Convert AVIF to JPG
Saved a picture and got a .avif nothing on your computer will open? Your browser decodes it and writes a plain .jpg here — one file or a folder, no upload.

The picture you saved from a news site, a stock-photo library or a Chrome download on your Android phone ends in .avif, and the trouble starts the moment it leaves the browser. Windows Photos asks you to install a codec, Photoshop 2024 stops at "Could not complete your request", and the job application or listing form you were filling out lists .jpg, .jpeg and .png and nothing else. The image is fine. It is stored in a format most desktop software learned only recently, if at all.
Sites serve AVIF because it packs a photo into roughly half the bytes of a JPEG at the same look, and every current browser can show it: Chrome since version 85, Firefox since 93, Safari since 16, Edge since 121. That built-in decoder is what this page uses. The browser reads the AVIF, draws it on a canvas and writes a standard JPEG that Paint, Word, a ten-year-old Photoshop and any upload validator accept.
Nothing is sent anywhere in the process. Decoding and encoding both happen on your own device, so the file never leaves it, and a whole folder can go through at once with the results bundled into one .zip. Expect the JPG to be larger than the AVIF, often two to three times — that is the compression advantage AVIF gives up in exchange for a file that opens everywhere.
How it works
JPG is already selected on the format bar, so the whole job is three clicks and one decision about quality.
Add the .avif files
Drag them out of Downloads or the folder your phone synced to, use the file picker, or paste with Ctrl+V. The browser decodes each file as it lands: a thumbnail in the queue means it was read and will convert. A file that never gets a thumbnail is one this browser cannot decode — see the browser section below.
Check the quality slider
JPG is highlighted and the slider sits at 82, which is right for photos. Push it to 90–95 for a screenshot, a chart or anything with small text. If the AVIF has a transparent background, this is the step where it gets filled with white; switch the format to PNG to keep it clear.
Generate and download
Press Generate images, open Compare on a card and drag the handle to check the result against the source, and download files one at a time or the whole batch as a .zip. The size on the card reads higher than the original — normal in this direction.
What opens a .avif today, and what still refuses it
Support arrived in browsers first and everywhere else years later, which is why the same file displays fine on a web page and fails in the program you actually need.
| Where you open it | Opens .avif? | Notes |
|---|---|---|
| Chrome 85+, Firefox 93+, Safari 16+, Edge 121+ | Yes | Drag the file onto a blank tab and it displays |
| Android 12 and later (Gallery, Google Photos) | Yes | Older Android: blank or broken thumbnail |
| macOS Preview and Finder | Ventura (13) and newer | Preview can also export a JPEG, one file at a time |
| Windows 10/11 Photos, Explorer thumbnails, Paint | Only with the AV1 Video Extension | Free in the Microsoft Store; some 10-bit files still fail |
| Photoshop | 26.8 (June 2025) and newer | Older versions: "Could not complete your request" |
| GIMP | 2.10.22 and newer | Built in, no plug-in |
| Classic Windows Photo Viewer, pre-2021 viewers | No | Nothing to install; convert instead |
| Upload forms with an extension list | Rarely | .jpg, .jpeg, .png is the usual list |
The AVIF decoder is the browser you are reading this in
No server and no bundled decoder are involved: the page hands each file to the same code your browser uses to display AVIF on web pages, takes the pixels back through a canvas and writes the JPEG right there. The one condition follows from that: a browser that cannot display AVIF cannot convert it here either.
The five-second check: drag the .avif onto an empty tab. If it displays, this page will convert it. A broken-image icon means Safari before 16, Edge before 121, or a browser years out of date — update, or open this page in a current Chrome or Firefox. On a phone, Safari on iOS 16 and any recent Chrome on Android qualify. The Store's AV1 Video Extension changes nothing for the browser; it exists for Photos and Explorer.
What the JPG keeps, and what it gives up
The conversion is a full decode and re-encode, so a few properties change on the way:
- Size goes up. A 120 KB AVIF typically comes back as a 250–400 KB JPG at quality 82, since AVIF compresses about twice as efficiently. Quality 100 only bloats the file; the re-encode is invisible from 85 up.
- Transparency goes. JPEG has no alpha channel, so every transparent pixel is painted white. For a logo or a cutout, select PNG on the format bar before generating.
- Depth and HDR flatten. A 10-bit or HDR AVIF is drawn at 8 bits per channel in standard dynamic range, so highlights can look a little dimmer than they did in Chrome.
- Animation stops at frame one. An animated AVIF contributes only its first frame; JPEG cannot hold a sequence.
- Dimensions stay the same up to 10,000 px on the longer side; anything bigger is scaled down to that edge. EXIF is stripped from every output.
Why the download was .avif when the page showed a .jpg
Image CDNs read the Accept header your browser sends and serve the lightest format it can display, whatever name the page's HTML shows. Chrome asks for AVIF, so Save image as writes the AVIF bytes it received, and photo.jpg on a stock-photo site, a store or a newspaper lands in Downloads as photo.avif.
For a single picture, Copy image instead of Save image as puts decoded pixels on the clipboard, and Ctrl+V drops them straight into this page. For files already downloaded, converting is the fix; renaming the extension to .jpg is not, because Photos, Photoshop and strict upload checks identify the file by its header, which still says AVIF.
Frequently asked questions
How do I convert AVIF to JPG on Windows 11 without installing anything?
Open this page in Edge or Chrome, drop the .avif in, press Generate images and download the .jpg. Nothing is installed; the browser you already have does the decoding. The AV1 Video Extension is only needed if you also want Photos and Explorer to show .avif files.
Will the JPG open in Photoshop 2023 or Word?
Yes. The output is a standard baseline JPEG, the same structure a camera writes, so any version of Photoshop, Word, Paint or the classic Windows Photo Viewer opens it with no plug-in or codec.
Why is the JPG two to three times bigger than the AVIF?
AVIF is built on the AV1 video codec and stores the same picture in far fewer bytes than JPEG can. The growth is the price of compatibility. If a form caps the size in KB, lower the quality slider here or send the JPG through Compress image.
The card shows an error after Generate. Is the AVIF corrupt?
Usually not. Drag it onto a blank tab: if it does not display there, this browser cannot decode AVIF and the page cannot either. Safari before 16 and Edge before 121 are the common cases; a current Chrome or Firefox will read it.
Can I convert AVIF to JPG on an iPhone or an Android phone?
Yes, in the phone's browser: Safari on iOS 16 or later and any current Chrome on Android decode AVIF. Pick the file from Files or Downloads, generate, and the .jpg saves to the same place.
The AVIF had a transparent background. What will the JPG look like?
The transparent area becomes solid white, because JPEG has no alpha channel. To keep the cutout, change the format from JPG to PNG before pressing Generate.
Does converting AVIF to JPG lose quality?
There is a lossy re-encode, but at the default of 82 it is not visible on a photo and at 85 or above it is invisible. What you cannot get back is detail the AVIF already discarded; a higher number only makes the file bigger.
These are photos from a client's private gallery. Are they uploaded to convert them?
No. The AVIF is decoded and the JPG encoded by your browser on your device; the image is never sent to a server, and closing the tab leaves nothing behind. Every output also has its EXIF removed.
