Your drawing is read in this browser tab. It is never uploaded to ContractorCounter.

How it works

01
Open your drawing
Drag a PDF into the workspace, or start on the sample sheet already loaded. Nothing uploads — the file is read in your browser.
02
Set the scale
Calibrate against a known dimension once, and every length, area and volume you measure afterwards comes out in real units.
03
Mark up and measure
Clouds, callouts, dimensions, area and count tools — the same set the paid workspace uses, at full capability.

Is it really free?: Yes. The free workspace needs no account and no card. It is the full markup and measurement tool, not a viewer or a watch-only demo. Exports carry a ContractorCounter mark.
Do I have to upload my drawing?: No. Your PDF is opened and rendered inside your browser and is never sent to our servers. Close the tab and nothing of it remains with us.
What do I get by signing up?: Saving. A free session lives in the tab — sign up when you want the work to persist, to come back to it, or to share it with someone else.
Is this a Bluebeam alternative?: For markup, measurement and takeoff on construction PDFs, yes — and it runs in the browser on Mac, Windows and iPad with nothing to install.
