About ROT47
ROT47 is an extension of ROT13 that works on all 94 printable ASCII characters (codes 33–126), not just letters. Each character is shifted 47 positions.
How it works: characters in the range ! to ~ are shifted by 47 (half of 94), so applying ROT47 twice returns the original text. Spaces and out-of-range characters are left as-is.
ROT47 obscures more character types than ROT13, including digits and symbols. It is still not secure encryption, only for hiding text from direct reading.
FAQ
Can this ROT47 tool both encode and decode?
Yes. This is a single page with a toggle — use Encode mode to transform text, and Decode mode to reverse it. No need for two separate pages.
Is my data sent to a server?
No. ROT47 is processed entirely in your browser. The text you enter never leaves your device.
