Sprite Sheet Generator
Drop in your frames and get back a packed sprite sheet with the atlas metadata your engine expects. Free, no account, and nothing leaves your browser.
This is the same packer built into our sprite sheet maker studio — the part that turns loose frames into something Unity or Godot can play.
Pick the frames of one animation. This sprite sheet generator packs them in your own browser — nothing is uploaded.
What this sprite sheet generator does
A sprite sheet packs every frame of an animation into one texture on a uniform grid. Engines then draw a single rectangle per frame instead of loading dozens of files, which is why nearly every 2D pipeline expects one.
Packing is the easy half, and most tools do it. The half that wastes an afternoon is the metadata: the rectangle for each frame, the pivot, the frame rate, in whatever shape your engine reads. This generator writes that for you, for Unity and Godot both.
Frames of different sizes are padded onto one grid, bottom-aligned so characters keep their footing. Nothing is uploaded — the packing runs on your own machine.
Need the frames themselves?
If you have one character image and no animation yet, the studio generates the in-between frames, aligns them so the character does not drift, and lets you drop any frame you do not want before it packs the sheet.

Is this sprite sheet generator free?
Yes, and there is no account. Your frames are packed in your own browser — nothing is uploaded to a server, so there is no queue, no watermark and no upload limit beyond what your machine can hold.
What is a sprite sheet?
A sprite sheet is a single image holding every frame of an animation laid out on a uniform grid — which is what a sprite sheet generator builds for you. Game engines load one texture and draw a rectangle from it per frame, which is far cheaper than loading dozens of separate images.
My frames are different sizes. Will it still work?
Yes. Unlike a naive sprite sheet generator that refuses mismatched input, frames are padded onto one uniform grid before packing, bottom-aligned and horizontally centred, so a character standing on the ground stays on the ground instead of appearing to hover.
What does the download contain?
The sprite sheet PNG, a TexturePacker-style JSON that Unity, Phaser and PixiJS read directly, a Godot 4 SpriteFrames .tres resource, and a neutral atlas descriptor if you load sheets yourself.
Can it generate the animation frames for me?
Not this page — this one packs frames you already have. If you have a single character image and need the in-between frames created, that is what the studio does.
