Photopea is very good. It is what I recommend to friends who just want an immediate solution.

Photopea is great but I switched to Pixelmator Pro. I just paid $49.99 one time. It's a clean native app. It doesn't install all these horrors of horror on my system like Photoshop did. It doesn't try to pressure me into using some half baked AI tool. (I mean could you imagine what that must be like being an artist who hates AI and Adobe shoves it in your face?) I can't believe I was paying $40/month for Photoshop for so long. Thankfully I got all my money back and more by shorting Adobe's stock. After spending so many years drinking unicorn blood, no software company deserves to fall more. Everyone who invested in them, hoping to get rich off torturing artists and tax payers, deserves to lose their money too.
