How to use the AVIF to JPG converter
- Drop the saved AVIF pictures onto the page.
- Pick a quality; 85–90 matches the original closely.
- Set a fill colour under More settings if any image has transparent parts, then convert and download.
Decoding that works in more browsers
AVIF is the still-picture form of the AV1 video codec. Your browser decodes it when it can; when it cannot, a WebAssembly AVIF decoder is fetched instead, so the conversion still works on older setups. MozJPEG then writes a progressive JPG.
HDR AVIF images are brought down to standard 8-bit sRGB, which looks like a normal photo but does not keep the extra highlight range.
Why the JPG is larger
AVIF is unusually efficient, so the JPG version is typically two to four times bigger at quality 85–90. Lowering quality closes some of that gap; below about 70 the JPG starts to show blocking the AVIF never had.
Transparent areas are filled with the colour you choose, since JPG has no alpha channel. AVIF to PNG keeps transparency if you need it.
A folder of downloads at once
Drag in a whole folder of saved AVIF pictures and they are queued together, each row showing its old and new size. The ZIP button bundles the finished JPGs into one download.
Because the files are never sent anywhere, it is safe to use on unpublished artwork, screenshots of private dashboards or pictures a client shared with you.
Questions
What about animated AVIF?
You get a still of its opening frame. Moving AVIF clips belong in a video converter.
Are the files sent anywhere?
No. Decoding and encoding both happen in this tab, so private images stay on your machine.
Which quality should I choose?
Start at 90 for artwork you might print or edit again. For pictures that will only be viewed on screens, 75–80 keeps the JPG noticeably smaller and still looks clean.
