About

Built by a working site manager.

PDF Picasso began as the mark-up tool in a set of programs for running building sites. It was written for the drawings that land in a site manager’s inbox every day: clouding a change, checking a dimension, stamping a drawing approved, putting the latest revisions together for the gang, signing a form on the bonnet of the van.

It’s free in your browser because a PDF editor shouldn’t need an account or an upload. A desktop app for a one-off £4.99 is on its way.

PDF Picasso is run by Sitehelm Limited, a company registered in England and Wales.
