Redact PDF for lawyers
Updated July 2026
Arthize lets legal 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 lawyers redact a PDF
Before a filing, a paralegal merges statements and exhibits into one bundle, adds consistent page numbers for the court, and redacts personal data so nothing privileged leaks — all inside a private workspace rather than a free public converter.
Built for contracts. Whether it's contracts, court bundles, exhibits, Arthize's redact pdf keeps the work inside your private workspace. Client files are privileged. A contract or discovery packet uploaded to a stranger's ad-funded server is a confidentiality risk lawyers can't take.
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.
