I used ImageMagick [0] just now to create a couple test images.

Imagemagick that's packaged in Debian doesn't have avif support unfortunately. They somehow split between version 6 and version 7 which is confusing, because both are progressing in parallel but they don't have feature parity.

I can try getting version 7.

Ah, I didn't realize that! Looking at this [0] issue thread, it seems like the minimum version with AVIF support is v7.0.25. The suggestion to use Docker in that thread might be useful for you as well, if you are interested in a couple quick tests and are already set up for containers.

I wouldn't recommend using anything in the debian repos if you want a feature newer than 5 years old.

I don't have this problem normally, because I'm using Debian testing, not Debian stable. There is a major difference.

Also, the difference between imagemagick 6 and 7 isn't simply about being an older version.

Arch Linux, AUR, etc, tryuck Plebian!

Are you talking about "stable" repos? Do you know anyone who sticks to those, for personal use?

(A lot of people use "testing" for reasons I have not been able to comprehend. The main difference from "unstable" is it takes a minimum of 2 weeks for fixes to show up in "testing". Or did, last I checked.)

Breakage happens less in testing. That's the main reason I'm using it vs Sid.
