ROT13 Decoder

Decode ROT13-encoded text back to plain text. The same shift-by-13 operation that encodes also decodes.

    Click Copy to copy the decoded text.

What is ROT13 Decoder?

ROT13 decoding reverses the ROT13 cipher by shifting each letter 13 positions forward ā€” which, in a 26-letter alphabet, returns it to its original position. The encoding and decoding operations are identical.

Use this tool to reveal ROT13-obfuscated text from forums, Usenet posts, puzzle solutions, or any content that was hidden with the ROT13 scheme.

FAQ

Why is ROT13 decoding the same as encoding?
The English alphabet has 26 letters. Shifting by 13 twice brings you back to the start: Aā†’Nā†’A. So the same ROT13 function both encodes and decodes.
I see garbled text with mixed ROT13 and normal text. Can I decode just parts?
This tool applies ROT13 to the entire input. If only part of the text is encoded, the non-encoded parts will become garbled. You'd need to decode them separately.
Is ROT13 the same as ROT13 decoding?
Yes. ROT13 is its own inverse ā€” applying ROT13 twice returns the original text. So encoding and decoding use the exact same operation: shift each letter by 13 positions in the alphabet.
