ROT13 Decoder
Decode ROT13-encoded text back into its original, readable message. (Same as Encoder)
The ROT13 Decoder reverses the ROT13 cipher, shifting each letter back 13 places to reveal the original message. This is a common utility for easily decoding lightly obscured text. Decode ROT13 text instantly!
Enter ROT13 encoded text to decode. ROT13 shifts each letter by 13 positions. Example: Uryyb → Hello

How ROT13 Works:
- Each letter is shifted 13 positions in the alphabet
- A→N, B→O, C→P ... M→Z, N→A, O→B ... Z→M
- Numbers, spaces, and punctuation remain unchanged
- ROT13 is its own inverse: encode twice to get original text
