Sprite Sheet Maker — Pack Frames into a PNG Atlas in Your Browser

Free online sprite sheet maker: combine frames, preview the loop, export PNG and JSON

Sprite Sheet Maker: a free in-browser packer for game frames

Sprite Sheet Maker is a browser tool for indie developers, pixel artists, and anyone who already has animation frames and needs one texture a game engine can play. You drop PNG, JPG, or WebP images onto the page, arrange them as a grid or a strip, preview the loop, and download a PNG atlas plus TexturePacker-style JSON. Packing runs in the tab—your frames are not uploaded.

This is a packer, not a character drawing app and not an AI sprite generator. If you need a sprite sheet creator or sprite sheet generator, the job here is the same: take frames you already made and turn them into a sheet.

Core features

• Local processing, privacy first: The sprite sheet maker runs in your browser. Frames stay on your machine.
• Open and pack: No desktop install. Drag files in, sort names naturally (walk_2 before walk_10), reorder, and export.
• Trim, padding, and layout: Cut empty transparent edges, add a little padding, choose grid, horizontal, or vertical layout, and keep the character planted in the atlas.
• Animation preview: Play sprite sheet animation at a chosen FPS and catch a missing or shuffled frame before you export.
• Engine-ready download: PNG plus TexturePacker JSON for Phaser and Pixi; uniform cells for Unity and GameMaker; region text for Godot.

Common tools

• Sprite Sheet Maker: Pack still frames into a PNG atlas with JSON. Start at spritesheetmaker.app.
• GIF to sprite sheet: Split a looping GIF into frames and pack them the same way.
• Image to sprite sheet: Combine a folder of PNG, JPG, or WebP frames into one sheet.
• Sprite sheet cutter: Slice a finished grid back into individual PNGs (same job as a splitter) and download a ZIP.
• Sprite sheet to GIF: Align a grid, preview the loop, and export a GIF to share.

Who is it for?

If you build walk cycles, attack loops, or small UI atlases for Unity, Godot, Phaser, PixiJS, or GameMaker, this site cuts the one-off TexturePacker session. Pixel artists can keep nearest-neighbor preview sharp. Students learning how to make a sprite sheet can follow the on-page steps, then download. You write (or draw) the frames; the tool handles packing, preview, and export.
