ROT13 Encoder

Encode your text using the simple, reversible Caesar cipher known as ROT13.

Home ROT13 Encoder
The ROT13 Encoder applies a simple letter substitution cipher, shifting each letter 13 places down the alphabet. A quick utility for light obfuscation or solving puzzles. Since ROT13 is its own inverse, the encoder acts as a decoder too. Encode/Decode ROT13 now!

Enter text to encode with ROT13. ROT13 shifts each letter by 13 positions. Example: Hello → Uryyb
