How it works
What is the digital signature on a PDF?
A digital signature on a PDF is an electronic form of a signature that provides a secure and verifiable way to sign documents. It uses cryptographic techniques to ensure the integrity and authenticity of the signed document. Unlike a traditional handwritten signature, a digital signature creates a unique digital fingerprint that is linked to the signer, making it difficult to forge. This method is widely accepted in the United States for various legal and business documents, providing a reliable way to confirm the identity of the signer and the integrity of the document.
How to use the digital signature on a PDF
Using a digital signature on a PDF involves a few straightforward steps. First, open the PDF document you wish to sign using airSlate SignNow. Next, select the option to add a signature. You can create a new digital signature by drawing it, typing your name, or uploading an image of your handwritten signature. Once your signature is ready, place it in the appropriate location on the document. After positioning your signature, you can finalize the signing process by saving the document. This ensures that your signature is securely embedded within the PDF, maintaining the document's integrity.

This legal standing makes digital signatures a secure and efficient option for signing contracts, agreements, and other important documents.
