What this tool does
Choose an AVIF, set the quality, and download a JPG. This helps when an editor, form, email client or older system can’t open AVIF, a common situation since many sites now serve images in that format.
How to use it
- Choose a AVIF file, or drop it on the page. A preview and its size appear.
- Set the quality with the slider. It starts at 85%.
- Press Convert to JPG.
- Compare the input and output sizes the page shows, then press Download JPG.
Where it runs
The work happens in your browser, using the canvas feature that every current browser has. The image is not uploaded and nothing is stored on this site’s server.
Your browser has to be able to open AVIF to read the file. Current Chrome, Edge, Firefox and Safari 16.4 and later can. If yours can’t, the tool reports that it couldn’t read the image.
Notes on the conversion
- Transparent areas are filled with white, because JPG has no alpha channel. There is no colour option.
- Choose 85 or above if you want to stay close to the original look.
- A JPG will usually be bigger than the AVIF, sometimes much bigger. That is the price of wider compatibility.
- Each conversion is a new lossy encode, so don’t convert back and forth. Keep the AVIF as your master.
- High bit-depth or HDR images are flattened to standard 8-bit colour, so their look can change.
Limits
- JPG can’t hold transparency. Transparent areas are filled with white. There is no option to choose another colour.
- Metadata such as EXIF, location and colour profiles is not carried over, because the image is redrawn.
- Browsers apply a photo’s EXIF rotation when they open it, so a phone photo normally comes out the right way up.
- An animated image becomes a single still frame.
- The page states a 20 MB maximum but doesn’t check it in the browser. Very large images depend on your device’s memory, and the browser can fail on huge ones.
If you need transparency, use AVIF to PNG instead.
Why is the JPG bigger than the AVIF?
AVIF compresses more efficiently than JPEG, so the same image takes more space as JPG.
What happens to transparent areas?
They are filled with white.
Can it convert HDR AVIF files?
It outputs standard 8-bit JPG, so HDR images will look different.
Why does conversion fail?
Your browser may not be able to open AVIF, or the file may be damaged.
Is my AVIF uploaded?
No. The browser decodes it and the JPG is created on your device.
