Text Encryptor
FreeEncrypt text with AES-256-GCM using a password. Runs entirely in your browser — nothing is sent to any server.
AES-256-GCM
Military-grade encryption with authenticated encryption mode. Prevents tampering.
100% Browser-Based
Your text and password never leave your device. WebCrypto API handles all cryptography locally.
PBKDF2 Key Derivation
200,000 iterations stretch your password into a cryptographic key, slowing brute-force attacks.
What is Text Encryption?
Text encryption converts readable plaintext into unreadable ciphertext using a password and the AES-256-GCM algorithm, ensuring only someone with the correct password can read the original text.
Why Encrypt Text?
Encrypt sensitive notes, API keys, passwords and messages before storing or sharing them. Even if the encrypted text is intercepted, it cannot be read without the password.
