PDF stamps are a great tool for protecting documents. Using a stamp is a simple way to add a status to a document. They can be used to create custom PDF statuses that include a logo, company name, contact information, or even a unique identifier.

1-1: What is Dynamic Stamp in PDF?

Dynamic stamps enable you to add a personalized touch to business documents such as contracts or invoices. They also allow you to include additional information, such as signatures, names, dates, or logos. These stamps are created by adding form fields such as text boxes to an existing PDF Stamp. Adding these fields during the creation of the stamp flattens them out, which means the fields are no longer part of the stamp file. This makes it impossible to edit them later.
