About

About Texture Packer

Free Texture PackerSprite Sheet GeneratorSprite Sheet Maker

Sprite sheet generator: turn images into one sheet

Add loose PNG, JPG or WebP sprites, or select a folder of animation frames, and the packer arranges them into a single sheet. Folder names can be kept in the sprite names, so a walk cycle stays grouped as walk/01, walk/02 and so on.

The preview shows exactly where every sprite lands and how much of the sheet is used, before you export anything.

Texture atlas maker with engine-ready exports

Pick the exporter for your engine and the packer writes the matching data next to the atlas PNG: Unity (native import, TPSheet or JSON), Godot, Unreal, MonoGame, Pixi, GameMaker, O3DE, Construct 3, Phaser, Cocos JS, Cocos Creator, CSS sprites or generic JSON.

Set the maximum size up to 4096 × 4096, keep it a power of two if your target needs it, and turn on multipack to split a large set across several numbered sheets.

Sprite packer settings that save texture memory

Trimming removes empty transparent borders so sprites pack tighter, rotation lets the packer turn sprites to fill gaps (where the chosen exporter supports it), and padding and extrusion stop neighbouring sprites bleeding into each other when the engine filters the texture.

A tighter sheet means fewer texture swaps and less memory in the game, which matters most for mobile and web builds.

A free alternative to desktop texture packers

There is nothing to install and no licence key: open the page, pack, and download. That makes it handy for a quick atlas on a machine without your usual tools, or for teammates who only pack sheets now and then.

Your sprites are processed by your browser and never sent to a server, so unreleased game art stays on your computer.

Is this texture packer free?

Yes. Packing, preview and export are free, with no account and no watermark.

Can I use it as a sprite sheet generator for animation frames?

Yes. Add the frames or their folder, and the packer builds one sheet plus a data file that lists every frame for your engine.

Do I need to download TexturePacker or another app?

No. It runs in your browser on Windows, macOS and Linux, so there is nothing to install.

Which game engines can I export for?

Unity (native import, TPSheet and JSON), Godot, Unreal, MonoGame, Pixi, GameMaker, O3DE, Construct 3, Phaser, Cocos JS, Cocos Creator, CSS and generic JSON.

Are my sprites uploaded to a server?

No. Packing, preview and export all happen in your browser, so the images stay on your device.

What is the largest atlas I can make?

Each sheet can be up to 4096 × 4096 pixels; turn on multipack to spread a bigger set across several numbered sheets.

Can it make a texture atlas for Unity or Phaser?

Yes. Choose the Unity or Phaser exporter and the atlas downloads with the data file that engine imports directly.
