Sign PDF

Sign a contract, consent form or delivery note without printing and scanning it. Type your name in a handwriting style, or photograph your real signature on white paper — the tool removes the paper background and places the ink on the page you choose, optionally with the date. The PDF is signed inside your browser and never uploaded.

How to use this tool

1. Choose the PDF to sign.
2. Either type your name and pick a handwriting style and ink colour, or upload a photo or scan of your signature.
3. Choose the page — usually the last — and the position: bottom right, left, centre or exact X and Y in millimetres from the top-left corner.
4. Set the width, tick “Write a date” if the form needs one, then download the signed PDF.

Formula

Signature height = width × (picture height ÷ picture width). Positions in mm are converted to PDF points with 1 mm = 72 ÷ 25.4 ≈ 2.835 pt.

Preset positions keep a 15 mm margin from the page edges. On pages that are displayed rotated, the position is measured as you see the page, so the signature always appears upright.

Example

On an A4 page (210 × 297 mm), a 50 mm wide typed signature whose picture is 4 times wider than tall comes out 12.5 mm tall. Placed bottom right, its left edge sits at 210 − 15 − 50 = 145 mm from the left and its bottom edge 15 mm above the page edge.

Visual signature, not a digital certificate

This adds an image of a signature, which is what most everyday forms need and what many online signing services call a simple electronic signature. It is not a certificate-based digital signature that proves who signed and detects later changes. Some contracts, government filings or notarised documents require that, or a handwritten signature — check what the recipient accepts.
