Security PDF tools
Only production-ready tools are listed here.
Choose PDF protection, unlocking or redaction
Protect a PDF with a password
Add an opening password when password-based access control suits the document. Store that password safely and use an appropriate way to share it with the recipient.
Unlock a PDF you can access
Remove password protection only when you know the correct password and have permission to create an unprotected copy. PdfnMore does not recover or bypass a forgotten password.
Redact selected PDF content
Mark areas for redaction and download a rebuilt, flattened PDF. This changes selectable text and interactive features; inspect every output page rather than assuming a visible black box is enough.
Frequently asked questions about security PDF tools
Can PdfnMore bypass a PDF password I do not know?
No. Unlock PDF requires the correct password and is intended only for documents you are authorized to access.
Does Protect PDF replace secure file-sharing practices?
No. PDF passwords can be useful, but sensitive workflows may also need secure delivery, access controls and careful password handling.
Is PDF redaction available here?
Yes. Redact PDF removes manually selected areas by rebuilding flattened page images. Review every output page and keep the original separate.
