I am in deep need of a good graphics editor for iOS and iPadOS that can handle images that are tens of thousands of pixels in dimension and hundreds of megabytes in size.

Please send help.

I use Pixelmator Pro on the Mac, and their iOS apps can’t do it.

@ablaze Affinity Photo on the iPad should be able to handle that. No Phone version of the app.

@Denny Yep that is what I use on the iPad, but I want it on my phone, and I want to use the same app/project file, ideally on Mac as well, but the mobile use case is sufficiently different that I’ll settle for two apps

@ablaze Guessing you know this but Affinity files on iPad are same format/compatible on the Mac and even Windows. Heck, not only that, but the files can also be opened in any Affinity app natively. So a Photos file on iPad can be opened on Windows using Affinity Photos or Designer or Publisher. So, cross platform and cross app.
