Why Use a Free Online PDF Signature Tool?
Signing PDFs digitally has become essential in modern workflows — from employment contracts and lease agreements to tax forms, NDAs, invoices, permission slips, and remote business transactions. Traditional methods (printing, signing by hand, scanning) are slow, wasteful, and inconvenient. Digital signatures save time, reduce paper use, and provide a legally accepted way to indicate agreement or approval.
Many online signature services require account creation and upload your documents to their servers — raising serious privacy and data security concerns, especially for sensitive or confidential files. This free PDF Sign Tool solves that problem: it runs 100% in your browser using PDF-Lib. Your document and signature never leave your device.

Frequently Asked Questions
Is this PDF signature tool legally binding?
It creates a visible electronic signature (e-signature) that is widely accepted for most everyday documents. For documents requiring certified digital signatures with cryptographic certificates (e.g. advanced/qualified e-signatures), use specialized services compliant with eIDAS, ESIGN Act, etc.
Is my document and signature private?
Yes — completely. Everything happens locally in your browser. No file or signature data is sent to any server.
Can I sign multiple pages or only the last one?
You can apply the signature to every page (bottom positions) or only the last page — ideal for most contracts where signature appears at the end.
How do I create a good-looking signature?
Use a stylus/pen on touchscreen devices for natural handwriting, or draw slowly with mouse. You can also type your name in a stylized font as fallback.
Does it work on mobile phones and tablets?
Yes — fully touch-compatible. Draw your signature directly with finger or stylus on mobile devices.
What if my PDF is password protected?
Protected PDFs cannot be signed without the password. Remove protection first using appropriate tools if you have access.
Can I add multiple signatures or fields?
Current version adds one signature block per document. For complex forms with many fields, dedicated e-signature platforms may be better suited.
