ROT13 Encoder

Rotate letters by 13 positions to encode text.

Plaintext

Note: ROT13 rotates each letter by 13 positions. Because 13 is exactly half of 26, applying ROT13 twice returns the original text, so the same operation both encodes and decodes.

What Is a ROT13 Encoder?

The ROT13 Encoder tool rotates every letter by 13 positions in the alphabet. Because 13 is exactly half of 26, applying ROT13 twice restores the original text, so the same operation both encodes and decodes.

How to Use This ROT13 Encoder

1
Enter TextType the text you want to encode.
2
EncodeClick 'Encode' to produce the ROT13 output.
3
Copy ResultClick the copy button to save the encoded text.

Frequently Asked Questions

Rotating by 13 and then by 13 again rotates by 26, returning every letter to its original position. So one operation handles both directions.

No. It is obfuscation often used to hide spoilers or puzzle answers, not real encryption.
