About Signing PDFs

Signing PDFs electronically allows you to securely sign documents with a legal and verifiable digital signature, ensuring authenticity and integrity.

What is PDF Signing?

PDF signing refers to the process of adding a digital signature to a PDF document, confirming its authenticity and ensuring that the document has not been altered since it was signed.

Security Features

When signing a PDF, cryptographic methods ensure the document is protected. The digital signature guarantees that the signer is verified, the document hasn't been tampered with, and the signer cannot deny signing the document.

Legal Validity

Signed PDFs are legally binding in many countries, especially when the digital signature complies with local regulations and industry standards for secure document signing.

Common Use Cases

PDF signing is commonly used for contracts, agreements, tax forms, legal documents, and financial statements, ensuring the integrity and authenticity of these important files.

How PDF Signing Works

The document is hashed (a unique digital fingerprint is created). The hash is then encrypted using the signer's private key, forming the digital signature. This can be verified by anyone using the signer's public key.

Benefits of PDF Signing

PDF signing enhances security, reduces paperwork, speeds up document processing, and ensures authenticity and legal compliance, all while saving time and reducing environmental impact.
