Remove PDF Password
Enter the password to unlock your PDF and download a protection-free copy. Everything runs in your browser: your file never leaves your device.
The unlocked PDF preserves visual layout but pages are rasterized: a necessary trade-off for browser-based decryption. You need to know the original password; this tool does not crack or brute-force passwords.

How to remove a password from a PDF online for free
AlteredIdea's PDF Password Remover decrypts password-protected PDF files directly in your browser. You provide the password that was used to lock the file: the tool validates it, decrypts the PDF in memory, and downloads an unlocked version. At no point is your file or password sent to any external server.
This works for standard PDF user passwords, which are the kind that prevent opening the file without a password prompt. The underlying decryption is handled by pdf-lib, a widely-used open-source PDF library that runs entirely in the browser.
Step-by-step: unlock a password-protected PDF
- 1Upload your locked PDF
Drag the file onto the upload zone or click to browse. The file is loaded into browser memory only. - 2Enter the PDF password
Type the password that was used to protect the file. The eye icon lets you reveal it as you type. - 3Click Unlock & Download PDF
The tool validates the password by attempting to decrypt the file. If the password is correct, decryption succeeds. - 4Download the unlocked file
A new file named unlocked_[original-name].pdf is downloaded to your device, free of password protection.

Frequently Asked Questions
- How do I remove a password from a PDF for free?
- Upload your locked PDF to AlteredIdea's PDF Password Remover, enter the password used to protect it, and click Unlock. The tool verifies the password locally and downloads an unprotected copy to your device.
- Is the password sent to any server?
- No. Your password and your PDF are processed entirely in your browser. Neither the file nor the password is ever transmitted to a server.
- What happens if I enter the wrong password?
- The tool will immediately show an error and will not produce any output. You can try again with the correct password.
- What types of PDF encryption does this tool support?
- The tool uses pdf-lib which supports the standard PDF user-password encryption found in most password-protected PDFs, including those created with Adobe Acrobat, Preview on Mac, and other common PDF editors.
- Does this work on PDFs with owner/permissions passwords?
- This tool removes user open passwords. Owner passwords (permissions passwords that restrict editing/printing but not opening) behave differently: if the PDF opens without a password but has restrictions, use a desktop PDF editor to modify permissions.
- Are my files stored anywhere?
- No. The file is loaded into your browser's memory only for the duration of the unlock operation and is never saved to any server or cloud storage.
- Does this tool work on mobile?
- Yes. It works in any modern mobile browser on Android or iOS.
- Why can't I just open the PDF in a viewer and print it?
- That approach works but requires extra steps. This tool gives you a clean, properly unlocked PDF file that any application can open directly: without needing a password each time.
- Can I remove a password from a PDF on a Mac without software?
- Yes. Open AlteredIdea's PDF Password Remover in Safari or Chrome on your Mac, upload the password-protected PDF, enter the password, and click Unlock. The unlocked file downloads to your Mac without installing any software. No file is ever sent to a server.
- What should I do if I forgot the PDF password?
- This tool requires you to know the password: it validates it and decrypts the file, but it cannot crack or guess unknown passwords. If you have forgotten the password, you will need to contact whoever created the PDF, or use specialist password recovery software on your own device.
