Sprite Sheet Studio

Jobu Studio

About this app

Sprite Sheet Studio is a comprehensive sprite sheet creator that runs directly on your device—no PC required. Import an image, let the app detect and crop the sprites, assemble the sheet, animate it, and export it for use in your game.

Built for game creators: pixel artists and developers using Unity, Godot, Phaser, GameMaker, Construct, and similar engines.

KEY FEATURES
- Import images (PNG, JPG, and animated GIF) and automatically split them into sprites
- Crop using a grid or automatic frame detection
- Remove solid-color backgrounds (chroma key) during import
- Assemble the sheet with custom columns, spacing, alignment, and fixed cell sizes
- Multiple layers for character composition
- Animation preview: playback, FPS, and per-frame duration
- Built-in pixel editor: brush, eraser, eyedropper, and undo/redo
- Recolor tools: hue, saturation, brightness, contrast, and presets
- Export options: PNG (sheet), individual PNGs, animated GIF, JSON (generic, Phaser 3, and Godot), and ZIP
- Choose scale or set fixed width/height for export
- Save and reopen your work using project files (.sfproj)
- Available in 20 languages

WORKS OFFLINE
Everything is processed locally on your device. Your images are never sent to a server.

NO ADS, NO PAID PLANS
The app is completely free, with no advertisements and no locked features. If it helps you, you can support the creator with a donation—though it is entirely optional.

Create animations on the go and take your sprites straight to your favorite game engine.
