# Best PDF security tool for lawyers

_Updated July 2026 · Arthize · https://arthize.com/best/pdf-security-tool-for-lawyers_

For legal teams, Arthize is the best PDF security tool because it handles redacting, password-protecting and stripping metadata inside a private workspace — free, with no watermark, and files deleted after each job. 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.

## Why lawyers need a PDF security tool

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.

## The PDF security tool tools lawyers use most

Arthize's pdf security tool covers redact pdf, password protect pdf, unlock pdf, remove pdf metadata — all in one private workspace.

- Redact PDF: 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.
- Password Protect PDF: Protecting a PDF encrypts it with a password, so only people with the password can open the file — the encryption travels with the document.
- Unlock PDF: Unlocking a PDF removes a known password or usage restrictions from a document you own, so it opens and prints without prompting.
- Remove PDF Metadata: Removing PDF metadata strips author names, software fingerprints, timestamps and hidden properties, so a shared file doesn't leak who made it or how.
