Bug ID: 452084 Summary: Krita exported PNG or JPG images are desaturated on social media even if sRGB 8bit is forced Product: krita Version: nightly build (please specify the git hash!) Platform: Compiled Sources OS: All Status: REPORTED Severity: major Priority: NOR Component: Color models Assignee: krita-bugs-n...@kde.org Reporter: gbird...@gmail.com Target Milestone: --- Version: 5.0.2-alpha (git ca4f0c8) (Krita Plus) SUMMARY Before I worked with a sRGB monitor, but recently I switched to a wide gamut DCI-P3 monitor (calibrated) and noticed that my exported PNG and JPG looks washed out/desaturated a bit on Twitter. My first reaction was that Twitter probably uses some crappy conversion to sRGB and I just exported PNG with wide gammut profile attached to it. I tried converting image to sRGB 8bit, but it already was in sRGB profile (the one named Default) and 8bit. Then I tried to use exporter options: "Embed sRGB profile" and "Force convert to sRGB". None of this worked, and the same problem is with JPG. For now the only thing that works is either exporting to WebP for Twitter and for the Instagram convert my PNG using this online tool https://www.online-convert.com/. I also tested it with GIMP and it had the same problem. My guess is that some library that both program use is bundling my monitor ICC to the file even if I manually convert, or force sRGB, and then social media detects it and do their crappy conversion. I attach my PNG JPG and WebP for tests. I also include screenshot how it behaves on my setup. It's a twitter post creation window, on the left is WebP export on the right PNG and JPG. You can see images on the right are a bit desaturated. Extra info. My other software like ImageGlass, Windows Image Viewer or even Paint don't have this problem, only some web based software like Gumroad as well.
