About Duetto PDF Signature Tool

I was sick of trying to find websites, or free apps to sign PDF's. This extension allows you to upload a PDF, create a signature, place the signature on the PDF and download the 'signed' PDF - doesn't get any easier. No need for Adobe, no need to upload your documents to an unknown server, or buy third party software. I don't collect any personal data, nor track you. YOU ARE WELCOME :>
