Sign PDF
Add a visible signature to a PDF — drawn, typed, or an uploaded image. Processing happens in this browser — your file and signature are not uploaded to JCF Labs, and nothing is saved to this browser's storage between visits.
This tool adds a visible signature to the PDF. It does not create a certificate-based cryptographic digital signature, and JCF Labs does not verify the signer's identity through this free tool. It has no legal-enforceability guarantee — check your own jurisdiction's and counterparty's requirements before relying on it.
