# Redact PDF for contractors

_Updated July 2026 · Arthize · https://arthize.com/for/contractors/redact-pdf_

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.
