How to convert AVIF to JPG
- Drop in your images. Supported image formats can go in together — there is no need to sort them by format first.
- Tick the ones you want in this round. Everything you add starts selected; untick anything you want to skip.
- Choose Export as — it starts on JPG. Quality and the background colour are next to it.
- Press Export. One file downloads directly; two or more arrive as a single ZIP.
Your files stay in the workspace after an export. Change the selection, switch the output format, and export again — you never re-upload.
Why move an AVIF to JPG
AVIF is a newer image format, and the reason people reach for this conversion is almost always the same one: something they need to use the picture in will not open it. Older photo software, print shops, upload forms with a fixed list of accepted extensions, and plenty of devices that are only a few years old still expect a JPG.
JPG is the opposite trade. It is old, it is lossy, and that is exactly why it is accepted nearly everywhere. If the file is going to be sent to someone else, attached, printed or uploaded, JPG is the safe thing to hand over. If it is only going to sit on your own disk and you can open it, there is no reason to convert it at all.
Transparency has to become a colour
- Quality is a real setting here, not decoration. Lower numbers give a smaller file and more visible artefacts.
- Background only does anything when the image actually has transparent pixels.
- Exporting the same files twice at two different quality settings is fine — nothing is consumed by an export.
JPG has no transparency channel at all. An AVIF that has transparent areas cannot keep them in a JPG, so they have to be filled with something, and the honest version of that sentence is: you choose what.
The colour sits next to Export as as Background. It starts on white and black is the other option; whichever one is selected when you press Export is what gets painted behind the image. Fully opaque AVIF files are unaffected — there is nothing to fill. If keeping the transparency matters more than compatibility, export as PNG instead: it is in the same dropdown.
What this page supports
- Input: AVIF — plus JPG, PNG, WebP and BMP if you want to mix them into the same batch.
- Output: JPG by default; PNG and WebP are one dropdown away. AVIF itself cannot be exported here — it is a format this page reads, not one it writes.
- Transparency: flattened onto the selected background colour, because JPG cannot store it.
- Metadata: EXIF, ICC colour profiles, GPS coordinates and capture dates are not carried over. Keep the original file if you need them.
- Batch: files are processed one at a time so memory stays predictable; duplicate output names are numbered automatically.
- Size: no fixed limit is imposed. The practical ceiling is your device's memory.
Reading an AVIF is something your browser does, so a browser too old to decode the format will mark those files as failed. If that happens, the rest of the batch still converts — one file that cannot be read does not stop the others.
Questions
Are my images uploaded?
No. Everything happens inside your browser tab: files are read from disk into memory, redrawn, and re-encoded locally. Nothing is sent to a server, and there is no server-side copy to delete afterwards. You can watch the network panel while you convert — it stays quiet.
Will the JPG look the same as the AVIF?
Close, but it is a re-encode rather than a copy, so it is not identical. The image is decoded, drawn, and written again as JPG — a lossy format — so fine detail changes slightly, and more so at low quality settings. Start at the default and only lower it if you need a smaller file.
Why is my JPG bigger than the AVIF?
Because AVIF was designed much more recently and usually compresses photographs harder than JPG does at a similar appearance. Getting a larger file is the normal outcome of this conversion, not a sign of anything going wrong. What you are buying with those extra bytes is compatibility.
What happens to transparent parts of the image?
They are filled with the colour selected under Background — white to begin with, or black. JPG has no way to store transparency, so it has to become a solid colour. Export as PNG if you would rather keep it.
Can I convert a JPG back to AVIF here?
No. This page reads AVIF and writes JPG, PNG or WebP; there is no AVIF output. If you need a smaller file than JPG and the software at the other end can handle it, WebP is in the same dropdown.
Can I convert a whole folder at once?
Yes. Add as many files as you like, tick the ones you want in this round, and export — one file downloads directly, two or more arrive as a single ZIP. Your files stay in the workspace afterwards, so you can change the selection or the output format and export again without re-adding anything.
