converting or optimizing an AVIF. If color accuracy, orientation or copyright information matters, inspect the result after processing rather than assuming it was preserved.
How to test AVIF before using it
A practical compatibility test should match the way people will use your images. Testing one local file in one current browser is not enough for an important website or business workflow.
- Test a photographic AVIF, a transparent graphic and, if relevant, an animated or HDR file.
- Open each file in the browsers used by your audience, including at least one older supported version if your analytics show it is still common.
- Check current Android and Apple devices, plus any older devices that receive meaningful traffic.
- Upload the files to your actual CMS, store, email system or social platform.
- Check thumbnails, downloads, image editing, caching and the final published page.
- Confirm that a WebP, JPEG or PNG fallback appears when AVIF is unavailable.
Also test a direct file URL, because a browser fallback on a web page does not change what happens when someone downloads or opens the AVIF file separately.
Choosing AVIF, WebP or another format
AVIF is a strong choice when you want efficient delivery and your website can provide fallbacks. It is particularly useful for photographic images, large image collections and pages where image transfer size affects loading time. It is not automatically the best working format for every application.
WebP is often easier to use across older tools and upload systems while still offering modern compression and transparency. JPEG remains broadly compatible for photographs without transparency. PNG is useful for lossless graphics, screenshots, text-heavy images and transparency, although it can produce larger files for photographs.
| Use case | Practical first choice | Why |
|---|---|---|
| Modern website with format detection | AVIF with WebP or JPEG fallback | Combines efficient delivery with broad access |
| Website with limited AVIF support | WebP or JPEG | Usually easier to upload and process |
| Photograph shared with unknown recipients | JPEG | Very broad application support |
| Transparent web graphic | AVIF, WebP or PNG | Choice depends on platform and editing needs |
| Source file for repeated editing | Original, TIFF, PSD or PNG as appropriate | Preserves workflow features better than a delivery format |
The best format depends on the complete path from creation to display. A smaller AVIF is not useful if your publishing system rejects it or your customers cannot open the downloaded file.
Practical ways to avoid compatibility problems
Keep an original version of important images and create AVIF derivatives for delivery. This gives you a reliable source if you need to edit, resize or convert the image later.
Use content negotiation or the HTML picture element for public websites. Do not replace every JPEG or PNG with an AVIF file unless you have verified the browser and application requirements of your audience.
Check the correct MIME type when serving files. AVIF images should be delivered as image/avif. An incorrect server configuration can make a supported browser treat the file as an unknown download.
Monitor broken images and upload errors after deployment. Compatibility can change when you update a CMS, replace an image processing library or change a CDN. A small test set run after major changes can catch problems early.
Frequently asked questions
Does Chrome support AVIF?
Yes. Current versions of Google Chrome and most Chromium-based browsers support still AVIF images. Very old browser versions, embedded browser components and outdated applications may not. A website should still provide a fallback when it needs to support older software.
Does Safari support AVIF?
Current Safari versions support AVIF on supported versions of macOS, iOS and iPadOS. Safari 16 is the commonly used general baseline for AVIF support, but older Apple devices may be unable to update to that version. Test the operating systems used by your audience.
Can all phones open AVIF files?
No. Modern Android and Apple devices generally handle AVIF through updated browsers, but older operating systems, gallery apps and file managers may not. A phone displaying AVIF on a website does not guarantee that every app on the phone can open an AVIF attachment.
Why can my browser display AVIF but my image editor cannot?
Browsers and image editors use different decoding libraries and support different features. The editor may be outdated, may require a plugin or may not support transparency, animation, HDR or metadata in the same way. Update the editor or convert the image to a format it handles reliably.
Is AVIF better than WebP?
Neither format is best for every situation. AVIF can provide excellent compression and supports advanced image features, while WebP is often easier to use across older applications and publishing systems. For websites, offering AVIF with WebP or JPEG fallback is usually more flexible than choosing only one format.
Can I upload AVIF to WordPress?
That depends on the WordPress version, server image libraries, hosting setup and installed plugins. Some current configurations accept and process AVIF, while others reject the upload or cannot create thumbnails. Test the complete media workflow, or convert the image to WebP before uploading if your setup does not support AVIF.
Will social media websites accept AVIF?
Support varies by service and can change over time. A platform may reject AVIF, accept it and convert it, or show it only in certain upload paths. For predictable results, use the formats recommended by the destination and check the final post or preview after uploading.
Does AVIF support transparency and animation?
AVIF can support both transparency and animation, but applications do not handle those features equally. A browser may display an animated AVIF while an editor shows only its first frame. Test the exact file type and destination, especially when transparency or animation is essential.
What should I do if someone cannot open my AVIF file?
Convert a copy to WebP, JPEG or PNG based on the image content and the recipient’s needs. Keep the original AVIF and source file if quality or editing information matters. For a website, configure a fallback instead of asking visitors to install special software.
