Is this PDF unlocker really local?

Yes. The PlainBench Local PDF Unlocker processes your PDFs directly in your browser using JavaScript. The file is not uploaded to any server, and there are no accounts, sign-ups, or paywalls.

Can this tool crack someone else’s password-protected PDF?

No. This tool is not a password cracker. It only unlocks PDFs you are already able to open yourself. For PDFs with an open password, you must supply that password. For PDFs with only printing/copy restrictions and no open password, it rebuilds a clean, unrestricted version for your personal use.

What happens to my PDF after unlocking?

After you unlock your PDF locally, the tool regenerates a new unlocked copy in your browser and immediately offers it as a download. Nothing is stored or sent to any external server.

Will text still be searchable after unlocking?

To keep this tool fully local and compatible across browsers, it rebuilds each page as a high-quality image in a new PDF. That means text may not be selectable or searchable in the unlocked copy, but all content will be preserved visually.

Local PDF Unlocker – Remove Password from Your Own PDFs

Most PDF unlockers are paywalled, limited, or risky. This PlainBench tool is different: it’s a local file password remover that runs entirely in your browser. Drag and drop a PDF you own, enter the password if needed, and download a new, unlocked copy with no upload, no sign up, and no page limits.

All online versions: paywalled, limited, unsafe. Your version: local & unlimited.

This Local File Password Remover uses PDF.js and jsPDF inside your browser to rebuild a new PDF without the original password or restrictions. It is intended only for PDFs you own or are fully authorized to modify.

1. Add your locked PDF

Drag and drop a PDF anywhere inside the box, or click the button to pick a file. Files are processed locally and are never uploaded to any server.

Drag & drop your PDF here

…or click to browse from your device

Max size: depends only on your browser & memory, no artificial limits.

2. Enter password (if needed) and unlock

For PDFs that ask for a password when you open them, enter that password here. For PDFs with only print/copy restrictions (no open password), you can usually leave this blank.

Waiting for a PDF…

3. Download your unlocked copy

After processing, you’ll get an unlocked PDF built from the original pages. This removes the open password and most print/copy restrictions. The unlocked copy is for personal use only.

Legal reminder: only use this PDF unlocker on documents you own or are explicitly allowed to modify. Do not use it to bypass protections on copyrighted or confidential files without permission.

Why a local PDF unlocker matters

Most “free” PDF unlockers:

Upload your private PDFs to a remote server
Add page limits, watermarks, or hidden fees
Require accounts or emails to download

The PlainBench approach:

Browser-only: uses PDF.js + jsPDF directly in your browser
No upload: your file never leaves your device
No limits: no artificial page count or file size caps
No accounts: just drop a PDF and unlock

What this PDF unlocker can and can’t do

Can do:

Open PDFs using a password you already know
Rebuild a new PDF that no longer asks for a password
Strip many print/copy restrictions by creating a fresh file
Handle multi-page PDFs locally with no upload

Cannot do:

Guess or crack unknown passwords
Bypass legal or contractual restrictions you are bound by
Guarantee selectable/searchable text (pages are re-rendered as images)

How it works under the hood

For the curious:

PDF.js loads your PDF in memory (with the password if required) and renders each page to an off-screen canvas.
jsPDF then captures those canvases as high-quality images and assembles a new PDF, page-by-page.
The resulting PDF has no password and generally no copy/print restrictions, since it’s a brand-new file.

This approach keeps everything fully client-side and compatible with modern browsers, while avoiding backend servers entirely.

Pair this with other PlainBench file tools
