Password-protect any files with military-grade AES-256 encryption — right in your browser. No uploads. No servers. Nothing leaves your device.
No compromises. Every feature was designed with your security in mind.
The same encryption standard used by banks and governments. Your files are unreadable without the correct password.
Everything happens on your device. Your files never leave your computer — not even for a millisecond.
Files are compressed before encryption, saving up to 80% on text, docs and code files.
Lock an entire folder's worth of files into a single .locked file with one click.
200,000 PBKDF2 rounds make each password guess extremely slow. Hackers can't brute-force their way in.
You can access FolderLock from any browser — Chrome, Firefox, Safari, or Edge. Just open the website URL and it works instantly, no installation or download required.
Three simple steps to protect your files.
Drag and drop any files — documents, images, videos, code — or click to browse. Add as many as you need.
Choose a strong password. The strength meter guides you. Confirm it, name your vault, and hit Encrypt.
A single .locked file downloads to your device. Store it anywhere — cloud, USB, email.
No sign-up. No waiting. Start encrypting immediately.
