Digitally Signing a Document

How a PDF is digitally signed depends on how it was created. In most cases, a signature field will have already been added to the document in preparation for your signature. Such documents might also be certified. In some cases, however, you might need to add your own signature field before signing.  Fortunately, Revu makes it simple to do this, too.

If you do not have a Digital ID yet, you will need to create one first. See Creating a New Digital ID.

Documents you have been given to sign might or might not be certified. Some certified documents do not allow any changes to be made to them after certification.

Digitally signed documents cannot be combined with other documents without invalidating the signatures. Combine documents before signing or use Sets to view separate signed PDFs as a single collection. The only option after signing a document that preserves the signature is to create a PDF package.

Documents that have been digitally signed are automatically locked to editing and their security status cannot be changed unless the signatures are cleared. This means that operations that would change the document (for example, adding or deleting pages, flattening markups, running OCR, adding new form fields, and so on) are not permitted; these options are not available/dimmed for these documents.
