Batch Remove Password

Purpose

Strip owner-password permission restrictions (e.g., "no printing", "no copying", "no editing") from a PDF while preserving the open password (if any). Requires the owner password, or works directly when permissions allow. Runs locally via qpdf-wasm; no upload, no watermark, free. Use it to unlock viewable but copy/print-restricted PDFs — common in ebooks and some academic papers.

Steps

1. Drag or pick a PDF
2. First use downloads the ~2MB qpdf engine
3. Review detected restrictions (e.g., "Printing not allowed", "Copying not allowed")
4. Enter the owner password if required; skip if not
5. Click "Process"
6. The tool strips permission restrictions and outputs an unrestricted PDF
7. Download with the "-unlocked" suffix

FAQ

How is this different from Decrypt?

Decrypt removes the open (user) password so the PDF can be opened without one. Remove Password only strips the owner-password permission restrictions (print/copy/edit); the open password remains. Pick based on what's actually blocking you.

Is removing legitimate copy protection allowed?

Technically the tool can process any spec-compliant owner-password restriction, but please ensure you have legal rights — circumventing copyright protection or someone else's encryption may carry legal consequences. Use this tool to unlock your own restrictions or content you're lawfully permitted to modify.

Will my file be uploaded?

No. qpdf operates in your browser; the PDF and password never leave your device.

What if I don't know the owner password?

Some PDFs (with weak/missing strong encryption) allow permission modification without the password, and qpdf will attempt the operation. For AES-256-encrypted PDFs without the owner password, it's technically not bypassable.

Can I print/copy normally after stripping?

Yes. The processed PDF opens in any reader and allows print/copy/edit subject to that reader's own permissions.

Use cases

• Unlock an ebook's print restriction to print a specific page
• Strip a paper's copy restriction to quote passages
• Lift an internal PDF's edit restriction to add annotations
• Remove a scanned contract's print restriction to keep a physical copy
• Lift a textbook's text-extraction restriction for note-taking

Tip

If the PDF has both an open password and permission restrictions, do it in two steps: first Decrypt to lift the view block, then Remove Password to lift permissions. Or just use Decrypt — full decryption removes both at once.
