Show HN: A simple web app for scaled PDF measurements

Hi All!

I threw together this simple client side only tool (HTML/JS/CSS) to scratch my own itch on a home project. I needed to do some basic measurements of a platt of survey and could not find a simple/free tool to do this. So I made my own.

It's very basic and buggy, but works well enough for simple tasks. Will continue to slowly improve - especially if others find it useful.
