Securely Remove PDF Password Protection
For security reasons, CurePDF can only unlock PDFs when you know the correct password — this tool does not attempt to crack, brute-force, guess, or otherwise bypass a PDF's encryption.
Your password is used once, in memory, to open the file — it is never logged, never stored in our database, and never included in error reports or analytics. Your PDF itself is processed entirely in memory and is never written to disk.
Your Privacy
Your uploaded file, the password you enter, and the unlocked result all exist only for the moment it takes to process your request — nothing is saved afterward. As with any online tool, avoid uploading documents with extremely sensitive information unless you're comfortable with standard web-based processing.
