What is digital PDF signing?

Digital PDF signing is the process of adding a secure, verifiable signature to a PDF document. Unlike a simple scanned signature, a true digital signature can include cryptographic validation, but for everyday use, adding an image or drawn signature creates a legally accepted electronic signature. A modern sign pdf online tool lets you place your signature anywhere on the page, resize it, and save the signed PDF – all without printing or scanning.
