PDF files only • Processed entirely in your browser
Restrictions (Optional)
Set what others can do with your PDF even after opening it.
If your PDF only has print/copy/edit restrictions (no open password), leave this blank and click Unlock — it will work automatically.
If this PDF has a real "open password", you must know it to unlock the file — this is true for every PDF tool, not just this one. It's a security safeguard: no browser tool can bypass encryption without the correct password.
Works entirely in your browser. No uploads. No watermarks. No signup.
Sending a sensitive PDF — a salary slip, a contract, a mark sheet — over email or WhatsApp without a password can feel risky. On the flip side, you might receive a PDF that's locked and you know the password but need to remove it before editing or printing. QuickPDFonline's Password Protect / Unlock PDF tool handles both directions in one place.
Add a password so the file can't be opened without it, or use an owner password instead — the file opens freely for anyone, but printing, copying, and editing stay locked until the owner password is entered. Need to go the other way? The Unlock tool removes an existing open or owner password (when you know it) or lifts print/copy/edit restrictions that don't require a password at all. All processing happens directly in your browser — your files are never uploaded to any server.
Useful for students protecting personal documents before sharing, professionals sending contracts that shouldn't be edited, or simply removing an old password you no longer need. No registration, no watermark, no file size restrictions — just fast, private password handling every time.
ध्यान दें (Helpful Tip)
अगर आप किसी PDF को password से protect करना चाहते हैं, तो "Protect" tab चुनें और password डालें — या "Owner password only" option select करें ताकि file bina password khule, sirf print/copy/edit restricted रहे। Unlock करने के लिए मौजूदा password डालें और "Unlock" पर click करें — अगर file में सिर्फ restrictions हैं (open password नहीं), तो password field खाली छोड़ कर भी unlock हो जाएगा। पूरी तरह safe और free।

Enter the current password to unlock, or set a new password and restrictions (print/copy/edit) to protect.

No — your file is never uploaded, transmitted, or stored anywhere. Password protection and removal both happen entirely within your browser. Your password itself never leaves your device either.
An open password is required just to view the PDF. An owner password is different — the file opens for anyone without a password, but actions like printing, copying, or editing stay restricted until someone enters the owner password. Use the "Owner password only" option in the Protect tab if you want your PDF to be freely readable but restricted in what people can do with it.
Enter whichever password you have — the open password if the file asks for one when you view it, or the owner password if you know it. Both can be used to unlock a PDF here. If the PDF opens without asking for a password at all (it only restricts printing/copying/editing), leave the password field blank and click Unlock — it will remove the restrictions automatically.
Yes. The output is a standard PDF file that works on any device — Android, iPhone, Windows, or Mac — and opens in any PDF viewer.
