About this tool

PDF annotation lets you add notes, drawings, highlights, typed text, and signatures directly onto the pages of a PDF document. This is commonly used for reviewing contracts, filling out forms, providing feedback on documents, or signing agreements without printing them. A digital signature added directly to a PDF is convenient, portable, and accepted in many professional contexts as a valid sign-off.
