Turn AVIF files into JPG
Your AVIF goes in and a JPG comes out. JPG is the everyday photo format. One thing to know first: anything see-through in the AVIF comes out on a solid background, white unless you choose another colour. Your file never leaves your computer.

How to convert AVIF to JPG
- 1 Drop your AVIF .avif file onto the page, or click to browse for it.
- 2 Set the quality, or leave the default, which keeps the file small without anything showing.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the JPG, or add more files and do the whole set in one go.
Why convert AVIF to JPG
- You are sending this somewhere that will not keep a transparent background anyway, so putting it on a solid colour costs you nothing.
- Very small files for photos, at a quality that still looks good.
- Opens instantly on virtually every device ever made.
- Photographs on the web and in email.
- AVIF: poor support in desktop image editors and older operating systems.

Quality and what changes
JPG stores the same content under a different set of rules, so what matters here is compatibility rather than picture quality. Convert once from the best source you have rather than through a chain of intermediate files.
- Anything see-through comes out on a solid background, white unless you choose another colour.
- Only the first frame of an animated AVIF is kept.
- One JPG limitation to keep in mind: no transparency: see-through areas come out on a solid colour.
Questions about AVIF to JPG
Will I lose transparency converting AVIF to JPG?
Yes. A JPG cannot hold transparency, so anything see-through comes out on a solid colour, white unless you choose another. If the transparency matters, convert to PNG or WebP instead, and only flatten once you know what the image will sit on.
What happens to an animated AVIF?
JPG holds a single image, so only one frame survives, normally the first. If you need the motion, convert to a format that keeps it such as MP4, WebM or WebP rather than to JPG.
Is my AVIF file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your AVIF is read straight from your own disk, converted on your machine and handed back as a JPG. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several AVIF files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate JPG downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
