Sprite Sheet Maker
Turn frames or GIFs into one engine-ready sprite sheet: edit the timeline, pack tight or on a grid, and export data for Phaser, Godot, Aseprite and more. Free, no signup.

Sprite Sheet Maker, step by step
- 01
Add frames
Drop several PNGs at once (sorted by name), an animated GIF, or both. Add more any time; frames are appended.
- 02
Edit the animation
Reorder, duplicate or delete frames and set each frame’s timing. The preview plays exactly what you will export.
- 03
Lay out the sheet
A same-size grid for simple engines, or tight MaxRects packing with trim, padding and edge extrusion against texture bleeding.
- 04
Export for your engine
The sheet PNG plus data for TexturePacker, Aseprite, Phaser 3, Godot 4 or CSS, with frame timing, tag and pivot.
Generate real pixel art from a prompt
Retro Diffusion's models draw on a true pixel grid with a limited palette: characters, tilesets, animations and more, from $0.03 an image. New accounts start with free balance.
Sprite Sheet Maker FAQ
Select all the frame PNGs and drop them in together. They are sorted by name (frame-2 before frame-10), shown in a timeline you can reorder, and packed into one sheet with a data file describing every frame.
A grid keeps every frame in a same-size cell, which suits Godot hframes/vframes, Unity grid slicing and Aseprite imports. Packed (MaxRects) trims empty space and fits frames tightly, which suits atlas loaders like Phaser, PixiJS and TexturePacker readers.
When a game scales or filters a sprite, the GPU can sample a pixel or two outside the frame. Padding leaves a gap between frames; extrude repeats each frame’s edge pixels into that gap, so nothing bleeds in.
TexturePacker JSON (hash or array) is read by Phaser, PixiJS, Cocos and most frameworks. The Aseprite export keeps frame timing and the animation tag, Phaser 3 gets an atlas plus an animation config, and Godot 4 gets a ready SpriteFrames resource.
