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 download on your phone ends in .avif, and the trouble starts the moment it leaves the browser. The viewer on your computer will not open it, 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 that not every program outside a browser opens.
Sites serve AVIF to cut bytes: the Alliance for Open Media, which maintains the format, puts it at over 50% smaller than JPEG, without describing the test. Browsers display it from Chrome 85, Firefox 93, Edge 121 and Safari 16 on (caniuse, September 2026). That built-in decoder is what this page uses. The browser reads the AVIF, draws it on a canvas and writes a standard JPEG for the programs and upload forms that ask for one.
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: that is the compression advantage AVIF gives up in exchange for a file that opens where you need it.
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, a starting point 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. If the size on the card reads higher than the original, that is normal in this direction.
What opens a .avif today, and what still refuses it
Support is decided program by program, which is why the same file displays fine on a web page and fails in the program you actually need. What is documented:
| Where it goes | Opens .avif? | According to |
|---|---|---|
| Chrome, Edge, Firefox, Opera | Chrome 85+, Edge 121+, Firefox 93+, Opera 71+ | caniuse, September 2026 |
| Safari | 16.0+ on iPhone and iPad; 16.1+ on Mac with macOS 13 Ventura | caniuse, September 2026 |
| WordPress media library | Since 6.5, if the server's image library supports AVIF | WordPress developer note, February 2024 |
| Email in Outlook for Windows 2007–2019 | No | caniemail tests, 2023 |
| Email in Gmail | Still images are converted to JPG | caniemail tests, 2023 |
| Desktop viewers, editors, upload forms | Depends on the program and version | Its own documentation |
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 a browser older than the versions in the table above — update it, or open this page in one that qualifies. On a phone, Safari on iOS 16 qualifies. Reading AVIF is all this page does with the format: LivreImage does not write AVIF today.
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: AVIF stores the picture in fewer bytes than JPEG can, and the difference comes back on the way out. The card prints both sizes. Quality 100 only bloats the file.
- 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 on the page you saved it from.
- 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
The platform picks the format, whatever name the file was uploaded under. In September 2026, Shopify's help center says it detects which formats the visitor's browser supports and delivers WebP or AVIF when it can; Wix's says uploaded images are converted to AVIF on the live site. So photo.jpg on a store can land in Downloads as photo.avif. WebP and AVIF for websites covers how sites serve the formats.
For a single picture, if your browser's right-click menu offers Copy image, copy instead of saving and press Ctrl+V on this page. For files already downloaded, converting is the fix; renaming the extension to .jpg is not, because it changes the name and leaves the content AVIF.
Frequently asked questions
How do I convert AVIF to JPG on Windows 11 without installing anything?
Open this page in a browser that displays AVIF (per caniuse in September 2026, Chrome 85 or Edge 121 and newer), drop the .avif in, press Generate images and download the .jpg. Nothing is installed; the browser you already have does the decoding.
Will the JPG open in older software?
The output is a JPEG written by your browser's encoder, with nothing of the AVIF left inside. If a program lists JPG or JPEG among the formats it opens, this file qualifies; no plug-in or codec for AVIF is involved.
Why is the JPG bigger than the AVIF?
AVIF is built on the AV1 video codec, and the Alliance for Open Media puts it at over 50% smaller than JPEG, without describing the test. 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?
Not necessarily. Drag it onto a blank tab: if it does not display there, this browser cannot decode AVIF and the page cannot either. Per caniuse, Edge before 121 and Safari before 16.1 on a Mac (16.0 on iPhone) are in that group; update, or use a browser that qualifies.
Can I convert AVIF to JPG on an iPhone or an Android phone?
Yes, in a phone browser that displays AVIF; per caniuse, Safari on iOS 16 or later does. Pick the file, generate, and download the .jpg. If no thumbnail appears in the queue, that browser cannot decode the format.
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, so some information is lost; whether it shows is what Compare is for. 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.
