Decrypt a .filex file
Received an encrypted .filex container? Unlock it here. Decryption runs entirely on your device, so the file and its contents never touch a server.
Free · runs 100% in your browser · no upload, no account
How it works
- Open the Decrypt tool and drop in the
.filexfile. - Enter the password the sender gave you.
- FileX verifies the AES-256-GCM authentication tag; if the password is wrong or the file was altered, it refuses rather than returning corrupt data.
- Download your original file, byte-for-byte identical to the source.
Works with single files and archives
FileX reads both container types: FLX1 for a single encrypted file and FLX2 for a multi-file archive. You get the same local, zero-upload guarantee either way.
Frequently asked questions
Do I need the same app the sender used?
No — any FileX instance decrypts a .filex file. You only need the file and the password.
Why does it say the password is wrong when I think it is right?
AES-256-GCM authenticates every byte. A single wrong character in the password, or a file corrupted in transit, fails the integrity check. Re-check the password and re-download the file.
