How to Open One or Convert to JPG"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">You right-clicked a photo on a news site, chose <em>Save image as\u2026<\/em>, and got <code>photo.avif<\/code> \u2014 a file the Windows Photos app shrugs at, your photo editor won\u2019t import, and the next upload form rejects. Nothing is corrupt. AVIF is a real (and genuinely excellent) image format; it\u2019s just newer than a lot of the software around it. This guide explains what an AVIF file actually is, why they\u2019re suddenly showing up in your Downloads folder, exactly what opens one natively \u2014 verified against caniuse, Apple\u2019s WebKit release notes, Microsoft\u2019s Store listings, and the AOMedia spec \u2014 and the 30-second escape hatch: converting it to a JPG that opens anywhere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Quick answer:<\/strong> An <code>.avif<\/code> file is an image in the <strong>AV1 Image File Format<\/strong> \u2014 an open, royalty-free format from the Alliance for Open Media that compresses much harder than JPEG (AOMedia cites <strong>over 50% file-size savings vs JPEG<\/strong>). Your file won\u2019t open because the app you\u2019re using has no AV1 decoder. Three fast fixes: <strong>drag it into any modern browser<\/strong> (Chrome, Firefox, Edge, and Safari all display AVIF), <strong>install Microsoft\u2019s free AV1 Video Extension<\/strong> on Windows, or <strong><a href=\"https:\/\/www.xconvert.com\/convert-avif-to-jpg\">convert it to JPG<\/a><\/strong> so it opens everywhere, forever.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Jump to a section<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"#what\">What an AVIF file actually is<\/a><\/li><li><a href=\"#why\">Why you suddenly have .avif files<\/a><\/li><li><a href=\"#support\">What opens AVIF natively (and what doesn\u2019t)<\/a><\/li><li><a href=\"#open\">Three ways to open it right now<\/a><\/li><li><a href=\"#tool\">Convert AVIF to JPG on xconvert<\/a><\/li><li><a href=\"#faq\">FAQ<\/a><\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what\">What an AVIF file actually is<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AVIF stands for AV1 Image File Format.<\/strong> Technically, it\u2019s a still image (or image sequence) encoded with the <strong>AV1 video codec<\/strong> and stored in a HEIF container \u2014 MDN describes it as \u201ca powerful, open source, royalty-free file format that encodes AV1 bitstreams in the High Efficiency Image File Format (HEIF) container.\u201d In plain terms: it borrows the compression smarts of a modern video codec and applies them to a single picture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The format is published by the <strong>Alliance for Open Media (AOMedia)<\/strong> \u2014 the industry consortium behind the AV1 codec, organized as a project of the Joint Development Foundation and backed by companies including Google, Apple, Microsoft, Amazon, Netflix, and Mozilla. The current specification is version 1.2.0. Two properties matter most:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>It\u2019s dramatically smaller.<\/strong> AOMedia\u2019s own figures: <strong>over 50% file-size savings compared to JPEG and over 30% compared to WebP<\/strong> at comparable quality. MDN reports the same ballpark (lossy AVIF around 50% smaller than JPEG; a median 50% vs WebP\u2019s 30% on the same test set). As always with compression, the exact saving is content-dependent \u2014 treat these as typical, not guaranteed.<\/li><li><strong>It\u2019s royalty-free and feature-rich.<\/strong> The spec supports lossy <em>and<\/em> lossless compression, transparency (alpha), animation, HDR, and wide color gamut \u2014 things JPEG structurally can\u2019t do.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">So AVIF isn\u2019t some proprietary oddity \u2014 it\u2019s the web\u2019s next-generation image workhorse. The catch is purely one of age: mainstream support only began with Chrome 85 in August 2020, and plenty of desktop software still hasn\u2019t caught up. (For how it stacks up against the other modern format, see <a href=\"https:\/\/www.xconvert.com\/blog\/avif-vs-webp-next-gen-image-formats\/\">AVIF vs WebP<\/a>.)<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why\">Why you suddenly have .avif files<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You almost certainly didn\u2019t choose AVIF \u2014 <strong>a website chose it for you.<\/strong> Because AVIF cuts image weight so much, news sites, e-commerce platforms, and image CDNs increasingly serve AVIF to any browser that advertises support for it (browsers announce <code>image\/avif<\/code> in the HTTP <code>Accept<\/code> header, and the server picks the best format it can send). The page even looks like it\u2019s showing you a JPEG \u2014 same picture, same layout.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The surprise comes at save time. <strong>Right-click \u2192 Save image as\u2026 saves the exact bytes the server sent<\/strong>, so what lands on disk is <code>image.avif<\/code>, not <code>image.jpg<\/code> \u2014 even if the URL said \u201cjpg\u201d somewhere. Chrome and Edge have no setting to change this (there\u2019s a long-standing open Chromium feature request asking for a \u201cdownload as JPG\/PNG\u201d option), so the AVIF files pile up in Downloads until you hit an app that can\u2019t read one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WebP owners of a few years ago will recognize this exact story \u2014 the same serve-modern-formats mechanism made <code>.webp<\/code> the mystery extension of 2020 (see <a href=\"https:\/\/www.xconvert.com\/blog\/convert-webp-to-png-or-jpg\/\">convert WebP to PNG or JPG<\/a>). AVIF is simply the next, more aggressive round.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"support\">What opens AVIF natively (and what doesn\u2019t)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Browser support is now excellent \u2014 <strong>about 93% of web users globally<\/strong> (caniuse, June 2026). Desktop apps and OS utilities are the weak spot. Verified state:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Where<\/th><th>Opens AVIF?<\/th><\/tr><\/thead><tbody><tr><td>Chrome<\/td><td>Yes \u2014 since Chrome 85 (Aug 2020)<\/td><\/tr><tr><td>Firefox<\/td><td>Yes \u2014 still images since 93 (Oct 2021); animated AVIF since 113<\/td><\/tr><tr><td>Edge<\/td><td>Yes \u2014 but only since Edge 121 (Jan 2024); older Edge fails<\/td><\/tr><tr><td>Safari<\/td><td>Yes \u2014 Safari 16 on iOS 16 \/ iPadOS 16 \/ macOS Ventura; Safari 16.4 (Mar 2023) extended it to macOS Big Sur and Monterey and added animated AVIF<\/td><\/tr><tr><td>macOS<\/td><td>Ventura (13) and later decode it system-wide \u2014 Preview and Quick Look open it like any JPEG; on Big Sur\/Monterey it\u2019s Safari-only<\/td><\/tr><tr><td>iPhone \/ iPad<\/td><td>iOS 16 and later ship an AVIF decoder (Safari, Files; individual apps vary)<\/td><\/tr><tr><td>Android<\/td><td>Android 12 and later \u2014 platform-level AVIF support per Google\u2019s Android 12 release notes<\/td><\/tr><tr><td>Windows 10 \/ 11 (Photos, File Explorer)<\/td><td><strong>Not reliably out of the box<\/strong> \u2014 Microsoft\u2019s fix is the free <strong>AV1 Video Extension<\/strong> (plus the HEIF Image Extension) from the Microsoft Store<\/td><\/tr><tr><td>Older software: Photoshop before 26.8, many upload forms, assorted editors and viewers<\/td><td>Generally no \u2014 this is where conversion earns its keep<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Two rows deserve expansion:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Windows.<\/strong> Microsoft\u2019s HEIF Image Extension listing states the AV1 Video Extension package must be installed to view images stored in HEIF files that use the <code>.avif<\/code> extension \u2014 i.e., stock Windows typically has no AVIF decoder until you add the free extensions. Even then, community reports on Microsoft\u2019s Q&amp;A forums describe some AVIF files still refusing to open in Photos, so the browser (or a converted JPG) remains the dependable path.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Creative apps.<\/strong> Adobe only added native open\/edit\/save for AVIF in <strong>Photoshop 26.8 (June 2025)<\/strong>. Anything older \u2014 and a long tail of other editors, printers\u2019 upload portals, CMS media libraries, and form uploaders \u2014 will bounce the file. That long tail is why \u201cjust convert it to JPG\u201d stays the pragmatic answer even in 2026.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"open\">Three ways to open it right now<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Drag it into a browser.<\/strong> Any current Chrome, Firefox, Edge, or Safari window will render the file instantly \u2014 this is the zero-install way to at least <em>see<\/em> the image. Viewing isn\u2019t editing or uploading, though.<\/li><li><strong>Add the decoder to your OS.<\/strong> Windows: install Microsoft\u2019s free <strong>AV1 Video Extension<\/strong> and <strong>HEIF Image Extension<\/strong> from the Microsoft Store. Mac: update to Ventura or later. This fixes double-click viewing on your machine \u2014 but not the file\u2019s compatibility with other people, older software, or upload forms.<\/li><li><strong>Convert it to JPG or PNG.<\/strong> The only fix that travels with the file. One important non-fix first: <strong>renaming <code>photo.avif<\/code> to <code>photo.jpg<\/code> does nothing<\/strong> \u2014 the extension changes but the bytes are still AV1, and apps decode the bytes. A real conversion re-encodes the image, which is what the step below does.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Pick JPG for photos you\u2019ll share, email, or upload; pick PNG if the image has transparency you need to keep (JPEG has no alpha channel).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tool\">Convert AVIF to JPG on xconvert<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.xconvert.com\/convert-avif-to-jpg\">xconvert AVIF to JPG converter<\/a> turns the file into a universally supported JPG in under a minute, no account needed:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>Open <a href=\"https:\/\/www.xconvert.com\/convert-avif-to-jpg\">xconvert.com\/convert-avif-to-jpg<\/a> and click <strong>Upload<\/strong> \u2014 add one or more <code>.avif<\/code> files <strong>From my Computer<\/strong>, <strong>From Google Drive<\/strong>, or <strong>From Dropbox<\/strong> (drag &amp; drop works too).<\/li><li>That\u2019s genuinely all that\u2019s required \u2014 the defaults are tuned for the best result, with the <strong>Quality Preset<\/strong> set to <strong>Very High (Recommended)<\/strong>.<\/li><li>Optionally, open <strong>Advanced Options<\/strong> (the gear) to take control: pick a different <strong>Quality Preset<\/strong>, set a <strong>Specific file size<\/strong> if the JPG must fit under an upload cap, or shrink dimensions under <strong>Image resolution<\/strong>.<\/li><li>The <strong>File extension<\/strong> dropdown lets you choose <strong>JPEG<\/strong> or <strong>JPG<\/strong> \u2014 same format, just whichever extension your workflow expects.<\/li><li>Click <strong>Convert<\/strong>, then download your files \u2014 individually or as a ZIP, with no watermark.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Your image is processed on our servers and deleted automatically a few hours later \u2014 nothing stays around.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faq\">FAQ<\/h2>\n\n\n\n<h5 class=\"wp-block-heading\">Why can\u2019t I open an AVIF file?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Because the app you\u2019re opening it with has <strong>no AV1 decoder<\/strong>. AVIF is young \u2014 browser support only started in 2020 (Chrome 85), Windows needs Microsoft\u2019s free extension, and Photoshop couldn\u2019t open one natively until version 26.8 in mid-2025. The image itself is fine. View it in any modern browser, or <a href=\"https:\/\/www.xconvert.com\/convert-avif-to-jpg\">convert it to JPG<\/a> for software that will never learn AVIF.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">How do I open an AVIF file on Windows 10 or 11?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Install Microsoft\u2019s free <strong>AV1 Video Extension<\/strong> (and the HEIF Image Extension) from the Microsoft Store \u2014 Microsoft\u2019s own listing notes the AV1 extension is required to view <code>.avif<\/code> images. If Photos still balks (a known, community-reported issue with some AVIF files), drag the file into Edge or Chrome to view it, or convert it to JPG so it opens in everything.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Why are images suddenly saving as AVIF instead of JPG?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Websites and CDNs now <strong>serve AVIF to browsers that support it<\/strong> because it\u2019s dramatically lighter than JPEG \u2014 and \u201cSave image as\u2026\u201d writes exactly what the server sent. You never picked AVIF; the site did. The same thing happened with WebP a few years earlier.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Can I make Chrome save JPG instead of AVIF?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No \u2014 there\u2019s no built-in setting.<\/strong> The format is the website\u2019s choice, and Chromium\u2019s issue tracker has an open feature request for a save-as-JPG\/PNG option, but it hasn\u2019t shipped. Practical options: take the converted route after download, or on some sites, find a direct link to the original file. Renaming the extension does <strong>not<\/strong> convert it.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Is AVIF better than WebP or JPEG?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">For compression, <strong>yes<\/strong>: AOMedia cites over 50% savings vs JPEG and over 30% vs WebP at comparable quality, and AVIF adds HDR, wide gamut, transparency, and animation. Its weaknesses are ecosystem age (Edge only added it in 2024) and no progressive rendering. Full comparison: <a href=\"https:\/\/www.xconvert.com\/blog\/avif-vs-webp-next-gen-image-formats\/\">AVIF vs WebP<\/a>.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Does converting AVIF to JPG lose quality?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Marginally \u2014 JPEG is a lossy format, so re-encoding always costs a little, and JPEG can\u2019t keep AVIF-only features (transparency gets flattened; HDR is tone-mapped down to standard range). At a high quality setting like the converter\u2019s <strong>Very High (Recommended)<\/strong> preset the difference is rarely visible for everyday photos. Keep the original <code>.avif<\/code> if you may need those extras later; convert a copy for compatibility.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sources<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Last verified 2026-07-15.<\/em><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/aomedia.org\/specifications\/avif\/\">AOMedia \u2014 AVIF specification<\/a> \u2014 publisher of the format; spec v1.2.0; \u201cover 50%\u201d savings vs JPEG and \u201cover 30%\u201d vs WebP; lossy\/lossless, HDR, WCG, transparency, animation.
