So we messed up our “manifest icon” a while back and now we are unable to upload a PNG file to fix our API problem. Whenever I upload a Png it auto converts it to Jpg. I have tried all three of these settings in hopes of finding a solution but nope… Nothing seems to work! [SmartSelect_20210314-1…

Use TinyPNG to reduce the size of the PNG icon will fix the problem. I have the same problem before, I spent hours to debug and searched for solution. Finally I found out that it was caused by the size of the icon. Reduce the PNG size (by reduce resolution or bit depth) will fix the problem.

[image] simon: We probably shouldn’t ever convert PNGs to JPGs when uploading site settings images. I agree with this, @techAPJ is this a change you can make? Appears to have happened to quite a few admins already.

FYI (I’m with Thomas) regarding our use case – this has never been an issue for us except recently, because this JPG broke our PWA (as discussed here ).
