In short: Signing a PDF here means placing an image of your handwritten or typed signature on a page — a simple electronic signature — not a certificate-based digital signature.
About Sign PDF
Printing a form only to sign it and scan it back is slow. This tool lets you draw your signature with a mouse, trackpad, pen or finger — or type your name in a handwriting style — and place it exactly where it belongs on the page.
The signature is embedded as a transparent PNG image with pdf-lib, so the rest of the document is untouched and stays searchable. Your signature and document never leave your device, and nothing is saved after you close the tab.
How to use Sign PDF
- Choose the PDF you need to sign.
- Draw your signature in the pad, or switch to Type and enter your name.
- Pick the page, then drag the signature into position — or tap the spot where it should go, or select it and use the arrow keys — and adjust its width.
- Press Download signed PDF.
Examples
Open the lease, choose the last page, draw your signature and drag it onto the signature line.
Type your name, tick “Add today’s date” and the date is placed under the signature.
Frequently asked questions
Is a drawn signature legally valid?
In many countries, including under the US ESIGN Act and the EU eIDAS regulation, a simple electronic signature can be valid for many documents, but requirements vary. Check what the recipient accepts.
Can I sign several pages?
Download after signing one page, then open the downloaded file and sign the next page.
Is my signature stored?
No. It exists only in this browser tab until you close or reload it.
Does it work on a phone?
Yes. Draw with your finger on the pad and drag the signature with a touch.
