Sign PDF

Sign a PDF Online - Draw, Type, or Upload

Add a handwritten-style signature to any PDF without installing software. Draw with your mouse or finger, type your name in a script font, or upload a PNG/JPG of your signature. Place it on the page, resize it, copy it to every page, and download. Everything runs in your browser — the file is not uploaded to our servers.

How it works

1. Open a PDF from the drop area, or paste with Ctrl+V (⌘V on Mac).
2. Create a signature: Draw on the pad, Type your name, or Upload an image. White backgrounds on photos are removed automatically.
3. Click the page to place it. Drag to move, use the corner handles to resize. Optional: tick Also place today’s date.
4. Use Copy to all pages if every page needs the same signature, then Download signed PDF.

Tips for best results

• On a phone, draw with your finger — it is often cleaner than a mouse.
• A PNG of a signature on white paper works well; this tool knocks out the white so only the ink remains.
• This is a visual signature stamped onto the PDF. It is not a certificate-based electronic signature (DocuSign / Adobe Sign).
• Password-protected PDFs need the password removed first.

Frequently asked questions

Is this a legally binding e-signature?

It places your signature image on the PDF, which many everyday forms accept. It does not create a certified, audited e-sign like DocuSign. For contracts that require that, use a dedicated e-sign service.

Is my PDF uploaded?

No. Signing runs in your browser with PDF.js and pdf-lib. The file stays on your device.

Can I sign more than once?

Yes. Place as many stamps as you need, on any page. Copy one stamp to every page with one click.

Can I sign on my phone?

Yes. Draw with your finger, then tap the page to place the signature.
