Compare PDF for contractors
Updated July 2026
Arthize lets construction and trades teams compare two PDFs in a private workspace — free, with no watermark. Comparing two PDFs highlights what changed between versions — added, removed and edited text — so you can review revisions at a glance.
Why contractors compare two PDFs
A contractor merges a bid, permit and change order into one project file, signs a document from their phone on site, and compresses a photo-heavy progress report to email the client.
Built for bids. Whether it's bids, permits, change orders, Arthize's compare pdf keeps the work inside your private workspace. Bids and client contracts are commercially sensitive; a private workspace keeps them secure.
