Sign PDF
e-Sign a PDF — draw or type your signature and place it on the page.
Add your signature to a PDF without printing or scanning. Draw your signature with a mouse or finger, or type your name in a handwriting style, then drag it exactly where it belongs on a live page preview and resize it to fit. Sign a single page or stamp every page at once, then download the signed PDF. Everything — page rendering and signing — runs 100% in your browser (pdf.js + pdf-lib); your document never leaves your device. No sign-up, no watermark.

How to use Sign PDF
Upload your PDF
Drop the document you need to sign into this free online sign PDF tool or click to select it — it loads in your browser and is never uploaded to a server.
Create your signature
Draw your signature with a mouse or finger on the pad, or switch to Type and enter your name in a handwriting-style font — whichever looks right for you.
Place it on the page
Drag the signature to the exact spot it belongs and use the size slider to make it fit, watching it update live on the real page preview as you go.
Sign one page or all
For multi-page documents you can tick “place on all pages” to stamp the same signature in the same position on every page in one step.
Download the signed PDF
Click Sign & download PDF and your signature is baked into the document with pdf-lib, producing a signed file you can send straight back.
Frequently asked questions
How do I sign a PDF online for free?
Upload your PDF, draw or type your signature, drag it into place and click Sign & download PDF. It's free, has no watermark and runs entirely in your browser.
Can I sign with my finger on a phone?
Yes. The signature pad supports touch, so you can draw a natural signature with your finger on a phone or tablet, then position and download the signed PDF.
Is my document uploaded anywhere?
No. The page preview (pdf.js) and the signing (pdf-lib) both run locally in your browser. Your PDF and signature never leave your device.
Can I place my signature on every page?
Yes. For multi-page PDFs, tick “place on all pages” and your signature is stamped at the same position on every page at once.
Is a drawn signature legally valid?
In many countries a simple electronic signature is acceptable for everyday agreements, but requirements vary. For high-stakes or regulated documents, check the rules that apply to you.
Does the signature become part of the PDF?
Yes. The signature image is embedded into the page content, so it displays and prints in every PDF viewer — not as a separate removable layer.
Can I type my signature instead of drawing it?
Yes. Switch to the type option and enter your name in a handwriting-style font, then drag it onto the page and resize it — handy if you're on a desktop without a touchscreen or prefer a neat, consistent signature.
Do I need to print and scan to sign a PDF?
No — that's the whole point. Draw or type your signature, place it on the page and download the signed PDF entirely on your device, so there's no printing, scanning or uploading involved.
