ROT13 Decoder
Decode ROT13-encoded text — since ROT13 is self-inverse, this runs the exact same transformation as the ROT13 Encoder.
How to Use ROT13 Decoder

Frequently Asked Questions
It isn't — ROT13 is self-inverse (shifting by 13 twice returns to the original 26-letter alphabet), so this decoder runs the exact same transformation as the ROT13 Encoder tool.
Then it likely wasn't ROT13-encoded in the first place, since running ROT13 on genuine ROT13 output always restores the original text exactly.
No — only letters A-Z/a-z are shifted; numbers, punctuation, and spaces pass through unchanged, same as the encoder.
No — the transformation happens entirely in your browser.
