Why Luleit's PDF Protection is Different

Frequently Asked Questions

Where does my PDF go when I protect it?+

Nowhere. The processing happens in your browser using JavaScript — your PDF never touches our servers, never gets uploaded, never gets stored. Once you close the tab, the file is gone from memory; we have no copy. There is nothing for anyone to subpoena, breach, or sell.

Is this PDF protection tool really free, with no catch?+

Yes — no signup, no email required, no watermarks, no page limits, no daily quota, and no upsell for a paid tier. The tool runs entirely in your browser using free, open-source JavaScript libraries, so we have no server costs to recover. Your privacy IS the business model: we collect nothing because we have no use for it.

Is this the same as password-protecting a PDF?+

No — this restructures the file to discourage editing without requiring a password to open. For true password-based encryption, use a desktop tool like Adobe Acrobat or qpdf. The advantage of this tool is recipients can still open the file normally.

[Review Testimonials]

"Luleit is a lifesaver for legal docs. Knowing that my PDFs are processed entirely locally in the browser and never uploaded is a massive compliance win. No file leaks, no account needed, super fast."

Sarah K.

"Outstanding speed and absolute privacy. I use it daily to compress medical records. Extremely secure and HIPAA compliant by design!"

David M.

Healthcare Administrator

"Unbelievably simple. No sign-up, no watermark, and the Chrome extension makes it a one-click launch from my browser toolbar. Best PDF utility out there."
