Pack your PNG, JPG, or WebP frames into a sprite sheet atlas — no uploads needed. Trim, pad, extrude, preview animations, and export PNG + TexturePacker JSON in seconds.
A Sprite Sheet Generator (also called a SpriteSheet Maker) packs multiple individual frames or images into a single texture atlas — the sprite sheet. Sprite sheets are the industry-standard way game engines like Unity, Godot, Phaser, and GameMaker handle animation.
Instead of loading dozens of separate image files, your game loads one PNG atlas plus a small JSON metadata file. This reduces HTTP requests, improves GPU texture batching, and makes animation playback fast and predictable. Our Sprite Sheet Maker does all of this entirely in your browser — nothing is uploaded to any server.
Everything a game dev needs to pack, trim, preview, and export a professional sprite sheet — right in the browser.
Grid, horizontal strip, vertical strip, or packed MaxRects layout — choose what fits your atlas best.
Remove transparent borders automatically and extrude edges to prevent GPU texture bleeding on sprites.
Play your animation at any FPS before exporting. See exactly how the loop will look in-engine.
Export TexturePacker JSON Hash or Array formats for Phaser, PixiJS, and Godot atlas text for Godot projects.
All processing happens in your browser. Your art never leaves your machine. No accounts, no limits.
Frames named walk_2, walk_10 sort correctly — walk_2 comes before walk_10, not after.
Power-of-two sizing, uniform cell grids, and nearest-neighbor preview for crisp pixel art output.
Drop an animated GIF and it'll be auto-split into frames, then packed into a sprite sheet atlas.
Four free tools for every step of your sprite sheet workflow — from GIF to atlas to GIF and back.
Split an animated GIF into frames and pack them into a sprite sheet atlas.
