Text Scrambler (ROT13)

About Text Scrambler (ROT13) Tool

Our text scrambler tool uses the ROT13 cipher algorithm to quickly encode and decode text for privacy, spoiler protection, and simple text obfuscation. This free ROT13 encoder/decoder shifts each letter 13 positions in the alphabet, creating scrambled text that's easy to reverse but not immediately readable. Perfect for hiding spoilers in movie reviews, obscuring answers in puzzles and riddles, protecting sensitive information in forums, or adding a simple layer of privacy to text content. The same transformation works both ways—encoding scrambled text again decodes it back to the original.

ROT13 (Rotate by 13 places) is a classic letter substitution cipher that has been used since ancient Roman times and remains popular today for non-critical text obfuscation. While not suitable for serious encryption, ROT13 is perfect for casual text hiding, preventing accidental spoiler reading, creating simple puzzles, or obscuring text in public forums where you want to hide content behind a "click to reveal" pattern. Our ROT13 tool makes encoding and decoding instant—just paste your text and copy the scrambled result.

Toolvado's text scrambler works entirely in your browser with complete privacy—no text is uploaded or stored on external servers. The ROT13 cipher tool processes text instantly while preserving spaces, punctuation, and numbers. Whether you need to encode spoilers, create simple encrypted messages, obscure answers in educational content, or experiment with basic cryptography, our free text scrambler provides instant results. ROT13 is reversible by applying the same transformation twice, making it easy to both hide and reveal text. Try our ROT13 encoder now and scramble your text instantly!
