Adding a signature to a PDF is the process of inserting an electronic or handwritten signature into a PDF document. This is commonly done to authenticate a document or to indicate approval or consent. For example, a business contract may require the signatures of both parties to be legally binding.
The ability to add a signature to a PDF is a valuable tool in many industries and has become increasingly important with the rise of electronic signatures. It offers convenience, security, and legal validity, making it an essential feature for anyone who works with PDFs.
