ROT47 Encoder/Decoder — Apply ROT47 Cipher Online

ROT47 extends the ROT13 idea to all 94 printable ASCII characters (! through ~), rotating each character by 47 positions. Like ROT13, applying ROT47 twice recovers the original text.

Common Use Cases

  • Obfuscating text including punctuation and digits
  • Creating simple reversible text transformations

Frequently Asked Questions

How is ROT47 different from ROT13?

ROT13 only rotates letters (A–Z, a–z) by 13. ROT47 rotates all printable ASCII characters (!, ", #, ... ~) by 47, so it also transforms digits and punctuation.
