Photopea opens PSD files, edits layers and masks, applies filters, and exports to multiple formats — all without installing anything. It runs entirely in the browser, and your files never leave your device. The interface will look familiar to anyone who has used Photoshop, with panels for layers, channels, paths, and history. It supports not just PSD but also XCF, Sketch, XD, Figma, and RAW formats from most camera brands.

For quick edits, background removal, or preparing images for the web, it covers more ground than most people expect from a free tool. There are no watermarks and no file-size limits. It is particularly useful on machines where you cannot install software, or when you need to open a PSD on a borrowed computer. Many people find they never need to buy image-editing software after discovering it.
