💡 Leave blank and click Unlock — the tool will automatically remove owner restrictions (print/edit/copy locks) without needing a password.
Only enter a password if the PDF asks for one to open it (user password).
⚠️ If the PDF requires a password just to open it, you must enter that password. This tool cannot crack or guess unknown passwords — AES encryption cannot be bypassed.

Need to unlock a PDF and remove its password? CleanPDF's free PDF unlocker tool lets you remove PDF password protection directly in your browser — no upload, no sign-up, no software to install. Whether your PDF has an owner password (restricting print, copy, or edit) or a user password (blocking access entirely), our tool handles both. Simply upload your file, enter the password if required, and download a fully unlocked PDF in seconds.
How to Remove Password from PDF — Step by Step
Upload your password-protected PDF — drag & drop or click to select. Your file never leaves your device.

Click "Unlock PDF Now" — our tool automatically detects the encryption type and strips it in your browser.
Download the unlocked PDF — get a clean, restriction-free PDF file ready to open, edit, and share freely.
Types of PDF Passwords — What Can Be Removed Without a Password?
Understanding which type of PDF protection you're dealing with is key:
✅ Owner Password (Restrictions)
Blocks printing, copying, or editing. The PDF opens freely for anyone. Can be removed without entering any password — just upload and click Unlock.
🔑 User Password (Open Password)
Blocks the PDF from opening at all. Requires the correct password to unlock. AES-128/256 encryption cannot be bypassed — you must know the password.
Why Remove Password Protection from a PDF?
There are many legitimate reasons to unlock a PDF you own or have permission to access:
Editing: PDF editors like Adobe Acrobat and Foxit require an unlocked file before allowing changes.
Printing: Owner-locked PDFs often block printing — unlock to print freely.
Copying text: Extract text or images from documents you have rights to use.
Merging PDFs: Most PDF merge tools require unlocked files to combine pages.
Archiving: Store long-term documents without depending on a password being remembered.
Sharing: Distribute to colleagues or clients without password coordination overhead.
🔒 Zero-knowledge privacy: We never see your PDF, your password, or any metadata. All decryption runs inside your browser using WebAssembly. No server, no logs, no tracking.
Is It Legal to Remove a PDF Password?
Removing password protection from a PDF you own or have explicit permission to modify is completely legal. Common legitimate use cases include unlocking your own documents, removing restrictions from files your organisation produced, and accessing archived files whose passwords were forgotten. You should never use this tool to access documents you do not have authorisation to view or modify.
Frequently Asked Questions About Unlocking PDFs
Can I unlock a PDF without knowing the password?
Yes — but only for owner-password (restrictions-only) PDFs. These files open freely without a password; the restriction only prevents printing, copying, or editing. Our tool removes those restrictions automatically. For user-password PDFs (which require a password just to open), the AES encryption cannot be bypassed — you must have the correct password.
Is it safe to unlock a PDF online?
With CleanPDF, yes — completely safe. Your PDF and password are processed entirely inside your browser using client-side JavaScript. No data is ever uploaded to our servers. We have no access to your file or credentials at any point.
What PDF encryption types does this tool support?
Our tool supports 40-bit RC4 (PDF 1.1–1.3), 128-bit RC4 (PDF 1.4–1.5), 128-bit AES (PDF 1.6+), and 256-bit AES (PDF 2.0) — covering virtually all password-protected PDFs created by Adobe Acrobat, Microsoft Word, LibreOffice, and other tools.
Will unlocking change the PDF content or quality?
No. Unlocking only removes the encryption layer. All text, images, fonts, vector graphics, page layout, and embedded metadata remain 100% identical to the original. The file size may decrease slightly since encryption overhead is removed.
What is the maximum PDF file size supported?
There is no server-side file size limit since all processing happens in your browser. In practice, the limit is determined by your device's available RAM — most modern computers can handle PDFs up to 500MB or larger without issues.
Can I re-add a different password after unlocking?
Absolutely. After downloading your unlocked PDF, use our Protect PDF tool to add a new password with AES-128 encryption. You can set both a user password (to open) and an owner password (to control permissions).
Does this work on iPhone, iPad, and Android?
Yes. CleanPDF's unlock tool is fully responsive and works on all modern browsers including Chrome, Safari, Firefox, and Edge — on desktop, tablet, and mobile devices. No app installation required.

Unlock PDF vs. Other Tools — Why CleanPDF?
Most online PDF unlockers upload your file to a remote server, process it there, and return the result. This means your confidential documents — contracts, invoices, medical records — pass through a third party's infrastructure. CleanPDF is different: everything runs inside your browser. The PDF bytes never leave your machine. This makes CleanPDF the safest choice for sensitive documents.
