## What does this tool do?

Puts your signature on the pages you choose. You draw it there with the mouse or your finger, or you
upload a photo of the signature you use on paper, pick where it goes and how big it is, and get a new
PDF.

## What this is, and what it is not

This **pastes an image onto the page**. It is what you need for most paperwork: a form, a delivery
note, a lease your landlord wants back by email.

It is **not** a cryptographic signature. Nothing here proves the document has not been changed after
you signed it, and nobody can verify who signed it from the file alone. That needs a certificate and
your private key — a different kind of tool, and one that has no business running in a web page that
promises your documents stay on your computer.

## How it is placed

The grid is the page: pick a corner, an edge or the middle. The size is in millimetres, so a 50 mm
signature is the same on an A4 sheet and on a small one, and the distance from the edge is yours too.
The signature keeps its proportions: it is never stretched to fit.

## Keep in mind

Nothing is uploaded. The PDF is read and written in your browser, and the original file is not
touched — if the signature lands somewhere odd, try again on the same file.
