When I post a gif here on meta it gets converted to jpg. This happens both when I upload it directly, or simply post a link to one:
This is certainly a feature.
See the png to jpg quality site setting. You can disable by setting png to jpg quality to 100
Hmm but this is a gif, not png?
We probably need to fix the site setting name here, cc @nbianca ⌠also we should only apply this to non animated gifs.
Confirmed this is removing animated gifs as they are posted.
I changed setting png to jpg quality to 100 and itâs still turning animated gifs into jpgs
Same. I tried changing recompress original jpg quality and image preview jpg quality to 100 to disable them as well without success. Fixing this will likely require a code change methinks (which Iâm sure theyâre working on now).
This was merged in about an hour ago (complete with a typo in the commit message).

The merge includes a test to ensure we donât attempt to modify animated images in the future. It will require an update to your Discourse instances to pick up the changes.
