No. This tool adds a visual electronic signature (an image of your signature) to the PDF. It is not a cryptographic PKI digital signature and does not provide tamper-proofing or certificate-based identity verification.
PDF electronic signature
PDFAdd an electronic signature to a PDF in your browser: hand-draw with a mouse or touch, type your name in a handwriting style, or upload a signature image. Drag the signature to position it, resize it, and adjust opacity, then export a new signed PDF. Optionally apply the signature to every page. Common uses include signing contracts, internal approvals, receipts, and authorization letters, replacing the print-sign-scan workflow. For legally binding cryptographic signatures, use a dedicated PKI tool. All processing is local — nothing is uploaded.
