About ROT13 & Morse Code

ROT13 is a simple substitution that shifts letters by 13. Applying ROT13 twice returns the original text.

Morse Code represents characters with dots and dashes (e.g., A = .-).

🧪 Example

Input: HELLO

  • ROT13: URYYB
  • Morse: .... . .-.. .-.. ---

ROT13 & Morse — FAQ

Does this upload my text?

No. All conversions run locally in your browser.

How do I separate Morse letters and words?

Use a single space between letters and a slash / between words, e.g., .... . .-.. .-.. --- / .-- --- .-. .-.. -...

Why are numbers or punctuation not converting?

ROT13 only transforms A–Z letters. Morse supports 0–9 and common punctuation; anything unsupported is left as-is.
