If you have a password-protected PDF and you know the password, you can remove the password from the PDF permanently — so you don't have to enter it every time, or so you can share an open copy with colleagues. This guide shows you how to do it for free online. Only unlock PDFs that you own or have permission to unlock.
When Would You Remove a PDF Password?
You'd want to unlock a PDF if:
- You received a password-protected PDF from a vendor or client and you no longer need the restriction — you're the authorised party and want a friction-free copy.
- You set a password yourself but the document is now ready to be shared openly.
- You need to process the PDF with another tool (merge it, compress it, add page numbers) that requires an unprotected file.
- Your team regularly receives protected PDFs and constantly entering passwords is slowing down your workflow.
Important note: This tool only works on PDFs where you know and can enter the correct password. It cannot crack or brute-force a password. If you don't know the password, you cannot unlock the PDF with this tool.
How to Remove a PDF Password — Step by Step
The Unlock PDF tool processes the file on our server. Your PDF and password are sent over an encrypted (HTTPS) connection, the password is removed there, and the file is deleted as soon as the unlocked copy has been returned to you. Files can be up to 50 MB.
Step 1 — Upload the password-protected PDF
Go to want2convert.com/unlock-pdf and drag your protected PDF into the upload zone.
Step 2 — Enter the current password
Type the password that currently protects the file. This is required for PDFs that need a password to open — the tool cannot bypass security, it simply uses your provided password to open the file and then saves it without encryption. (If the PDF opens without a password and only has editing or printing restrictions, leave the password field blank.)
Step 3 — Click "Unlock PDF" and download
Click Unlock PDF. The tool opens the PDF with your password, saves it without password protection, and prepares it for download. Click Download to save the unlocked copy.
The original file on your device is unchanged — you now have two copies: the locked original and the new unlocked version.
Can You Unlock a PDF Without the Password?
No — not using this tool, and you should not try to remove protection from someone else's document without permission.
PDF open passwords use AES encryption (AES-128 or AES-256 depending on when the PDF was created). A strong password cannot be brute-forced in any reasonable timeframe.
There are third-party "PDF password recovery" tools that attempt brute-force or dictionary attacks on weakly protected PDFs. These:
- Only work if the password is short or common
- May be unlawful or a breach of terms when used on PDFs you are not authorised to open
- Are not what this tool does
If you genuinely don't know the password to a PDF you own, the only recourse is to contact whoever created and password-protected the document.
Difference Between Open Password and Permissions Password
PDFs support two types of protection:
Open password: Prevents opening the file at all. Anyone who tries to open the PDF is prompted for the password. This is what most people mean by "password-protected PDF."
Permissions password (owner password): The file opens without a password, but certain actions — printing, copying text, editing — are restricted. Only the owner password unlocks these restrictions.
The Unlock PDF tool removes the open password from a PDF when you enter the correct password. If a PDF opens without a password and only has an owner password restricting printing, copying, or editing, the tool can remove those restrictions when you leave the password field blank. It does not crack or bypass unknown passwords, so use it only on documents you own or are permitted to modify.
What to Do After Unlocking
Once you have an unlocked PDF, you can process it with any of the tools on this site:
- Compress PDF — protected PDFs need to be unlocked before they can be compressed
- Merge PDF — combine unlocked PDFs into one document
- Add Page Numbers — stamp page numbers on the unlocked document
- Watermark PDF — add a CONFIDENTIAL or DRAFT watermark to the unlocked copy
- Protect PDF — re-protect with a new password after making changes
Re-Protecting a PDF After Unlocking
If you unlocked a PDF to edit it and now want to re-protect it, simply:
- Make your changes or process the file with other tools
- Go to Protect PDF
- Upload the edited file and set a new password
- Download the re-protected version
This is useful when you receive an annual password-protected report, need to update a few figures, and want to send a newly protected version to stakeholders.
Privacy: What Happens to Your File and Password
The Unlock PDF tool is a server-side tool, unlike our browser-only PDF tools (merge, split, rotate and others). Here is exactly what happens:
- Your protected PDF and the password you type are sent to our server over an encrypted HTTPS connection.
- The server removes the password and returns the unlocked copy.
- The uploaded file and the unlocked copy are deleted after the request. We don't keep copies and no account is needed.
Because the document and its password are processed on a server, think twice before using it for the most sensitive files:
- Financial and legal documents
- Medical records
- Business-sensitive materials
- Personal identification documents
For those, an offline desktop PDF app is the safer choice.
Frequently Asked Questions
Is the unlock tool free?
Yes. Completely free, no account, no watermark on the output.
Does the tool store my password?
The password is sent with your file over HTTPS to our server, where it is used only to unlock the PDF during that request. We don't keep it or the file afterwards.
What if I enter the wrong password?
The tool will show an error and not produce an output. The original protected file is unchanged.
Can I unlock a PDF on mobile?
Yes — the tool works in any modern browser, including Chrome and Safari on iOS and Android.
Try it free — no signup needed
Most tools run in your browser, so your files stay on your device. A few upload the file to our server and delete it afterwards.
