Sign a PDF

You can sign a PDF to indicate your approval. A PDF can be signed more than once and by more than one person. When you sign a document, your digital signature appears in the signature field. The appearance of the signature depends on options you choose. The actual information for your digital signature is embedded in the PDF.
