About this tool

ROT47 shifts every printable ASCII character (33–126) by 47 positions, and runs entirely in your browser. Applying it twice returns the original text.

Frequently asked questions

How is ROT47 different from ROT13?
ROT13 only rotates the 26 letters, while ROT47 rotates 94 printable ASCII characters including digits and symbols, so more of the text is transformed.
Do I need a separate decode button?
No. ROT47 is its own inverse, so running the same transform on encoded text restores the original.
