ROT13 Encoder

ROT13 Encoder is a free online tool that instantly converts text into ROT13 format by applying a basic alphabet substitution cipher. Simply type or paste your text into the input box and press the Encode button to change any alphabetic characters to their ROT13 equivalents, by replacing the original character with the 13th letter in the alphabet in most cases. Our simple ROT13 Encoder is most useful for web developers, coders, programers, students, puzzle-solvers, or anyone interested in basic text encodings. Use it to encode messages and words, Encode spoilers, make simple text puzzles, or to learn how simple text encoding algorithms work. Because this encoding algorithm does not change the case of individual characters, converting ROT13 text to plain text (or vice versa) is just as easy as using our ROT13 Decoder.
