About the ROT47 Encoder & Decoder
Encode and decode text with ROT47, which shifts all printable ASCII characters (not just letters) by 47 places.
Unlike ROT13, ROT47 also changes numbers and punctuation, and the same operation decodes.
A fun way to obscure text in forums and puzzles.

Frequently asked questions
- How is ROT47 different from ROT13?
- ROT13 only rotates letters, while ROT47 rotates the full printable ASCII range, so digits and symbols change too.
- Is ROT47 secure?
- No. Like ROT13, it only obscures text and is trivial to reverse.
- Is my data uploaded?
- No. Everything runs in your browser.
