File Encryption (Password-Protect Any File)
Encrypt any file with a password before sharing or storing it — AES-256-GCM in your browser. Decrypt it here later to get the original file back, name and all.
How to use
- 1Choose a file and enter a strong password, then press Encrypt to download a .enc file.
- 2To open it, drop the .enc file here, enter the password and press Decrypt.
How it's calculated
Same as text encryption: PBKDF2-SHA-256 (600,000 iterations) → AES-256-GCM. The original filename is stored inside the encrypted data.
Frequently asked questions
Are my files uploaded?
No — everything happens locally in your browser. Nothing leaves your device.
How large a file can I encrypt?
Files up to a few hundred MB work in most browsers; very large files depend on your device's memory.
Can other tools open the .enc file?
It's a documented AES-GCM format but meant to be decrypted with this tool. For long-term archives, also consider 7-Zip with AES-256.
