FileLocker is a Windows desktop app that encrypts any file or folder onto a USB drive with AES-256-GCM, plus a standalone unlock page the recipient opens in their own browser — no software install required on their end.
Professionals who hand sensitive files to clients on physical media — lawyers, photographers, accountants, and healthcare providers are the most common, but anyone with the same need fits.
Those tools require your recipient to install matching software to decrypt anything. FileLocker's recipient side is a single HTML file that runs in any browser — nothing to install, nothing to configure.
No. FileLocker operates entirely offline. Your files, passwords, and metadata never touch a server, because there is no server involved.
AES-256-GCM — the same cipher standard approved for top-secret classification, combined with authenticated encryption to detect tampering.
From your password, using Argon2id — winner of the Password Hashing Competition, chosen specifically to resist brute-force attacks.
Stream-based AES-GCM chunking means files of 10GB and well beyond encrypt without memory issues. The real limit is your USB drive's storage capacity.
Yes. Select a folder and FileLocker zips it in memory automatically before encrypting the entire archive as one vault.
No. They open a single HTML file — Unlock_Vault.html — directly in any modern browser.
Chrome, Edge, Safari, and Firefox are all fully supported.
Any — Windows, Mac, or Linux. Only a modern browser is required, not a specific OS.
On Standard, there's no recovery option by design. You can set an optional password hint when creating the vault to help without giving away the password itself.
Nothing. The encrypted vault is unreadable without the correct password — there's no backdoor and no recovery mechanism on Standard.
FileLocker's offline AES-256 encryption is built to support HIPAA's physical media requirements. Always confirm specifics with your own compliance officer before relying on it for a regulated workflow.
The same applies — FileLocker supports GDPR Article 32's call for appropriate technical measures, but compliance is ultimately your organization's responsibility to confirm.
No. There is no master key and no recovery service. Nobody at FileLocker can decrypt your vault on your behalf.
Pro adds white-label branding on the unlock screen, a configurable failed-attempt lockout with recovery key, priority support, and early macOS access. See the full comparison on the Pricing page.
