Free Online Sprite Sheet Generator

zenlyta's Sprite Sheet Generator helps you combine multiple images into a single sprite sheet — perfect for game development, web icons, and CSS sprites. Upload JPG, PNG, WebP, or GIF images and arrange them in grid, horizontal, vertical, or packed layouts.

No account is required. All processing happens locally on your device using Canvas, ensuring your images remain private.

How to Generate a Sprite Sheet

  1. Select multiple images (2–50) from your device or drag & drop.
  2. Reorder by dragging thumbnails — the order determines sprite positions.
  3. Choose layout: Grid (with columns), Horizontal, Vertical, or Packed.
  4. Adjust padding, spacing, background, and output format.
  5. Click "Generate Sprite Sheet" and preview the result.
  6. Download the sprite sheet PNG/JPG/WebP plus CSS and JSON.

Why Use Sprite Sheets?

Sprite sheets reduce HTTP requests by combining many small images into one, improving load times for websites and games. They also enable efficient animation and icon systems with CSS background-position or JSON frame data for game engines like Phaser and PixiJS.

Privacy-First Image Processing

zenlyta is designed around a client-side, privacy-first architecture. For supported local processing, your images never leave your device.

Frequently Asked Questions

What is a sprite sheet?

A sprite sheet combines multiple small images into a single larger image. It reduces HTTP requests and is commonly used in games and web development for icons and animations. Each sprite's position is defined by x, y, width, and height.

Are my images uploaded?

No. Sprite sheet generation is performed locally in your browser using Canvas. Your images never leave your device.

What layouts are supported?

Grid (auto with columns), Horizontal (single row), Vertical (single column), and Packed (binary tree packing for minimal size). You can adjust padding and spacing for each.

Can I export CSS and JSON?

Yes. The tool generates CSS with background-position for each sprite and JSON with frame coordinates (compatible with Phaser/PixiJS), both downloadable and copyable.

Is this tool free?

Yes, it is free to use without an account on desktop and mobile. No limits on number of sprites (recommended 2–50 for performance).
