PDF Unlocker

Remove owner-password restrictions or strip a known user password from PDF files — batch multiple PDFs at once, entirely in your browser.

Runs privately in your browser — your input is never uploaded or tracked.

Unlock a PDF Online — Remove Password & Restrictions

Remove password protection and restrictions from a PDF with this free, browser-based PDF unlocker. Many PDFs are locked with an owner password that blocks printing, copying, or editing without ever requiring a password to open — this tool strips that lock instantly, no password needed. If a PDF requires a password just to open it, enter the password you already know and the tool removes it, giving you back a normal, unrestricted file.

Unlocking runs entirely in your browser using a WebAssembly build of qpdf, the same engine trusted by many desktop PDF tools, so the full document — including selectable text and vector graphics — comes out unlocked without being flattened into an image. Drop a batch of locked PDFs at once and download them individually or as a single ZIP. This tool does not crack or guess unknown passwords; it only removes a permission-only lock or a password you already have.

How to Unlock a PDF

  1. Add a password if you have one

    If the PDF prompts for a password when opening, type it into the password field. Leave it blank if the PDF only restricts printing or editing.

  2. Drop your PDF files

    Drag one or more locked PDFs onto the drop zone, or click to browse and select them.

  3. Let it unlock

    Each file is decrypted in your browser — you'll see a live status per file, including a clear message if a password is missing or wrong.

  4. Download the results

    Download each unlocked PDF individually, or grab all of them at once as a ZIP archive.

Features of the PDF Unlocker

  • Removes owner-password restrictions

    Strip print, copy, and edit locks with no password required — the same as what any PDF viewer can already read.

  • Removes a known user password

    Enter a password you already have to remove the requirement to open the file in future.

  • Preserves text and vector quality

    Uses a real PDF decryption engine (qpdf, compiled to WebAssembly), not page rasterization — the output keeps selectable text and sharp vectors.

  • Batch multiple PDFs

    Drop a whole folder of locked PDFs and unlock them all in one pass.

  • Runs fully in-browser

    Your PDFs and passwords never leave your device — nothing is uploaded to a server.

Frequently Asked Questions

How do I remove a password from a PDF?

If you know the password, type it into the password field before dropping the file — the tool decrypts it and gives you back an unrestricted PDF. If the PDF only blocks printing or editing (no password needed to open it), leave the field blank; it unlocks automatically.

Can this crack or guess a PDF password I don't know?

No. This tool only removes a password you already know, or an owner-only restriction that doesn't require a password to open the file at all. It does not perform password cracking or brute-forcing.

Will the unlocked PDF still have selectable text?

Yes. Unlike tools that flatten pages into images, this uses a real PDF decryption engine (qpdf via WebAssembly), so text stays selectable and vector graphics stay sharp.

Is my PDF or password uploaded anywhere?

No. Everything runs locally in your browser using WebAssembly — your files and any password you type never touch a server.

Can I unlock several PDFs at once?

Yes. Drop multiple files together; each is unlocked independently and you can download them one by one or together as a ZIP.
