Common questions
Short answers for contractors
Can I count items on a PDF construction drawing?
Yes. ContractorCounter lets users place count marks on PDF drawings and keep those counts visible alongside the rest of the markup context.
Is ContractorCounter only for estimating?
ContractorCounter is focused on drawing markup, PDF annotation, calibrated measurement, counts, stamps, comments, and clean exports. Estimating can happen after the markup work is clear.
Does it work in the browser?
Yes — ContractorCounter is fully browser-based, which means it runs on Windows, macOS, and iPad without an installer, a Windows-only desktop dependency, or a virtual-machine workaround for Mac users. Upload PDF or image drawings, calibrate the scale once per sheet, and the full markup, measurement, and counting workflow runs in the tab — at the desk or on site. Because the workspace lives in the browser, the same drawing opens identically on every machine, so the office and the field are always looking at the same markups without anyone syncing files or matching software versions. If your team has been locked out of desktop-first tools on Mac or iPad, this is the structural difference to test first.
