Photopea is a web-based image editor that runs entirely in the browser, allowing users to edit photos and create graphics without installing software. It supports both raster and vector editing and can open and save industry file formats including PSD, AI, and Sketch. Photopea exposes familiar layer-based editing, text, filters, and selection tools similar to desktop photo editors, and is accessible for free with community and GitHub-driven support channels. Its combination of wide file-format compatibility, no-install convenience, and Photoshop-like interface makes it a practical alternative for users who need fast, cross-platform image editing.
