Sprite Sheet Generator - Combine PNGs into One Sprite + CSS

Upload multiple PNG images and generate a single spritesheet PNG plus a CSS mapping. Sprite sheets reduce the number of HTTP requests and can improve performance for icon-heavy interfaces.

Why Use a Sprite Sheet?

  • Fewer Requests: One image file instead of many icons
  • Consistent Styling: CSS classes map icons to correct positions
  • Great for UI Icons: Buttons, menus, badges, and small assets
  • Server-side Packing: Reliable layout and output

Common Use Cases

🧭 Navigation Icons

Bundle menu and toolbar icons for faster rendering.

🎮 UI Sprites

Combine small sprites for games or interactive UIs.

🧩 Component Libraries

Ship a single assets file plus predictable CSS classes.

📦 Landing Pages

Reduce request overhead for icon-heavy pages.
