There is no definition for what “quality level” means here and what effect it has, and the old JPEG specification cited, http://www.w3.org/Graphics/JPEG/jfif3.pdf does not define it either (it does not contain the word “quality”). 126057 1 arronei 2016-04-22 21:04:50 +0000 HTML5.1 Bugzilla Bug Triage: Won't fix, quality/compression is actually defined in the specification for JPEG. https://www.iso.org/obp/ui/#iso:std:iso-iec:10918:-1:ed-1:v1:en If this resolution is not satisfactory, please copy the relevant bug details/proposal into a new issue at the W3C HTML5 Issue tracker: https://github.com/w3c/html/issues/new where it will be re-triaged.
