How Digital Signatures Work

Digital signatures provide a way to authenticate electronic documents. Our tool creates a visual representation of your signature (handwritten, typed, or uploaded image) and embeds it as an image layer onto your PDF. While this is a visual signature rather than a cryptographic digital certificate, it is legally acceptable for most business and personal use cases, including contracts, agreements, and forms.

Frequently Asked Questions

Is a digital signature legally binding?

Yes! Electronic signatures are legally recognized in most countries under laws like the ESIGN Act (US) and eIDAS (EU). Our tool creates a visual representation of your signature that carries the same legal weight as a handwritten signature on paper documents.

Is my signed document secure?

Absolutely! All processing happens locally in your browser. Your PDF and signature never leave your computer. No servers, no cloud storage, no third-party access.

Can I save my signature for future use?

Currently, you need to create your signature each session. For security reasons, signatures are not stored. You can, however, upload a signature image file for repeated use.

Can I sign multiple pages?

Yes! Use the Prev/Next buttons to navigate through pages. You can place signatures on as many pages as you need before saving.
