I use Moho Studio on macOS to create an icon and a launch screen for my iOS application. But when I right click on the exported png file then I can see that the color profile is missing. I have tried to add this png file to Assets-->AppIcon image set in Xcode and I got no error message because the color profile is missing. My png file looks like this:

Is it possible to use png files even if they don't have the color profile sRGB IEC61966-2.1? Is it possible that the images won't display correctly on an iOS device because the color profile is missing? I cannot add the color profile in Moho Studio. I would need another program if it is necessary to add the color profile to the png files. Which program should I use if I need to add the color profile to my Moho Studio png files?

I believe that sRGB IEC61966-2.1 is “normal” sRGB, which is surely the default for PNG files.

I’m sure it will be fine. If the icon looks right when, for example, you see it on the App Store Connect web interface, then it will look OK on the devices.
