Add a visible signature to a PDF

Use Sign PDF when the document needs a visible signature mark placed on one or more pages. Choose the supported signature method, position the mark, and review the finished copy.

Draw, type, or upload signature artwork

Type, draw, upload a JPG or PNG, or use the optional phone flow to create visible signature artwork.

Place and resize the signature

Move the signature to the intended page position and adjust its size before creating the final copy.

Know what type of signature this is

A visible signature image is not automatically a cryptographic digital signature, certificate-backed identity proof, or legal verification service.

Visual signature questions

Is this a certificate-backed digital signature?

No. The tool places visible signature artwork and does not perform certificate-backed cryptographic signing.

Can I draw, type, or upload a signature?

Yes. Type, draw, upload a JPG or PNG, or use the optional phone flow. Initials and company-stamp marks are also supported.

Can I sign more than one page?

Yes. Place separate marks on multiple pages, with up to 200 placements per job.

Does PDFKaka verify my identity?

No. PDFKaka does not verify the signer's identity.

Will the signature be legally accepted?

Acceptance depends on the recipient, jurisdiction, and process. A visible signature mark is not a blanket guarantee of legal acceptance.

Are my files uploaded?

The PDF remains local in this browser. If you use the optional phone flow, only the signature PNG is sent to the server temporarily for up to 10 minutes; the PDF is never uploaded or sent to the phone.
