AVIF to JPG makes modern web images open in older applications and upload forms that do not support AVIF yet. Expect a slightly larger file, because JPG compresses less efficiently.
AVIF compresses better than WebP and JPG, which is why image-heavy sites have started serving it. The catch is support: older Photoshop versions, Windows photo viewers and many upload forms cannot open it.
This tool decodes AVIF using the browser’s native decoder and re-encodes to JPG, all on your device.

Why convert AVIF?
Desktop apps refuse it
AVIF support only arrived in Photoshop 23.5 and recent OS releases.
Upload forms reject it
.avif is rarely on the accepted-format list.
Sharing
JPG works in every chat app, email client and printer.

How AVIF compares with the alternatives
| Format | Size at matched quality | Browsers | Desktop apps |
|---|---|---|---|
| AVIF | Smallest — the baseline here | Chrome 85+, Firefox 93+, Safari 16.4+ | Photoshop 23.5+ and recent OS releases only |
| WebP | 10–30% larger | Every current browser | Patchy |
| JPG | 25–50% larger | Everything | Everything |
| PNG | Five to ten times larger | Everything | Everything |
AVIF is AV1 inside a HEIF box
AVIF reuses the ISO/IEC 23008-12 container — the same box structure as HEIC — and swaps the codec inside for AV1. Both files are ISO BMFF: a series of typed boxes, with the brand in the `ftyp` box telling software what it is looking at. That shared ancestry is why a `.avif` and a `.heic` can be the same size and still behave completely differently in the same application.
AV1 compresses better than VP8 (WebP) and considerably better than JPEG, which is why image-heavy sites have started serving AVIF first and falling back to WebP and JPG. The cost is decode complexity — cheap enough now that every current browser handles it natively, but expensive enough that encoding AVIF in a browser tab is still rare, which is why this tool converts in one direction only.
Support is where AVIF loses. Photoshop only gained it in version 23.5, Windows needs the optional AVIF Image Extension before Explorer will draw a thumbnail, and most upload forms have never heard of the format. The file is technically superior and practically unopenable, which is the same problem HEIC has.
One conversion detail matters for quality: AVIF can carry 10-bit colour and HDR, while the JPG this tool produces is 8-bit SDR. A well-exposed photo converts cleanly; a deliberately HDR image will look flatter, and smooth gradients can band. That is a property of JPEG, not a fault in the conversion.
If the conversion will not run
AVIF decoding is done by the browser itself, not by a library this site ships — so browser version is the usual answer.
| Symptom | What causes it | What to do |
|---|---|---|
| "This browser cannot decode this format" | The browser predates AVIF support and there is no built-in fallback | Update to Chrome 85+, Firefox 93+ or Safari 16.4+ |
| The JPG looks flatter than the original | HDR or 10-bit source tone-mapped into 8-bit SDR | Expected. JPEG has no way to store the extra range |
| Gradients show visible bands | 8-bit output of a 10-bit source | Convert at quality 95, or keep the AVIF for display |
| The file is named .avif but nothing opens it | Some sites serve AVIF bytes under a .jpg name, or the download was truncated | Re-download; if it still fails, the file may not be AVIF at all |
| Only the first frame of an animation appears | JPG holds a single frame | Export the animation as video or GIF instead |
Where AVIF is still rejected
Useful before you send a converted file back out — or before you decide to keep the original.
| Destination | Accepts AVIF? | Note |
|---|---|---|
| Windows 11 Photos and Explorer | Only with the AVIF Image Extension | A free Store package, separate from the HEVC one |
| Photoshop before 23.5 | No | Update, or convert first |
| Gmail and Outlook preview | No | The attachment arrives but will not render inline |
| Most upload forms | Rarely | .avif is usually missing from the accepted list |
| Instagram, Facebook, X | Yes, then re-encoded | The platform decides what it serves afterwards |
| Print shops | Rarely | Ask for JPG or TIFF |
If you control the site, serve AVIF first and keep a WebP or JPG fallback in a `<picture>` element — you get the size win without the compatibility problem.
Questions
Why can’t my computer open AVIF?
AVIF is recent; older operating systems and applications simply lack a decoder.
Does my browser support AVIF decoding?
Chrome 85+, Firefox 93+, Safari 16.4+ and Edge 121+ can decode AVIF. If yours cannot, the tool will show an error instead of failing silently.
Can I convert JPG to AVIF here?
Not yet — encoding AVIF in the browser is slow and poorly supported.
Is AVIF better than JPG?
On file size and colour depth, yes — typically 25–50% smaller at matched quality, with 10-bit and HDR support. On compatibility it is worse than every other format on this site.
Does converting AVIF to JPG lose quality?
One pass of re-encoding at quality 92 is visually indistinguishable in normal viewing, but it is lossy and it discards the 10-bit/HDR range. Convert from the original, once.
Why can I see an AVIF in my browser but not in Photoshop?
Browsers bundle their own AV1 decoder. Desktop applications rely on the operating system or ship their own, and many still do not include one.
