PDF Signer & Annotator

Draw your signature once on a transparent canvas pad, then place it anywhere on any page: position and size are percentages of the page, so the same settings land proportionally on A4, Letter or anything else. The stamp is flattened into page content — every viewer renders it identically.

This is a visual signature, not a cryptographic one: no certificate, no trusted timestamp, no PAdES qualification. For everyday forms that's exactly right; for legally qualified e-signatures use a CA-backed service — the tool states this plainly.
