Forms & Signatures — Free Unlimited

Add a visible signature to PDF documents or flatten completed form fields into fixed page content. Review the saved result before sharing; a drawn signature is not a certificate-based digital signature.

Sign PDF

Draw a signature and add it to PDF documents without printing. This tool adds a visual signature, not a certificate-backed digital signature.

Flatten PDF

Flatten interactive form fields into fixed PDF content. Convert editable forms to static documents and prevent changes through form controls.
