About ROT13 Text
ROT13 Text applies the classic ROT13 cipher to letters in text. Each Latin letter is rotated by 13 positions, while digits, spaces, punctuation, and other characters stay unchanged. Applying ROT13 twice returns the original text.
How It Works
Use the tool in three quick steps:
- Paste the text - Add the plain text or ROT13 text you want to convert.
- Run the cipher - Click Apply ROT13 to rotate every letter by 13 positions.
- Copy the result - The same action can encode plain text or decode ROT13 text.
Basic Examples
-
Encode plain text with ROT13
Input Text: Hello, World! Output: Uryyb, Jbeyq!
-
Decode ROT13 text
Input Text: Uryyb, Jbeyq! Output: Hello, World!
-
Keep non-letters unchanged
Input Text: ROT13 123?! Output: EBG13 123?!
