PDF Security Tools

PDF security covers three separate jobs that people often lump together: locking a file so only you can open it, removing a lock that is in your way, and permanently removing text you no longer want visible.
Redaction is the one to be careful with. Covering text with a black box hides it on screen but leaves the characters underneath, recoverable by anyone who copies the page. Real redaction removes them from the file.

Password protection here controls who can open the file and what they may do with it. It is not encryption for data in transit, and it is not a replacement for a properly managed document-sharing system.
PDF Security questions
- Can I remove a password from a PDF I have the right to open?
- Yes, if you know the current password. Unlock PDF removes a known password and any owner restrictions. It cannot recover the contents of a file whose password you do not have — that is the entire point of the password.
- Is redacting a PDF here permanent?
- Yes, the text is removed from the file rather than covered. Always check the result by selecting the redacted area and trying to copy it, and keep an unredacted copy somewhere safe until you have confirmed the redacted version is correct.
- How secure is password protection on a PDF?
- It is enough to stop casual sharing and to make the file open-only. It is not a substitute for encrypting a highly sensitive document with dedicated software, and a password cannot protect a file from someone who already has it open.
- Are password-protected PDFs handled by the tool?
- All of these run in your browser, so a protected document is never uploaded anywhere. That matters more for this category than for any other, which is why the tools are built to work locally.
