GIMP Image Editor

GIMP (GNU Image Manipulation Program) is a free and open-source raster graphics editor used for image retouching and editing, free-form drawing, converting between image formats, and performing specialized image manipulation tasks. Originally created by Spencer Kimball and Peter Mattis in 1995 at UC Berkeley, GIMP is maintained by the GIMP Development Team and the GNOME project. Key features: image editing (comprehensive raster image editing with support for layers, masks, channels, paths, and selections, supporting common formats including PNG, JPEG, GIF, TIFF, BMP, and WebP). Brushes (customizable paint brushes with dynamics, including pressure-sensitive tablet support, brush spacing, fading, jitter, and color gradient mapping). Color management (full ICC color profile support for professional color workflows including soft proofing and CMYK separation via plugins). Scripting (Script-Fu based on Scheme and Python-Fu based on Python for automating repetitive tasks and creating custom filters and plugins). GEGL (Generic Graphics Library backend enabling non-destructive editing, 32-bit floating point color depth, and high-bit-depth processing for professional workflows). Photo enhancement (perspective clone, heal tool, clone tool, warp transform, cage transform, and seamless cloning for professional photo retouching). Third-party plugins (extensible via community plugins including G'MIC with over 500 filters, Resynthesizer for texture synthesis, and BIMP for batch processing). Customizable interface (dockable dialogs, dark theme, single-window and multi-window modes, and configurable keyboard shortcuts). Animation (basic frame-by-frame animation with onion skinning and frame playback). HiDPI support (full high-DPI display support for retina and 4K monitors). Cross-platform (Linux, macOS, and Windows with native builds and Flatpak distribution).
