Image Sprite Generator
Pack images into a CSS sprite sheet.
Image Sprite Generator is its own job in the catalog (developer): Pack images into a CSS sprite sheet. It is not a copy of the resizer or converter with a new title — the operation is “sprite”.

Questions about this tool
Does Image Sprite Generator upload my file?
No. Processing is in this browser.
Can I use this on a phone?
Yes, with the same file-size cap (about 25 MB). A large photo is slower on a phone CPU than on a laptop.
Does Image Sprite Generator upload the file?
No. This tool runs in the tab. See Privacy for decoder notes (HEIC, PDF.js worker).
What is the file size cap?
About 25 MB per file. Very large pixel counts are rejected so the tab stays responsive.
