String Obfuscator
Obfuscate and deobfuscate text using ROT13, ROT47, reverse, homoglyphs, zero-width characters, and Base64.
Frequently Asked Questions
What is string obfuscation?
String obfuscation transforms readable text into a less recognizable form. It is commonly used to hide spoilers, obscure email addresses from bots, or simply transform text for fun. It is not a secure encryption method.
What is ROT13 and ROT47?
ROT13 shifts each letter 13 positions in the alphabet (A→N, B→O, etc.). Applying it twice restores the original text. ROT47 extends this concept to ASCII characters 33–126, rotating by 47 positions, covering letters, digits, and symbols.
What are homoglyphs and zero-width characters?
Homoglyphs are Unicode characters that look visually similar to Latin letters (e.g., Cyrillic 'а' vs Latin 'a'). Zero-width characters are invisible Unicode characters inserted between letters. Both techniques make text appear normal but differ at the byte level.
