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 your clients receive confidential files from you — FileLocker was built for your workflow.
"I deliver case files, contracts, and evidence to clients knowing that even if the USB drive gets lost — nobody can read what's inside without the password."
"Tax season means handing tax returns and financial statements to clients. FileLocker makes that handoff completely private — and my clients don't need to install a thing."
"My clients' wedding photos are private until they personally unlock them. No cloud service involved. No way for anyone else to access them first."
"Patient records delivered on a drive, protected the right way. My clients open them in their browser without downloading anything."
Upload your firm's logo, set your brand color, and add your firm's name. When your client opens the USB drive, the unlock screen shows your identity — not FileLocker's. It looks like your own proprietary secure delivery system.
No software download. No account creation. No tech support call. If your client has Chrome, Edge, Safari, or Firefox — they can open their files.
The entire process — locking and unlocking — happens on the physical devices. No file or password ever touches a server. Because no server is involved.
Check one box and FileLocker automatically deletes the original unprotected file from your computer after locking. Nothing sensitive remains.
Optionally hide the real name of your document so the USB drive reveals nothing — not even what kind of file is on it.
Documents, folders, videos, archives — FileLocker handles files of any size without slowing down or breaking a sweat.
Add an optional hint when you set the password. Your client sees it on the unlock screen if they need a reminder — without revealing the password.
Not sure what password to use? Let FileLocker generate a strong, random password automatically. Save it in your password manager before you click Lock.
FileLocker uses AES-256 — the encryption standard approved by the US government for classified information. It is not a marketing claim. It is a mathematical guarantee. Without the exact password, the files are completely unreadable — even to us.
Your password is not stored as-is. FileLocker transforms it using Argon2id — a system designed to make automated password-guessing attacks computationally impossible, even on modern hardware.
Unlocking happens entirely inside your client's browser. No file, no password, and no document metadata ever travels to any server — because no server is involved at any point.
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 — and that is the whole point. Your client opens one file in their web browser and types a password. Nothing downloads. Nothing installs. No account required. If they can visit a website, they can open their documents.
Nothing — and this is exactly what FileLocker is for. The files on the drive are protected with military-grade encryption. Without the correct password, whoever finds the drive cannot read a single byte of the contents. Mathematically guaranteed.
Because FileLocker works completely offline with no servers involved, there is no password recovery option. This is a security feature, not a limitation — a recovery system would mean someone else could access your files. We strongly recommend using the built-in password generator and saving the result in your password manager before clicking Lock. The optional hint feature also helps your client remember without giving away the password itself.
If they can open a website and type a word, they can open their files. The unlock screen is designed for non-technical clients. It has one field, one button, and your firm's branding on the screen.
The desktop app for locking files runs on Windows 10 and 11. Your clients can unlock files on Windows, Mac, or Linux — any computer with a modern browser. macOS sender support is on our roadmap.
Share it separately from the USB drive — call them, text them, or tell them in person. Never write the password on the drive or include it in the same package. Keeping the key separate from the lock is what makes this genuinely secure.
Yes. Select any folder and FileLocker automatically bundles everything inside it before locking. Your client receives the complete folder structure when they unlock.
No. FileLocker operates entirely offline. No file, no password, and no document name ever touches any server. There is no cloud component and no internet connection required at any point — for you or your client.
There is no free trial. Instead, watch our 90-second demo video to see the complete workflow before you buy. If FileLocker doesn't work exactly as described within 30 days, contact us for a full refund — no questions asked.
You pay $29 once. You own FileLocker forever. No annual renewal. No subscription. No email reminding you to update your billing. Lifetime updates are included.
Start delivering sensitive files the way professionals should — encrypted, clean, and with zero friction for the person receiving them.
