Unlock PDF

Unlock PDF is an online tool that runs entirely in your browser to remove password protection from PDF files. As long as you know the open or permission password, you can enter it to decrypt the file and get a PDF that opens directly without a password, with printing, copying, and editing restrictions removed.

Key Features

• Remove the open password: after entering the correct password, the exported file no longer requires one to open.
• Clear permission limits: also removes restrictions on printing, copying content, and editing.
• Batch processing: add multiple PDFs at once, unlock them in a queue, and stop at any time.
• Local and secure: decryption happens in your browser; files and passwords are never uploaded to a server.
• Flexible downloads: download results one by one, or package multiple files into a single ZIP.
• Preview before unlocking: check file contents beforehand to confirm it is the right PDF.
• Clear error messages: automatically detects unencrypted files, wrong passwords, and unsupported encryption.

Use Cases

• You know the password but want a copy that opens without entering it every time for frequent viewing.
• You have a permission-restricted PDF that opens but cannot be printed, copied, or edited, and need those limits removed.
• You have many encrypted documents and want to remove passwords in batch before archiving or delivery.
• You need to send a PDF to someone without the password, such as a colleague, client, or print shop.

How to Use

1. Click the upload area or drag PDFs into it; you can select multiple files at once.
2. Enter the open or permission password that you already know.
3. Click "Unlock" and the tool processes each file in turn, showing progress.
4. When finished, download the unlocked PDFs individually or as a ZIP package.

About Open and Permission Passwords

A PDF usually has two kinds of passwords: an open password restricts viewing and must be entered to see the content, while a permission password restricts printing, copying, and modifying even though the file opens directly. This tool handles both — provide any one correct password and it removes the corresponding protection.

FAQ

Q: Is this tool free?

A: Yes, unlocking and batch processing are completely free, with no registration or sign-in required.

Q: Are my files and password safe?

A: Yes. Decryption runs entirely in your browser, so neither the PDF files nor the password you enter are ever uploaded to a server.

Q: Can it crack a password I have forgotten?

A: No. This tool only removes a password you already know; it cannot crack or recover lost passwords.

Q: Why do I see "Incorrect password" or "This encryption type is not supported"?

A: It means the password is wrong, or the file uses an encryption method the tool does not support yet. Please check the password and try again.

Q: Does it work on mobile devices?

A: Yes. The page is responsive, so you can upload, unlock, and download files on phones and tablets as well.
