Universal Converter

Sign a PDF

Make your signature once: type your name and pick a style, draw it with the mouse or a finger, or use a photo of it on paper. Universal Converter finds the signature lines and empty signature fields, or you click on the page where it should go. It saves a signed copy and leaves the original as it was. This is a visible electronic signature, not a certificate-based digital signature.
