Try Photopea, a Free Photoshop Clone in Your Browser
For those familiar with Photoshop, you'll feel right at home with Photopea, a photo editing solution that has many of the same basic tools as Photoshop but runs in your internet browser window.
Using Photopea, you can open and edit PSD, XCF, Sketch, XD, CDR as well as popular image file formats and save them as PSD, JPG, PNG or SVG files. And yes, it supports layers and masks.
I must admit to being very skeptical when I was first introduced to this in-browser editor, but it didn't take long for me to be impressed by its functionality and design.
Of course, it's not as full-featured as Photoshop CC, but it's still one of the coolest things I've seen in a while.
I highly suggest you bookmark the page and keep it handy for those times you need to do some quick editing on a machine where Photoshop isn't (or otherwise can't be) installed. [Sean]
