Slice a sprite sheet into individual frames, preview the animation and export a ZIP — or pack loose frames into one sheet with a JSON atlas. Pixel-perfect, runs in your browser, nothing uploaded. Free, no account needed.
Two sprite-sheet jobs in one page. Slice: drop a sprite sheet, set the frame size (or grid columns/rows), preview the animation and export the individual frames as PNGs in a ZIP. Pack: drop a set of individual frames and combine them into a single sheet with a chosen number of columns and padding, plus a JSON file with every frame's coordinates.
Works with any pixel-art or hi-res sheet, keeps transparency, and never uploads your art — it all runs on a canvas in your browser. Made for Unity, Godot, GameMaker, Phaser, PixiJS and hand-rolled engines.
The sheet size and, for every frame, its filename plus x, y, width and height — the same information most engines' atlas importers expect.
Yes. Frames are copied pixel for pixel with no smoothing or resampling.
No. Slicing and packing run on an HTML canvas in your browser.
