Flatten PDF for contractors
Updated July 2026
Arthize lets construction and trades teams flatten a PDF in a private workspace — free, with no watermark. Flattening a PDF merges form fields, annotations and layers into the page, so nobody can change filled-in values and the file renders everywhere.
Why contractors flatten a PDF
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 flatten pdf keeps the work inside your private workspace. Bids and client contracts are commercially sensitive; a private workspace keeps them secure.
What matters when you flatten a PDF
Flattening bakes form fields and annotations into the page so they can't be changed.
It fixes forms that display differently in different viewers.
A flattened PDF is the safe way to share a completed form.
