Best PDF security tool for startups
Updated July 2026
For startup founders and 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. Fundraising materials and cap tables are highly confidential; private processing is critical.
Why startups need a PDF security tool
A founder exports the pitch deck to PDF, merges it with financials into a data-room file, and sends a SAFE for e-signature — without paying for enterprise document software.
The PDF security tool tools startups 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.
