About the Sign PDF
Lets you draw a signature and place it onto any page of a PDF, at the position and width you choose.
Freelancers and small business owners use it to sign a contract or invoice without printing and scanning anything, while anyone approving a document remotely uses it to add a personal signature in seconds. It's one of many free PDF tools on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

Placing a wider signature
Set Width (pt) to 250 and Position to Bottom center for a full-width signing line, and the signature is scaled up proportionally so it doesn't look stretched.
03
Centering a stamp-style signature
Choose Center as the Position on page 1 to drop the signature in the middle of the page, useful for a stamp-like approval mark.

FAQ
Frequently asked questions
Quick answers to common questions about the Sign PDF.
What does Sign PDF do?
It lets you draw a signature and place it onto any page of a PDF, at the position and width you choose.
Is Sign PDF free to use?
Yes. It's free, with no sign-up, no watermark and no limit on how many files you sign.
Is my file safe when I use this tool?
Yes. Your PDF and signature are handled entirely in your browser using small PDF and drawing libraries loaded from this site — neither is uploaded to a server.
Can I choose exactly where the signature goes?
Yes. Pick from seven preset positions — top or bottom, left, center or right — plus the exact page number and the signature's width.
What if I make a mistake while drawing my signature?
Click Undo to remove just the last stroke, or "Clear signature" to wipe it and start again before signing.
Is this a legally binding electronic signature?
It places an image of your drawn signature onto the page — it doesn't add cryptographic signing or identity verification, so check what your specific use case requires before relying on it for a legally binding signature.
Can I use Sign PDF on my phone?
Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike, including touchscreen signing.
Does Sign PDF have any limitations?
It signs one page at a time with one signature per run; a password-protected PDF needs to be unlocked first with the Unlock PDF tool before it can be signed.
