Sign PDF

Draw your signature (or use a photo of it), click where it belongs on the page, and download the signed document. This places a visible signature image — it is not a cryptographic digital signature.

This tool runs entirely in your browser — nothing you type or open here is ever uploaded. You can disconnect from the internet after the page loads and it still works.
