How it works

Simple for you. Effortless for them.

Three steps, no internet connection required at any point.

01 — YOU

Select your file. Set a password.

Open FileLocker on your Windows PC, plug in a USB drive, and choose any file or folder — up to 10GB and beyond. Set a strong password and FileLocker encrypts it in seconds.

AES-256-GCM · ARGON2ID KEY DERIVATION
02 — HANDOFF

Hand the USB to your client.

FileLocker writes the encrypted vault and a standalone unlock page to the drive. Hand it over in person — no internet needed. If it's lost, the contents stay unreadable.

DRIVE LOCKED · READY TO DISTRIBUTE
03 — YOUR CLIENT

Open one file. Get their files.

They plug in the USB, open Unlock_Vault.html in any browser, type the password, and their file downloads directly. No install, no account, no internet.

Who it's for

If you regularly hand files to clients on physical media, FileLocker was built for you.

Healthcare

Healthcare Providers

"Patient records delivered on physical media, encrypted to standards built for HIPAA workflows. No cloud risk."

Features

Everything you need. Nothing you don't.

AES-256-GCM Encryption

The same standard used by banks, governments, and the US military. Unreadable without the password — that's mathematics, not a claim.

Zero Install for Recipients

Your client opens a single HTML file in their browser. No download, no account, no support call. It just works.

100% Offline Operation

No internet required, no cloud servers, no data harvesting. Everything happens locally on the physical devices involved.

Cross-Platform Unlocking

Recipients can unlock on Windows, Mac, or Linux using Chrome, Edge, Safari, or Firefox. If they have a browser, they can unlock.

Files Up to 10GB and Beyond

Stream-based AES-GCM chunking means even massive video files and datasets encrypt smoothly without breaking a sweat.

Password Hints & Strength Meter

Set an optional hint to help your recipient remember without revealing the password. A built-in meter checks vault strength.

Why FileLocker

Not all USB delivery is equal.

Without FileLocker
  • Anyone who finds the drive reads everything instantly
  • Recipient needs WinRAR, 7-Zip or VeraCrypt installed
  • Outdated interfaces confuse non-technical clients
  • Cloud alternatives expose data to third-party servers
  • If the USB is lost, all files are fully exposed
With FileLocker
  • AES-256 encrypted — unreadable without the password
  • Opens in any browser — zero install for recipient
  • Clean modern interface anyone understands immediately
  • 100% offline — no servers, no cloud, no exposure
  • Lost USB means nothing — the data is mathematically locked
Security

Military-grade is not marketing. It's mathematics.

FileLocker uses AES-256-GCM, the algorithm standard approved for top-secret data. Keys are derived with Argon2id, winner of the Password Hashing Competition, built to resist brute-force attacks even on modern GPU hardware.

Decryption happens entirely inside the recipient's browser using the Web Crypto API. No file, password, or metadata ever touches a server — because no server is involved.

The Risk of Not Buying

Handing over unencrypted USB drives is a massive liability.

If you lose a standard USB drive containing sensitive client documents, medical records, or financial statements, you are legally liable for a data breach. FileLocker mathematically guarantees that lost drives remain completely unreadable to anyone who finds them. The peace of mind is worth $29.

FAQ

Questions answered.

Does the recipient need to install any software?+

No. The recipient opens a single HTML file in any modern browser — Chrome, Edge, Safari, or Firefox. No download, no account, no installation of any kind.

What happens if the USB drive is lost or stolen?+

Nothing. The encrypted vault on the drive is unreadable without the correct password. There's no backdoor and no recovery mechanism — which is exactly what makes it secure.

Does FileLocker work on Mac?+

The desktop encryption app currently runs on Windows 10 and 11. Recipients on Mac can seamlessly unlock files — any browser on any operating system works for unlocking.

What if I forget the password?+

There's no recovery option by design — this is what makes it secure. You can add an optional hint when setting up the vault.

Is my data stored on any server?+

No. FileLocker operates entirely offline. No file, password, or metadata ever touches a server. There are no cloud accounts and no internet connection required at any point.

Is there a free trial or money-back guarantee?+

We don't offer a free trial, but we have a 90-second demo video showing exactly how it works. Additionally, we provide a strict 30-day no-questions-asked money-back guarantee.

Your clients deserve better than a plain USB.
