Frequently Asked Questions

What is Unlock PDF?

Unlock PDF is a free, browser-based tool on TitanFile that lets you remove password protection from a PDF you own. Enter the password once to save an unlocked copy — no recurring prompts. Everything runs locally on your device — no files are ever uploaded to any server.

How do I use Unlock PDF?

Open the Unlock PDF page, add your file or enter your data, adjust any settings, then click the action button. Your result is ready instantly — no sign-up or installation required.

Are my files private?

Yes — all processing happens entirely in your browser using JavaScript. Your files and data never leave your device and are never uploaded to any server. We cannot see your files even if we wanted to.

Does this work offline?

Once the page has loaded, Unlock PDF works without an internet connection. You can install it as a PWA to your home screen for instant offline access.

Is there a file size limit?

There is no server-side limit because everything runs locally in your browser. The practical limit is your device's available memory. Most modern devices handle files up to several hundred MB without issue.

Why is this free?

TitanFile is ad-supported and passion-driven. We believe powerful tools should be accessible to everyone. Unlock PDF — like every tool on TitanFile — will always be free with no paywalls, watermarks, or hidden fees.
