Upload several small images and combine them into one CSS sprite sheet. The generator creates the final image and CSS positions for each file, so a page can load fewer image requests.
Use it for icons, UI assets, legacy layouts, email templates and small web graphics. Add files, arrange them in the right order, build the sprite and copy the generated CSS.
This tool accepts these formats. Uncommon containers and modern web formats may be normalized or converted on the server before processing.
A damaged file or a non-standard codec can still fail even when the extension is supported.
