How It Works
Why Sign a PDF Online
Printing a document just to sign and re-scan it is slower than doing it directly in the file. This tool lets you draw a signature with your mouse or finger, or type your name in a signature-style font, then drag it exactly where it needs to go on any page — contracts, forms, letters, or agreements — without installing anything.

What Does "Sign PDF Online" Do?
This tool turns a signature you draw or type into a small transparent image, then lets you drag it into exactly the right spot on any page of your PDF before permanently embedding it into the file using pdf-lib. The result is a normal PDF with your signature baked into the page content — no special reader or plugin needed to view it afterward.
It's a visual signature, not a cryptographically certified digital signature with a verifiable audit trail — the right tool for everyday paperwork, but check specific legal requirements for documents that mandate a certified e-signature service.
Draw vs Type — Which to Use
| Method | Best for |
|---|---|
| Draw | Matching your actual handwritten signature, especially on a touchscreen |
| Type | A quick, consistent, legible signature when handwriting isn't practical |
Frequently Asked Questions
Is my PDF uploaded to a server?
No. The PDF is rendered, signed, and re-saved entirely inside your browser using pdf-lib and pdf.js — the file and your signature are never transmitted anywhere.
Is this a legally binding electronic signature?
This tool visually places a signature image onto the page — it doesn't add cryptographic signing, a certificate, or an audit trail the way dedicated e-signature services do. For most everyday documents a visual signature is accepted, but check the specific legal requirements for anything that needs a certified digital signature (like some contracts or government forms).
Can I draw my signature, or do I have to type it?
Both — draw it with your mouse, finger, or stylus on the signature pad, or type your name and have it rendered in a signature-style font. Use whichever looks more like your real signature.
Can I sign more than one page, or place my signature more than once?
Yes — place your signature on as many pages and positions as you need before downloading. Each placement is added to the same document.
Can I resize or reposition the signature before placing it?
Yes — drag the signature box anywhere on the page preview and use the size slider to scale it, then click "Place Signature on This Page" once it's positioned correctly.
Can I sign a PDF on my phone?
Yes — drawing a signature with your finger on a touchscreen often looks more natural than with a mouse. The page works the same on iOS and Android browsers.
Does it work on any PDF?
Any standard, unencrypted PDF. Password-protected files need their protection removed first in your PDF viewer.
