Why this exists

A small tool, built
on purpose.

There are other ways to sign a PDF. Here's what we were actually trying to fix.

The problem

Signing a PDF usually means one of three things: printing it, signing it, and scanning it back in; drawing a shaky signature with a mouse or a fingertip; or handing your document to a big platform built for teams and contracts, when all you needed was to put your name on one page.

None of those felt right for something as simple as "I need my actual signature on this document, right now, without any of that." So we built the version of this tool we actually wanted to use ourselves.

What we focused on

Two things, done well, rather than a long list of features done half-heartedly:

  • A real signature, not an approximation. Photograph your actual signature on paper and StampMyPDF automatically lifts it off the background — no design skills, no manual erasing.
  • Nothing leaves your device. The document you're signing might be a lease, a contract, or something else you'd rather not hand to a server you don't know anything about. So we don't ask you to.

We won't pretend this is the only tool that does this — it isn't. What we can say is that we built it carefully, kept it honest about its limits (see the FAQ), and use it ourselves.
