PDF tool
Sign PDF
Add a visual signature stamp to a PDF. NOT a PKI signature — anyone with image editing can remove it. For legal non-repudiation, use Adobe Acrobat or DocuSign.
This is a visual signature, not a certificate-based PKI signature. The output X-Signature-Kind header reports 'visual-no-pki'. For legal binding signatures, use Adobe Acrobat, DocuSign, or another PKI service.
