I use Photopea as plugin for Figma and the overall experience is great. The flow feels so natural to be able to quickly jump back and forth between Figma and Photoepa.
It's a solid image editor. It gives you most of the functions that photoshop has, but for free. If you're new to the program it is a little bit hard in use but after a little trying and maybe a tutorial on YouTube you will be able to make your photos/images in to masterpieces!
Photopea.com is my absolute favorite! It's a powerful tool that consistently wows me with its capabilities. A must-try for anyone needing versatile photo editing.
