Protect / Remove PDF Password
âšī¸ How it works:
- Upload your PDF file
- Choose Protect (add a password) or Remove Password
- Enter the password and download the result
Password-Protect or Remove a Password from a PDF for Free
Keep a PDF private by adding a password, or remove the password from a PDF you're able to open. Protect encrypts the file with strong AES-256 so it can't be opened without the password; Remove Password takes a password-protected PDF (and its correct password) and gives you back an unrestricted copy. Everything is processed privately on our server — no third-party service. No sign-up and no watermarks.
How to Password Protect a PDF
- Click the upload area above or drag and drop your PDF (up to 10 MB).
- Pick Protect to add a password, or Remove Password to take one off.
- Enter the password and download your new PDF.
Key Features
- AES-256 encryption – the strongest of the standard PDF methods, and the one modern readers expect
- Fully locked, not just restricted – the file cannot be opened at all without the password
- Remove passwords too – take the password off a PDF you can already open
- It tells you if you picked the wrong mode – upload a locked file and choose Protect, and it will say so rather than failing quietly
- Private – files and passwords are processed on our server and not stored
Locked, Not Just Restricted
PDFs can carry two different kinds of password, and the difference matters.
- An owner password only sets restrictions — no printing, no copying — while still letting anyone open the file. These restrictions are widely ignored by PDF software and are trivial to strip out, so they protect very little.
- A user password encrypts the document itself. Without it the file cannot be opened at all, by any reader.
Protecting a PDF here sets both to the password you choose, so the document is genuinely encrypted rather than politely discouraging people. Combined with AES-256, that is real protection — which also means there is no way back in if you forget the password.
When You Might Need This
- Emailing a contract, payslip or bank statement that should not be readable if it goes astray
- Sending personal documents — an ID scan, a medical letter — where the inbox is not the only risk
- Sharing a file through a service you do not entirely trust
- Meeting a requirement to send sensitive documents encrypted
- Taking the password off a statement your bank sends locked every month
- Removing a password before uploading a file to a system that cannot open protected PDFs
- Unlocking a document so you can merge, split or otherwise edit it
- Clearing a password you set long ago and no longer need
Frequently Asked Questions
Upload the file, choose Protect, type the password you want and download the result. Anyone opening that PDF afterwards — in any reader, on any device — will be asked for it. Send the password separately from the file itself: emailing both together defeats the point, since whoever intercepts one has the other.
Upload the protected file, choose Remove Password, and enter the password it currently uses. You get back an ordinary PDF that opens without one. The tool checks the password is right before it does anything — if it is wrong you are told so, and nothing is produced.
The file cannot be opened, by us or by anyone else. AES-256 has no back door and no master key, which is precisely what makes it worth using. There is no recovery, no reset and no support request that will help — so if the document matters, write the password down somewhere safe before you send the file anywhere, or keep an unprotected copy.
No. To remove a password you must know and enter the PDF's correct password — the tool then strips the protection for you, but it does not crack or bypass unknown passwords.
Protected PDFs use AES-256 encryption, the current standard supported by modern PDF readers. Anyone opening the file will need the password you set.
Yes. Your PDF is processed on our own server and not stored long-term, and the password is only used to process your file — it isn't saved or shared.
