How signing a PDF works
Add a handwritten or typed signature to a PDF and download the signed file — entirely in your browser, with nothing uploaded.
Your PDF and signature never leave your device; signing happens locally in your browser.
Draw your signature with a finger or mouse, or type your name — then drag it to the right spot and resize it.
The signature is placed as an image on the page you choose, and a new signed PDF is generated for download.
This adds a visible signature image; it is not a certificate-based digital signature. Check whether the recipient requires a certified e-signature.
Frequently asked questions
How do I sign a PDF online for free?
Upload your PDF, draw or type your signature, drag it onto the page where you want it, then download the signed PDF. It’s free with no sign-up.
Is my document uploaded to a server?
No. Both the PDF and your signature stay on your device — signing happens entirely in your browser and nothing is uploaded.
Can I draw my signature or type it?
Both. Draw it with your finger or mouse for a handwritten look, or type your name and it’s rendered in a signature-style font.
Is this a legally binding digital signature?
It adds a visible signature image to the document, which is fine for most everyday forms. It is not a certificate-based (digital) signature, so check whether the recipient requires a certified e-signature.
