FusionPDF removes password protection from PDFs you own (and have the password for) entirely in your browser using PDF.js. Enter the password, and the tool returns a fully accessible, unencrypted copy. No file is uploaded to any server. The PDF specification supports two distinct password types, and this tool handles both: user passwords that block opening, and owner passwords that restrict permissions.
Drop your password-protected PDF into the upload area. The options panel appears with a password field. Type the current password and press Enter or click "Unlock and download." The tool loads the encrypted file into browser memory using PDF.js, applies the password to decrypt it, then re-saves the document without encryption using pdf-lib. The unlocked copy downloads to your device immediately.
The original protected file on your device is not modified. You get a new, clean copy alongside it. This is useful when you want to keep the protected original and also have an accessible working copy.
A user password (open password) prevents the document from opening at all without the password. If you try to open the PDF and get a prompt before seeing any content, it has a user password. This tool removes it when you enter the correct password.
An owner password (permissions password) allows the file to open freely but restricts actions: printing, copying text, and editing may be disabled. These PDFs often open without any prompt. PDF.js can frequently remove owner-only restrictions without requiring the owner password, because the content encryption key for permissions-only protection uses a weaker derivation method defined in the older PDF specification (PDF 1.x). If your PDF opens but won't let you print or copy, try running it through this tool with an empty password field.
There is no practical way to recover an AES-256 password if you've lost it. The encryption standard is specifically designed so that without the key, the content cannot be read in any reasonable timeframe, even with significant computing resources. This applies to any tool, not just this one.
The honest answer is: keep a secure record of passwords you set for documents you'll need again. A password manager is the right place for this. If you protected the document yourself and can still access the original unprotected source file, re-protect it with a new password using the Protect PDF tool.
If someone else set the password and you don't have it, you cannot access the content. No legitimate tool can bypass a properly implemented AES-256 password without the key.
Yes. "Unlock PDF," "remove PDF password," "decrypt PDF," and "unsecure PDF" all describe the same operation: reading the encrypted file using the correct password and saving a new copy without any password requirement. Different tools and search queries use different terminology, but the result is identical.
The output of this tool is a standard, unencrypted PDF. It opens in any PDF viewer without a prompt and supports all standard operations including printing, text selection, and annotation, assuming the original document's content supports those actions.
The document you're unlocking presumably contains something sensitive, otherwise it wouldn't have been password-protected in the first place. Medical reports, legal contracts, financial statements, and HR documents are exactly the types of files commonly protected with PDF passwords.
With a server-based unlock tool, two things travel to a third-party server: the protected document and its password. Even if the server deletes both immediately, the unencrypted content is exposed in transit and in memory on infrastructure you don't control. With browser-based unlocking, both the document and the password remain on your device throughout the entire operation.
