Embed Free Tools on Your Website

Pick a tool, copy the snippet, paste it into your page. The widget loads in an iframe, sizes itself to its content automatically, and follows either your visitor's system theme or one you choose. Nothing is uploaded — an embedded tool runs in your visitor's browser exactly as it does here.

Embedding is free and the widget carries a small attribution link back to this site. Only client-side tools can be embedded; the few that process files on our server are excluded.
