The Best Free Sprite Sheet Maker
for Game Developers

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.

What is it?

What is a Sprite Sheet Generator?

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.

Capabilities

Sprite Sheet Creator Features

Everything a game dev needs to pack, trim, preview, and export a professional sprite sheet — right in the browser.

Multiple Layout Modes

Grid, horizontal strip, vertical strip, or packed MaxRects layout — choose what fits your atlas best.

Smart Trim & Extrude

Remove transparent borders automatically and extrude edges to prevent GPU texture bleeding on sprites.

Animation Preview

Play your animation at any FPS before exporting. See exactly how the loop will look in-engine.

JSON Atlas Export

Export TexturePacker JSON Hash or Array formats for Phaser, PixiJS, and Godot atlas text for Godot projects.

No Uploads — Fully Local

All processing happens in your browser. Your art never leaves your machine. No accounts, no limits.

Natural Filename Sort

Frames named walk_2, walk_10 sort correctly — walk_2 comes before walk_10, not after.

Pixel Art Ready

Power-of-two sizing, uniform cell grids, and nearest-neighbor preview for crisp pixel art output.

GIF Frame Extraction

Drop an animated GIF and it'll be auto-split into frames, then packed into a sprite sheet atlas.

Tools

More Sprite Sheet Tools

Four free tools for every step of your sprite sheet workflow — from GIF to atlas to GIF and back.

GIF to Sprite Sheet

Split an animated GIF into frames and pack them into a sprite sheet atlas.

Image to Sprite Sheet

Combine PNG, JPG, or WebP frames into a single sprite sheet atlas.

Sprite Sheet Cutter

Slice a sprite sheet into individual PNG frames with a fixed grid.

Sprite Sheet to GIF

Turn a sprite sheet into an animated GIF for sharing or previews.

Process

How to Make a Sprite Sheet

Four simple steps from your frames to a production-ready sprite sheet atlas your game engine can read.

1

Drop Your Frames

Drag PNG, JPG, or WebP files into the browser window. They'll be sorted by filename automatically.

2

Choose a Layout

Pick Grid, Horizontal, Vertical, or Packed. Set padding, trim, and extrude options to taste.

3

Preview the Loop

Hit Play to see your animation run at your target FPS. Tweak timing before exporting.

4

Export & Import

Download PNG + JSON atlas. Import into Unity, Godot, Phaser, or GameMaker and start animating.

FAQ

Frequently Asked Questions

Common questions about our Sprite Sheet Maker and how to use it with your game engine.

No. Everything is processed entirely in your browser using WebGL and Canvas APIs. Your art files never leave your machine. This applies to all four tools — GIF to Sprite Sheet, Image to Sprite Sheet, Sprite Sheet Cutter, and Sprite Sheet to GIF.
The exported JSON atlas works with Unity, Godot, Phaser, PixiJS, GameMaker, and any engine that reads TexturePacker-style JSON Hash or Array formats. Godot users can export in the Godot atlas text format directly.
Grid lays all frames out in even rows and columns. Packed (MaxRects) fits frames of different sizes into the smallest possible atlas by placing them in gaps — more efficient for mixed-size sprites, but not compatible with engines that need uniform cell sizes like Unity's Sprite Editor.
Trim removes transparent border pixels from each frame before placing it in the atlas. The offset data is stored in the JSON so your game engine can reconstruct the original frame size. This reduces atlas size and improves batching.
Extrude copies the edge pixels of each sprite outward by 1–2 pixels. This prevents GPU texture bleeding artifacts when the GPU filters pixels at the edge of a sprite. Recommended for all production sprite sheets.
Yes. Enable "Power of Two" for atlas dimensions and use the "Uniform Cell Size" option for even grids. When importing into Unity, make sure the texture is set to Point filtering (not Bilinear) to keep pixel art crisp.
Import the PNG into Unity, set the texture type to Sprite, then open the Sprite Editor. Slice the atlas using the Grid By Cell Size option. Unity will automatically create an animation clip from the sliced frames you can drag onto a Sprite Renderer.
