About Sprite Lab
Sprite Lab is a free pixel art editor that runs in the web browser, aimed at making sprites and sprite sheets for games. It works without an account: work is stored in the browser's local storage on the user's device and can be exported as a project file.Drawing tools include a brush and eraser with six tips (round, square, pixel-perfect, dither, spray, crayon), fill with tolerance, shapes, text, and kaleidoscope mirror symmetry with 2 to 20 radii. Selections can be rectangular, freehand or magic wand, and can be moved, scaled, rotated and flipped.
Sprites are organised in folders, and each sprite can hold several named states (for example idle, run, jump). Each state is a strip of frames on layers, with a live animation preview, onion skinning and its own undo history.
PNG and GIF images can be imported, including existing sprite sheets, which are split into frames automatically or read with an Aseprite-format JSON file. Export is to PNG, animated GIF, or one sheet with a row per state plus an Aseprite-format JSON describing the frames, durations and states, which many game engines can read.
The interface works on desktop and touch devices and is available in 130 languages. It suits beginners and game developers who need sprites quickly, for example during game jams.
