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.
