How to make a sprite sheet from icons

  1. 1
    Add your icons

    Choose or drop SVG, PNG, JPG, GIF or WebP files. Add up to 60 images at once.

  2. 2
    Arrange and size the grid

    Drag icons into order, then choose the cell size, padding, columns, fit and background.

  3. 3
    Export the sprite atlas

    Download the transparent PNG and copy its matching CSS classes or JSON coordinates.

When should you use an image sprite?

UI icon collections

Keep a group of small interface icons in one predictable atlas and reference each one with a reusable class.

Games and pixel art

Pack inventory items, badges, tiles or static frames into a uniform grid that is easy to address in code.

Email and legacy projects

Sprites can help when an older environment benefits from fewer separate image requests or a simple shared asset.

Modern web performance

For ordinary websites, compare sprites with inline SVG, SVG symbols and HTTP/2. A sprite still works well for fixed raster icon sets.

Icon sprite sheet generator FAQ

How do I create an icon sprite sheet online?

Add at least two icons, arrange them in the desired order, choose the grid settings and download the generated PNG. Copy the CSS or JSON panel to use the coordinates in your project.

Which image formats are supported?

You can combine SVG, PNG, JPG, GIF and WebP files. Animated GIF and WebP files use the frame displayed by your browser when the sheet is rendered.

Does this online sprite generator upload my files?

No. Your files remain on your device. The sprite sheet and coordinate map are generated with HTML canvas inside your browser.

How does the generated CSS work?

The base class sets the shared PNG as a background image. Each icon class uses a negative background-position to reveal its cell from the complete sheet.

Can my icon sprite sheet have a transparent background?

Yes. Transparent is the default background. Export as PNG to keep transparent areas around each icon.

Should every source icon have the same dimensions?

No. Contain mode scales each icon proportionally inside an equal cell. Similar source proportions usually give the most visually consistent result.
