How to Put Signature on PDF Document?

A PDF (Portable Document Format) file is a versatile and portable file format that can be viewed and printed on various devices. It is often used for sharing documents that need to maintain their original formatting and layout. One of the essential features of a PDF document is the ability to add a digital signature. A digital signature allows the signer to authenticate the document and ensure its integrity.

Why Sign a PDF Document?

There are several reasons why you might need to sign a PDF document:

• To authenticate the document: A digital signature can verify the signer’s identity and ensure that the document has not been tampered with. This is essential for documents that need to be legally binding, such as contracts, agreements, and financial statements.
• To ensure document integrity: A digital signature can detect any changes made to the document after it was signed. This helps prevent fraud and ensures that the document remains valid even if it is shared or copied.
• To comply with regulations: Many industries and organizations have regulations that require documents to be signed electronically. For example, the U.S. Food and Drug Administration (FDA) requires electronic signatures for certain types of documents related to drug development and manufacturing.
