Free Picture Editing Online

Many art teachers are  frustrated with expensive photoshop subscriptions and crappy alternative programs. Gimp can be used for free,  but the panel design is confusing for the kids and the program is freezing and crashing too often.

Also, students have devices with different operating systems (Windows, Android, Apple), so how to find a free picture editing program, which works for all?

The solution are free online browser-based editing programs like Photopea and PixlR
