The Science of Zero-Width Binary Interleaving

This utility encodes your secret payload into binary bits (0s and 1s). It maps each bit to non-printing Unicode characters: Zero-Width Space (U+200B) for 0, and Zero-Width Non-Joiner (U+200C) for 1. These characters are inserted invisibly between the words of an ordinary cover sentence.

Zero Typographical Distortion

Because zero-width characters render with exactly zero horizontal pixel width, the visible sentence appears completely normal on computer screens, tablets, and smartphones.
