E-Signature

Add a signature to your PDF

What is E-Signature?

Adding a digital signature to a PDF formalizes agreements without printing. PDFStream's signature tool lets you draw your signature on a canvas, then places it on the PDF page at your chosen position. Draw your signature with a mouse or touch input. Scale and position it on the page. Download the signed PDF — the signature is embedded as an image annotation, visible in all PDF readers. Use cases: signing rental agreements or service contracts without printing, adding an approval signature to an internal document, signing a letter or certificate, or annotating a PDF with a personal sign-off before sending.

Practical tips

Visual, not certificate-based

The signature is placed as an image, which suits everyday agreements but isn't a certificate-based digital signature.

Sign several places at once

Place the signature on multiple pages, such as initials on each page and a full signature at the end.

Draw on a touch screen

Using a phone or tablet with a finger or stylus produces a more natural signature than a mouse.
