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.

Thanks for the details. We probably shouldn’t ever convert PNGs to JPGs when uploading site settings images.

[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 ).

FYI (je suis avec Thomas) concernant notre cas d’usage — cela n’a jamais été un problème pour nous, sauf récemment, car ce JPG a fait planter notre PWA (comme discuté ici).
