What is a sprite sheet maker?
A sprite sheet maker — also written spritesheet maker, and often searched as a sprite sheet generator — stitches individual animation frames into one texture (the “sheet”) plus a JSON atlas that maps every frame's position, size, and trim offset.
Engines love that shape: one draw call instead of dozens, no flicker between frames, and a single file to load. This sprite sheet creator handles the packing job only — it arranges the art you already drew, right inside the browser, so nothing is uploaded anywhere.

Everything a sprite sheet generator should do
✂
Trim, pad & extrude
Cut away transparent borders, add spacing between cells, and extrude edge pixels so filtering never bleeds neighbouring frames.
▦
Grid, strip or packed layouts
Choose a uniform grid, a horizontal strip, a vertical column, or tight bin packing — whatever your engine expects.
⬇
PNG + atlas in one ZIP
Every export ships the PNG sheet, TexturePacker-style JSON, and per-frame images together, ready to drop into a build.
▶
Sprite sheet animation preview
Play the loop at your chosen FPS before exporting so bad frame order, jitter, or a missing frame never reaches the game.
◉
Natural frame ordering
Filenames sort the human way, so walk_2 lands before walk_10 and your animation plays in the order you drew it.
03 · how it works
How to make a sprite sheet in four steps
- 01
Add your frames
Drag PNG, JPG, or WebP frames — or a whole animated GIF — onto the sprite sheet generator.
- 02
Arrange the sheet
Pick the layout, then set columns, padding, trim, extrude, and power-of-two sizing.
- 03
Preview the motion
Play the loop, adjust FPS, and confirm every frame sits where the animation needs it.
- 04
Export for your engine
Download the PNG sheet plus JSON atlas for Unity, Godot, Phaser, PixiJS, or GameMaker.
04 · who uses it
Who uses this SpriteSheet Maker
Indie game developers

Pixel artists
Keep hand-drawn frames crisp. Trimming and alignment are pixel-exact, with no resampling or softened edges.
RPG Maker & engine importers
Need a uniform cell grid to slice inside the editor? Export even cells and import the sheet without guesswork.

06 · FAQ
Sprite Sheet Maker FAQ
What is a sprite sheet maker?
A sprite sheet maker packs animation frames into one image plus metadata, so an engine can play the whole loop from a single texture. Sprite sheet generator, spritesheet maker, and sprite sheet creator all describe the same packing job.
Does this SpriteSheet Maker upload my files?
No. Packing runs entirely in your browser, so frames never leave your machine and there is no account or queue to wait on.
What does the export contain?
A ZIP holding the packed PNG sheet and a JSON atlas describing each frame's position, size, and trim offsets — plus the individual frames if you want them.
Is this a sprite generator that draws characters?
No. This sprite sheet generator arranges frames you already have. It packs art, it does not invent it.
Which engines can read the output?
The TexturePacker-style JSON loads directly in Phaser and PixiJS, Godot reads the atlas text, and Unity's Sprite Editor can slice the sheet by cell size.
Is the Sprite Sheet Maker free?
Yes. The core maker and all four converters are free to use, with no frame cap for local packing.
