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.

Practical guidance

Add a visible signature to a PDF online

Sign PDF lets you draw, type, upload, or temporarily send signature artwork from a phone, then place and resize visible marks on one or more pages. This is an electronic visual-signature workflow, not a certificate-backed digital signature or identity-verification service.

Draw, type, or upload signature artwork

Choose the method that produces a clear mark, then position it carefully inside the correct signature area.

Draw a signature on a phone for a desktop PDF

The optional pairing flow transfers temporary signature artwork to the desktop session. The PDF itself remains on the desktop browser.

Confirm what type of signature is required

Some documents accept a visible electronic mark, while others require a certificate, verified identity, witness, or regulated signing platform. Check before signing.
