Convert AVIF to JPG
Drop in your AVIF files and download JPGs. The browser does the decoding itself, so there is nothing to install and nothing to upload.
Conversion happens inside this page using your browser's own image engine. Your files are never uploaded.
How to use it#
- Drop your AVIF files onto the box above, or click it to pick them.
- Set the quality slider to trade file size against detail.
- Download each JPG, or save the whole batch in one go.
Why a JPG rather than a PNG#
If the AVIF is a photograph, JPG is usually the better destination. It keeps the file in the same rough size bracket as the original, while a PNG of the same photo can be ten times larger for no visible benefit.
PNG is the better choice when the image has flat colour, sharp edges or transparency: a logo, a diagram, a screenshot. For anything that came out of a camera, JPG is what the rest of the world expects.
Compressing a photo a second time#
AVIF files are lossy, so the conversion re-compresses an image that has already had detail removed. JPG is also less efficient, which means matching the quality of the AVIF usually takes a noticeably bigger file.
At the default setting a photograph looks the same at normal viewing size. Push the slider up if the picture contains text or fine detail, and down if it only needs to survive as an email attachment.
Transparency becomes white#
JPG has no alpha channel, so any transparent area is filled with white before encoding. That is usually what you want for a picture heading into a document, and it is not something you can undo afterwards.
Use the AVIF to PNG converter instead when the transparency matters, for example a logo that has to sit on a coloured background.
Frequently asked questions#
Are my images uploaded anywhere?
#
No. The decode and the encode both happen in this tab using your browser’s own image engine, so the files stay on your device.
Why can my browser not read the AVIF?
#
AVIF support arrived in browsers around 2021. An older browser cannot decode the file and the row will report a failure rather than convert it. A current Chrome, Firefox or Safari handles it.
Will the JPG be bigger than the AVIF?
#
Usually, yes. AVIF compresses considerably better, so a JPG that looks as good will take more space. Each row shows the measured before and after sizes so you can see the difference for your own file.
What happens to a transparent background?
#
It is filled with white, because JPG cannot store transparency. Convert to PNG if you need the alpha channel kept.
Is camera metadata kept?
#
No. Re-encoding through the canvas discards EXIF data, so the JPG carries no camera model, date or GPS coordinates.
