GIMP (GNU Image Manipulation Program) is a free, open-source, cross-platform raster image editor: layers, masks, filters, PSD support, and a customizable workspace with a large plugin ecosystem.
Completely free, no subscription, no trial countdown, no watermark, usable for personal or commercial projects indefinitely.
Designers and hobbyists who want a full-featured Photoshop alternative with zero cost, and are comfortable with a less polished but highly extensible interface.
PSD file support means GIMP can open (though not always perfectly preserve) Photoshop files, useful as a free fallback when full Photoshop access isn't available.
