What is Sign PDF?
A Sign PDF tool lets you add your signature to a document electronically. You can draw your signature with a mouse or finger, type it in a signature font, or upload an image of it, then drag it onto the exact spot on the page. The signature is embedded with pdf-lib in your browser, so signing a contract never means uploading it to a stranger's server.

Frequently asked questions
Is signing here legally valid?+
An electronic signature added this way is widely accepted for many everyday agreements in regions that recognize e-signatures, such as under the U.S. ESIGN Act and the EU eIDAS regulation. For documents that require a certificate-based digital signature or notarization, use a service that provides those specific features.
Is my document uploaded when I sign it?+
No. Your signature is embedded into the PDF entirely in your browser with pdf-lib. The file never leaves your device, which is what makes this safe for sensitive contracts.
How do I create my signature?+
You can draw it with your mouse or finger, type your name in a handwriting-style font, or upload a photo or scan of your handwritten signature.
Can I place my signature exactly where I want?+
Yes. After creating it, drag the signature to any position on the page and resize it so it fits the signature line neatly.
Can I sign more than one page?+
Yes. Place your signature or initials on as many pages as the document requires before downloading the final signed file.
