About Code & Cipher

Encode and decode messages with ROT13, Caesar cipher, NATO phonetic alphabet, Binary code, and Morse code. All tools are completely free, require no signup, and run entirely in your browser — your text is never sent to any server.

Classical ciphers are the foundation of modern cryptography — and still useful today for light obfuscation, teaching, and puzzle design. ROT13 is the simplest symmetric cipher, widely used to hide spoilers online. Caesar cipher generalises it to any rotation value. NATO phonetic alphabet converts letters to standardised spoken words to prevent miscommunication on radio and phone calls.
