PhotoDemon is a photo editor that provides a comprehensive selection of photo editing tools in a very small download. The current build provides more than 200 professional-grade tools, including layers, selection tools and digital paintbrushes, content-aware fill and resize, shadow/highlight recovery, perspective and lens correction, and full support for image files from other popular photo editors, including Adobe Photoshop (PSD), Corel Paintshop Pro (PSP), and GIMP (XCF). An elegant interface built by designers – not engineers – gets out of the way and lets you work. Usability testing drives our design decisions. PhotoDemon comes with a built-in macro recorder and batch processor. Its UI is fully themable, with built-in light, dark, and monochrome themes. All tools support real-time previews, custom presets, keyboard navigation, and unlimited Undo/Redo.
