Convert AVIF to JPG
Saved an image from a website and got an .avif file nothing accepts? JPG is the universal answer — every app, form and device takes it. The tool decodes your AVIF exactly and re-encodes at quality 90 by default, which keeps the conversion visually transparent. Transparent regions get a white background, since JPG has no alpha.

How it works
Drop the stubborn .avif files here; each decodes locally and re-encodes as a JPEG at quality 90.
Watch for transparency — JPG flattens it onto white, so cutouts and stickers may deserve the PNG route instead.
Lower the slider only if size pressure demands it, then take your universally accepted files singly or as one zip.
AVIF vs JPG
Head to head, AVIF is technically better in every measurable way except one: the places that accept it. JPG converts that single advantage into the win whenever a file must clear an upload form, an inbox or a print counter — and at quality 90 nobody will spot the difference.
| AVIF | JPG | |
|---|---|---|
| Compression | Lossy or lossless | Lossy |
| Transparency | Yes (full alpha) | No |
| Animation | Yes (rarely used) | No |
| Support | All current browsers (Safari since 16.4, 2023) | Universal — the safest format there is |
| Best for | Hero images and photo-heavy pages | Photographs and strict upload forms |
Frequently asked questions
No — that is the whole reason I built this. The conversion runs in your browser using WebAssembly, so your files never leave your device; there is no server in the loop at all. It also means the tool keeps working offline once the page has loaded, and there is no file size limit beyond your device’s memory.
At the default quality 90, yes — you will not see a difference. The JPG will be noticeably larger than the AVIF was, because JPEG is a far less efficient format. That is the price of universal compatibility.
JPG cannot store an alpha channel, so transparent areas are composited onto white. If the transparency matters — logos, stickers, cutouts — use AVIF to PNG instead.
Bandwidth. AVIF is roughly half the size of JPEG at the same quality, so large sites serve it to every browser that advertises support. Your browser accepts it happily — it is the rest of your software that has not caught up.
JPG is the compact, works-everywhere exit: quality 90 looks identical for photos and every form accepts it. PNG is the faithful exit: exact pixels, alpha preserved, much larger file. Photos and screenshots of photos → JPG. Logos, transparency, images you will edit → AVIF to PNG. Getting this choice right matters more than any quality slider.
Whenever it only lives on your own site: converting to JPG roughly doubles the bytes for zero visible gain, which is paying compatibility tax without needing the compatibility. Convert at the moment of friction — an upload form, a client on old software, a print shop — not preemptively.
