What happens, and why

HEIC is the iPhone’s default photo format. Half the size of JPG at the same quality, but Windows and many websites cannot open it. iPhone and iPad cameras have saved in it by default since iOS 11. AVIF applies the AV1 video codec to still images. It is smaller than WebP and opens in current browsers.

Converted to AVIF, the photo opens as is on Windows, on older Macs, and in most websites and office programs. For images going onto a website, AVIF is smaller at the same quality, so the page loads faster.

The file is opened and converted inside this browser and never sent to a server. AVIF is a lossy format, so the image is compressed once at quality 75. The difference is hard to see, but the result is not identical to the source, and the badge next to it says so. Camera metadata (EXIF) is not carried over, so no location data remains in the result. You can add several files at once.

FAQ

3
Does the quality get worse

AVIF is a lossy format, so the image is compressed once. Quality 75 is hard to tell apart on screen, but it is not identical to the source. Quality already lost in HEIC does not come back in any format.

What happens to a transparent background

AVIF stores transparency too, so it is kept as it is.

Where does my file go

Nowhere. The conversion finishes inside this browser, and camera metadata (EXIF, location) is not carried into the result.
