How to convert AVIF to JPG
- Check the settings under the box. JPG at 92% quality is the starting point; switch to PNG if the image needs to stay transparent.
- Add your .avif files with “Choose AVIF images” or by dragging them in, up to 30 in one go. Conversion starts straight away.
- Save the results one at a time, or all together with “Download all as ZIP”.
What is an AVIF file?
AVIF stands for AV1 Image File Format. It takes the compression from the AV1 video codec and stores the result in a HEIF container: the Alliance for Open Media specification says an AVIF file is “designed to be a conformant HEIF file”. That makes it a relative of the HEIC photos iPhones take, with a different codec inside.
MDN lists lossy and lossless compression, transparency, high dynamic range, 8, 10 or 12 bits per colour, and animation among its features. Websites like it because the files are small. Our guide what is AVIF? explains how it got here.
Which browsers can read AVIF?
This page uses your browser’s own AVIF decoder, so the browser version decides whether it works. These are the first versions with full support according to Can I use, which puts coverage at about 97% of browser use worldwide:
| Browser | Full AVIF support from |
|---|---|
| Chrome | 85 |
| Firefox | 93 |
| Edge | 121 |
| Safari on Mac | 16.4 (16.1 to 16.3 are partial) |
| Safari on iPhone and iPad | 16.0 |
| Samsung Internet | 14.0 |
On anything older, the tool tells you the browser can’t read AVIF instead of failing silently. Update the browser or open this page in a newer one.
Why convert AVIF to JPG?
Websites can publish AVIF safely because they offer a backup. MDN advises them to “provide a fallback in WebP, JPEG or PNG format”. A single file you saved has no fallback, so it runs into every program that can’t read it:
- Photo editors and viewers on older systems may not open it at all.
- Upload forms for jobs, applications and shops commonly ask for JPG or PNG.
- Sending it on: the person receiving it may not be able to view it, whereas a JPG almost always opens.
What changes when AVIF becomes JPG
- Colour depth and HDR. MDN says each JPEG colour component is 8 bits, while AVIF can go to 12 and can store HDR. An ordinary photo looks the same. An HDR photo looks flatter, because its extra-bright highlights have nowhere to go.
- Transparency. JPG has none, so this tool puts a white background behind the image. Choose PNG to keep it transparent.
- Animation. AVIF can hold image sequences, and you get only the first frame.
- File size. Compression is what AVIF does best, so the JPG will generally be larger, sometimes by a lot. Each result lists both sizes.
If the JPG is too big for where it is going, try Balanced quality, or use the image compressor. The image size calculator shows how much data a picture holds at a given number of pixels, and resizing is often the bigger saving. Choosing between newer formats instead? See AVIF vs WebP.
Your images stay on your device
Your browser already knows how to read AVIF, so this page downloads no decoder and sends nothing anywhere. The result holds only the picture, which means any location or camera details in the original aren’t copied across. Keep the AVIF as well if you need those details or the full colour depth later.
