Tool Information
The ROT13 Decoder is a simple tool for revealing messages that have been obscured using the ROT13 cipher. It allows you to decode text that has been encoded with the ROT13 cipher. ROT13 is a substitution cipher that replaces each letter with the 13th letter after it in the alphabet. Our decoder reverses this process, so you can read the original message. This is perfect for quickly revealing messages that have been obscured using this simple substitution cipher, making it easy to read hidden text. The tool is designed to be fast and accurate, and it can decode any text that has been encoded with the ROT13 cipher. It is a simple and effective way to read hidden messages. By using our decoder, you can easily reveal the content of any ROT13-encoded text. Our ROT13 Decoder is a fun and useful tool for anyone who comes across ROT13-encoded text. It is a simple yet effective way to reveal hidden messages and to solve simple puzzles. Whether you are a puzzle enthusiast or just curious about ciphers, our decoder is a great tool to have at your disposal.
ROT13 Decoder Online
Decode ROT13 text back into readable plain text. Runs fully in your browser — fast, private, and secure.
How to Use the ROT13 Decoder
- Paste or type your ROT13 encoded text into the input editor
- Click the "Decode" button to convert it back into plain text
- View the decoded output in the right editor
- Use the copy button to copy the decoded text
💡 Pro Tip: ROT13 encoding and decoding use the same algorithm. Running ROT13 twice on the same text gives you back the original.
What is a ROT13 Decoder?
A ROT13 Decoder is a tool that reverses the ROT13 cipher, which is a simple letter substitution cipher. It replaces each letter with the 13th letter after it in the alphabet. Since the English alphabet has 26 letters, applying the ROT13 cipher twice will return the original text.
Why Use Our ROT13 Decoder?
