Secure PDF
Unlock PDF files
Unlock PDF files by removing encryption with the current password.
Choose a file
Choose one protected PDF up to 120 MB and enter its password.
Save a PDF without its password
Use the current password to decrypt a PDF and create an unprotected copy. The protected source remains unchanged.
Enter a password you already know
This tool does not recover, guess or bypass a missing password. An incorrect password stops the operation without producing a file. Use it only for a PDF you are authorised to save without protection.
Use the open copy where it is needed
Removing encryption can let you merge a statement with other PDFs or use a printer, preview tool or document system that cannot open protected files.
The new file no longer asks for a password. Save it in a private or approved location if its contents are sensitive, and consider whether an unprotected copy is necessary at all.
Check the unprotected result
Decryption and output checks run in this browser; the password is not sent to Rebuildfree. Open the downloaded PDF without entering a password and check the pages, forms and links you need.
To change an existing password, unlock the PDF, then use Protect PDF on the open copy. Check the new protected file before removing any intermediate unprotected copy.
Questions
What is required to unlock a PDF?
Enter the current password. Only unlock files you are authorised to change; the tool cannot guess or bypass a missing password.
Can a missing password be bypassed?
No. An incorrect or missing password ends the operation without producing an unlocked file.
Where is the password used?
The password is used inside this browser tab and is not sent to Rebuildfree or stored for later use.
Why is an owner password required?
Some PDFs allow viewing with one password but require the owner password to remove restrictions.
