About Sign PDF
Sign PDF lets you place a visible signature on a document without printing it. It is useful for approvals, school forms, internal documents, simple agreements, delivery confirmations, and paperwork where a drawn or typed signature is accepted. A visual e-signature is different from a cryptographic digital certificate. It shows intent and is often enough for everyday forms, but some legal, banking, or government workflows may require a certified digital signature from a dedicated signing provider. Before signing, check the signature line, date field, initials boxes, and whether the document needs every page initialed. Save an unsigned copy if you may need to revise the document later.
Updated June 2026: Added practical e-signature guidance for forms, approvals, signature placement, initials, and limits of visual signatures.
