AVIF to JPG Converter

Convert AVIF images to JPG in your browser. AVIF packs tighter than JPG, so expect a bigger file, and clear parts take the colour you pick.

AVIF batch converter

Add AVIF files and choose JPG conversion settings.

How good it looks, not how big it gets. 85 looks the same as the AVIF to most eyes.

Makes the image smaller in pixels first. This saves more than quality does.

Reduces the image size in pixels to make the file smaller.

Background

JPG cannot be see-through. Clear parts become this colour.

How it works

  1. 01

    Add your AVIF files

    Drop, paste or pick any number. The files stay in this tab, and the page sends them nowhere.

  2. 02

    Choose the background

    JPG cannot be see-through. Pick the colour that goes behind the clear parts.

  3. 03

    Convert and download

    Save one file, or the whole batch as a zip. Your AVIF files stay as they are.

Expect a bigger file

AVIF is the better format, and that is exactly why the JPG comes out larger. AVIF needs about half of what JPG does for the same picture, so writing the same result as a JPG usually doubles the file. That is not a fault in the conversion. It is the price of a format that everything can open.

And that is the reason to be here. AVIF is new, so older phones, design software, print shops and plenty of upload forms still refuse it. A JPG is read everywhere. If nothing you use has refused an AVIF, you are better off keeping the AVIF you have.

Two things change on the way. Clear pixels have to become a real colour, because a JPG cannot be see-through, so you pick which one. The picture also goes through a second round of loss on top of the one the AVIF already had. At quality 85 that is hard to see. Low numbers stack both sets of marks on the same edges.

Know one more thing before you start. Your browser does the reading. Chrome, Edge, Firefox and Safari 16.4 or newer can read AVIF. On anything older every row will say the file could not be read, and no setting on this page can change that.

Size
Usually larger. AVIF needs about half of what JPG does.
Background
Your pick. Clear pixels become this colour.
Quality
85 by default. A second lossy pass, so keep it high.
Originals
Never touched. Converting always writes a new file.

Frequently asked questions

Why is my JPG bigger than the AVIF?
Because AVIF is much better at packing a picture. It needs roughly half of what JPG does for the same result. A faithful JPG of an AVIF is usually the bigger file, and doubling in size is normal.
Then why convert to JPG at all?
Because a JPG is read everywhere. AVIF is new, and older phones, design software, print shops and plenty of upload forms still refuse it. That is a common reason to convert.
Every file says it could not be read. Why?
Your browser probably cannot read AVIF. Chrome, Edge, Firefox and Safari 16.4 or newer can. On an older browser there is nothing this page can do, because the reading is the browser's job.
Why does a JPG need a background colour?
Because JPG cannot hold see-through pixels and AVIF can. Every clear pixel has to become a real colour. White is the default, since a cut-out logo usually ends up on a white page. Pick black or your own colour when the page behind it is dark.
Does converting hurt the picture?
A little. The AVIF has been through one round of loss already, and the JPG adds a second. At 85 that is hard to see. At 50 the two rounds of marks stack up on the same edges.
What quality should I pick?
Leave it at 85 unless you have a reason. Go to 92 for a photo you will edit again. Drop to 70 only when the file has to be small and the picture is busy enough to hide it.
What about an animated AVIF?
You get the first frame as a still JPG. A JPG holds one frame, so the rest cannot come along.
How many files can I convert at once?
As many as you like. Files run one at a time, so a long queue never holds a stack of decoded images in memory. Your free memory is the only real ceiling.
Do my images get uploaded?
No. Every decode and re-encode happens in this tab. The image data never leaves your device, so there is no copy to delete.
Are my AVIF files changed?
No. Your browser reads each one and writes a separate new JPG for you to download. The file on your disk is untouched.
What happens to EXIF data?
The tool drops it, including the camera and location data. Your browser redraws the pixels on a canvas, and nothing else comes along. The output is tagged sRGB.
Does this work offline?
Yes. Once the page has loaded, converting carries on with no network connection.
