Sign PDF

Frequently Asked Questions

Is this PDF signing tool free?

Yes, 100% free. No account, no subscription, no file size limits (up to 50 MB).

Are my files safe? Are they uploaded anywhere?

All processing runs entirely in your browser using JavaScript. Your PDF and signature never leave your device — nothing is uploaded to any server.

What types of signatures can I add?

You can draw a freehand signature with your mouse or finger, type your name in Helvetica, Times New Roman, or Courier fonts, or upload a PNG/JPG image of your existing signature.

Can I place the signature on a specific page?

Yes. Use the page selector arrows to navigate to any page in your PDF, then click to place your signature. You can also drag it to reposition and resize it using the corner handle.

Is this legally binding / cryptographic signing?

This tool adds a visual signature image to the PDF — similar to signing with a pen. It does not add a cryptographic digital certificate. For legally binding e-signatures with audit trails, use a dedicated e-signature service.

Does it work on mobile?

Yes, touch drawing works on iOS and Android. You can draw your signature with your finger on the touch canvas.
