What PDF Signer does

PDF Signature Mark Tool is a free online PDF signing utility that operates entirely within your web browser. Upload any PDF file and add a signature by drawing it freehand or typing text, then position it anywhere on the document pages. The output is a local visual-signature copy suitable for routine use, not an identity-verified e-signature or audit trail. The tool processes files in the current browser session without requiring account creation or software installation, keeping selected files private to your tab. After signing, you can download the modified PDF and inspect it before sharing, while retaining the original file for comparison. This makes it ideal for quick annotations, form fill-ins, or personal document marking where formal verification is unnecessary.
