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_20210314-144805_Chrome] What am I doing wrong? Here’s our forum if it helps: https://community.morphmarket.com/

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.

This comes up from time to time. There are many times when something is a png for a reason.

I actually want to use PNG… It just won’t allow me. Is there a way to stop the conversion?

[image] Tom_Eagle: Is there a way to stop the conversion? The settings from your screenshot look correct. I’m fairly sure that if you copy/paste a PNG image into the editor, Discourse automatically converts it to a JPG. If that’s how you have been adding the image, try using the editor’s upload button to add the image and see if that makes a difference. I don’t think the image preview jpg quality setting is relavant to the issue, but both the png to jpg quality and recompress original jpg quality settings need to be set to 100 to prevent PNGs from being converted to JPGs. Questions about conversion of PNG images have come up a few times. It would be good to find a way to make the settings that control this behaviour more obvious.

Sorry I should have been more clearer, this is the button I am using to try and change the icon: [Screenshot_20210314-202651_Chrome]

[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).

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