I use Photopea very often, I love it and purchased a pro-$55 annual subscription, to remove the annoying ads, and also using the AI tools, though. But the BG removal tool is still free. One thing I wanted to point out, is yes, the click Select > Remove BG works, but sometimes it then needs a 2nd time to process correctly. Sometimes that works beautifully, sometimes it doesn't.
Now, say you originally tried the Select > Remove BG, and it removed too much of what you wanted. You can try it twice, and if it still doesn't all you have to do is make sure you're using white/black paints. Then, use your paint tool to brush in white wherever it took too much away. Or, the opposite of this, it didn't automatically remove some background you wanted gone. Take the paintbrush tool, using black color paint and just paint it away. Gray paint is used for fine tuning hairs and such like that.
It's best to know the full process of it, then not being satisfied with simple/fast programs. Because, background removal tools that cost money, start using AI technology to do it, and can be a little bit more accurate, but not 100%. Like, I still pay for Clippingmagic.com for the hardest things I've come across...esp if it's too time consuming or too hard for me. I just thought you'd want to know there are more options within Photopea. And these are just some tricks I've learned.
