@vinceAmstoutz that looks great. Would be great if you could also create a Pull Request for the sulu/skeleton and the sulu/sulu-docs to add the new avif_quality configuration to them:

• https://github.com/sulu/skeleton/blob/2.6/config/packages/sulu_media.yaml
• https://github.com/sulu/sulu-docs/blob/2.x/book/image-formats.rst

@vinceAmstoutz this looks great. Thank you! If possible it would be nice that we create also a test for the getSupportedOutputImageFormats method seems currently that method has no tests yet in the ImagineImageConverterTest.php. Let me know if you have time for that, else I will try to tackle the tests there.

It's done! I just pushed a commit.
