What RetroSprite is

RetroSprite is a free Windows pixel-art editor and animation tool built with Python. It is intended for pixel art, sprite sheets, tilemaps, and frame-by-frame animation. Fourteen drawing tools include symmetry modes, pixel-perfect lines, dithering, and tiled drawing. Text supports bitmap fonts, custom TTF or OTF fonts, adjustable letter spacing, and multiline layouts. Rectangle, magic-wand, lasso, and polygon selections can be rotated, scaled, or skewed. Animation work includes unlimited layers, blend modes, layer groups, non-destructive effects, onion skinning, frame tags, and forward, reverse, or ping-pong playback. Tilemap features provide reusable palettes, pixel and tile editing, canvas sampling, and tile thumbnails with flip controls. Projects use the .retro format; exports include PNG, GIF, WebP, APNG, sprite sheets, and frame sequences. Imports include Aseprite and Photoshop PSD files. Plugins, a scripting API, and command-line mode support custom tools, effects, batch operations, and headless export. Source installation requires Python 3.10 or newer plus Pillow, NumPy, imageio, and Tkinter. The project is licensed under GPLv3 or later.
