A signing tool for people who just need it signed

Sign PDF started from a simple irritation. Getting a lease or a quote signed online meant opening a blank PDF in an expensive tool and dragging twenty boxes onto it by hand, then paying for a year up front. So we built the version we wanted: upload the document, and the signature, initials and date boxes are already where they belong, assigned to the right person.

The people who sign never make an account. They confirm a code sent to their email, sign on whatever they have to hand, and everyone gets back the same sealed PDF with a certificate of completion: who signed, when, from which IP address and device, and a fingerprint of the file. Anyone can check a copy on our verify page.

It costs $5 a month for 2 documents or $10 a month for as many as you like, paid monthly. There is no annual contract to escape from.
