What is a texture packer?

A texture packer combines many individual images (sprites) into a single sprite sheet, or texture atlas, plus a data file describing where each sprite sits. Games load one atlas instead of hundreds of files, which cuts draw calls and speeds up rendering.

Is the texture packer free and does it require signup?

Yes, it is completely free with no signup. The packing runs entirely in your browser, so your images are never uploaded to a server.

Which game engines does the output work with?

The exported PNG sprite sheet works everywhere. Data files are available for Phaser, PixiJS, Unity and Godot 4 (.tres), plus generic JSON hash and array formats.

What files do I get when I export?

You get a packed PNG sprite sheet and a data file listing each sprite's name, position, and size, so your engine can slice the atlas back into individual frames. With multi-pack on, each page exports as its own PNG + data file.

Can I add padding or use power-of-two dimensions?

Yes. You can set spacing/padding between sprites, extrude edge pixels to avoid texture bleeding, and constrain the output to power-of-two dimensions for engines and GPUs that require it.
