Redact PDF for contractors
Updated July 2026
Arthize lets construction and trades teams redact a PDF in a private workspace — free, with no watermark. Redacting a PDF permanently removes the underlying text and images under a black box — not just covering them — so hidden data can't be recovered.
Why contractors redact 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 redact 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 redact a PDF
Real redaction deletes the underlying content; a black rectangle alone can be removed to reveal the text.
Copying text from under a fake redaction box exposes the hidden data — a common leak.
Redaction should also clear document metadata that can leak names and edit history.
