How to Remove Password From PDF — Free, Online

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 in your browser.

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 entirely in your browser using pdf-lib. Your file never leaves your device.

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 — the tool cannot bypass security, it simply uses your provided password to open the file and then saves it without encryption.

Step 3 — Click "Unlock PDF" and download

Click Unlock PDF. The tool opens the PDF with your password, re-saves it without any 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?

Technically, no — not using this tool, and not ethically for someone else's protected document.

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
  • Are illegal to use on PDFs you don't own
  • 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 you've authenticated with the correct password. For permissions-restricted PDFs (where you can open but not print or copy), a different approach is needed.

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 — many protected PDFs can't be compressed without unlocking first
  • 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:

  1. Make your changes or process the file with other tools
  2. Go to Protect PDF
  3. Upload the edited file and set a new password
  4. 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: Why Browser-Based Matters

When you unlock a PDF through a cloud service, your protected document — and the password you enter — are transmitted to someone else's server. You're trusting that server not to log, store, or misuse your document and your password.

The Unlock PDF tool runs entirely in your browser. The password you type never leaves your device. The PDF content never leaves your device. The entire cryptographic operation happens locally using WebAssembly.

This matters especially for:

  • Financial and legal documents
  • Medical records
  • Business-sensitive materials
  • Personal identification documents
