devbranch.Changelog Entry
Description
The jpeg compression quality for new avatar image uploads is adjusted down to 0.15 (used default before), which is enough to prevent significant visible artifacts and significantly reduces the base64 encoded image string that is written to the user's row in the user table. This prevents unnecessary database size and should only help performance, if anything.
Changed
Additional Information
Existing avatars are not changed, they would have to be reuploaded to be affected.
For the following testing image from https://upload.wikimedia.org/wikipedia/commons/f/fd/Angela_Merkel_%282008%29.jpg
the resulting base64 string was (~32kB)
before and now is (~4kB)
Going lower in quality (e.g. 0.1) would further reduce size but then you start seeing artifacts if you look closely.
