FileLocker encrypts any file onto a USB drive with AES-256-GCM security. Your client opens one HTML file in their browser and the download starts instantly — no software, no account, no internet required.
Three steps, no internet connection required at any point.
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.
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.
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.

If you regularly hand files to clients on physical media, FileLocker was built for you.
"I deliver case files and evidence to clients on USB without worrying about the drive falling into the wrong hands."
"My wedding shoots stay protected until the client personally unlocks them. No more plain USBs at risk."
"Tax returns and financial statements go to my client knowing only they can ever open them. Nobody else, ever."
"Patient records delivered on physical media, encrypted to standards built for HIPAA workflows. No cloud risk."
"Testimonial coming soon — be our first reviewer."
"Testimonial coming soon — be our first reviewer."
"Testimonial coming soon — be our first reviewer."
The same standard used by banks, governments, and the US military. Unreadable without the password — that's mathematics, not a claim.
Your client opens a single HTML file in their browser. No download, no account, no support call. It just works.
No internet required, no cloud servers, no data harvesting. Everything happens locally on the physical devices involved.
Recipients can unlock on Windows, Mac, or Linux using Chrome, Edge, Safari, or Firefox. If they have a browser, they can unlock.
Stream-based AES-GCM chunking means even massive video files and datasets encrypt smoothly without breaking a sweat.
Customize the recipient's unlock screen with your firm's logo and colors — included in every license.
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.
Everything included. No subscriptions. No monthly fees. No surprises.
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.
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.
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.
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.
There's no recovery option by design — this is what makes it secure. You can add an optional hint when setting up the vault.
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.
We don't offer a free trial, but we provide a strict 30-day no-questions-asked money-back guarantee so you can try it completely risk-free.
Start delivering sensitive files the way professionals should — encrypted, clean, and with zero friction for the person receiving them.
