What is a AVIF file?
AVIF is the picture form of the AV1 video codec, published by the Alliance for Open Media in 2019. It is the strongest compressor in mainstream use — at comparable visual quality an AVIF is typically around half the size of a JPEG and noticeably smaller than WebP — which is why image-heavy sites and CDNs now serve it automatically to any browser that accepts it.
Support outside the browser is the worst of any modern format. Chrome could display AVIF from 2020 and Firefox from 2021, but Safari only caught up in 16.4 (March 2023), and a great deal of desktop software still opens nothing. Which is how people usually arrive here: an image saved from a modern website, and a machine full of software that refuses it.
Why convert AVIF to JPG?
- You saved an image from a website and nothing will open it. Sites increasingly serve AVIF to browsers that accept it, and right-click-save keeps whatever format was served.
- Upload forms reject it. Portals that grudgingly accept WebP still rarely list AVIF at all.
- Desktop software lags years behind: Photoshop opened AVIF natively only from 23.5 (2022), and Windows Photos needs a Microsoft Store codec extension before it will show one.
- Print services and photo labs require JPEG — AVIF is a web delivery format and has no print workflow.
- JPG is the safest thing to hand to someone else when you do not know what they will open it with.
AVIF compared with JPG
| Attribute | AVIF | JPG |
|---|---|---|
| Compression | AV1 intra-frame — typically around half the size of JPEG at equal quality | DCT, standardised 1992 — larger, but implemented everywhere |
| Support | Chrome 85 (2020), Firefox 93 (2021), Safari 16.4 (2023); still patchy in desktop software | Every browser, operating system and image tool since 1992 |
| Transparency | Yes — full alpha channel, plus animation, HDR and 10/12-bit colour | No — alpha is flattened onto a background colour |
| Metadata | EXIF and XMP (stripped here by default) | EXIF and GPS (stripped here by default) |
| Typical size | ≈100 KB for a 1200×800 photograph | ≈200 KB for the same photo at quality 82 |
What actually changes
Both formats are lossy, so this is a second lossy pass and some detail is discarded permanently. At quality 85 and above the difference is invisible at normal viewing sizes; we default to 82.
Expect the JPG to be substantially larger than the AVIF — often around twice the size. That is not a fault; it is the whole reason AVIF exists, and the target-size mode is there if the result has to fit a limit.
Transparency is lost: AVIF carries a full alpha channel and JPEG does not, so transparent pixels are flattened onto a background colour, white by default. Convert to PNG instead if the transparency matters. An animated AVIF converts only its first frame, and a 10-bit or HDR AVIF is rendered down to standard 8-bit colour on the way through — JPEG has nowhere to put the extra range.
This converter also works in browsers that cannot display AVIF themselves: where native decoding is missing, a WebAssembly decoder is fetched with the page and runs entirely on your device, the same as everything else here.
Frequently asked questions
Why is the JPG so much bigger than the AVIF I started with?
Because AVIF compresses roughly twice as well. A JPEG carrying the same picture at the same visible quality is typically around double the size, and that gap is exactly why the web is moving to AVIF. You are buying compatibility with file size. If the result needs to fit a limit, switch to target-size mode and set one.
My browser cannot even display AVIF files. Will this still work?
Yes. Where the browser cannot decode AVIF natively — Safari before 16.4, for instance — a WebAssembly decoder is fetched with the page and does the work instead. Either way the decoding happens on your device; the file is never sent anywhere.
Will converting AVIF to JPG lose quality?
A little. AVIF is already lossy, so re-encoding to JPEG is a second lossy pass and some detail goes permanently. At quality 85 and above it is not visible at normal viewing sizes. If you intend to edit the image afterwards, convert to PNG instead — every additional lossy save compounds.
The JPG looks flatter or duller than the original. Why?
The AVIF was probably 10-bit or HDR. JPEG holds 8-bit standard-range colour and nothing more, so the extra brightness range is rendered down on the way through. Nothing is wrong with the conversion — JPEG simply has nowhere to put what the AVIF was carrying.
My AVIF is animated. Can I keep the animation?
Not as a JPG — JPEG cannot store animation, so only the first frame converts. If you need the animation, keep the AVIF or use a video format; that is closer to what an animated AVIF already is.
Nothing is uploaded — and you can check
Conversion happens on your own device, inside this browser tab. There is no server to receive your files, which is a stronger guarantee than a promise not to look at them. Open your browser's developer tools, switch to the Network tab, and convert something: you will see no request carrying your image. The page keeps working with your network disconnected.
