Just like EXIF data hides info inside photos — now you can embed secret messages inside a single emoji.
Copy the emoji anywhere. Only this page (or anyone with the decoder) can reveal the hidden text.
100% static HTML • No server • Works offline • Uses zero-width Unicode steganography
Just like EXIF metadata in images, but for emojis. Copy the emoji anywhere — the message travels with it.

Your text is converted to binary
Using the browser’s TextEncoder, every character becomes 8 bits.
Binary is turned into invisible characters
0 becomes U+200B (zero-width space)
1 becomes U+200C (zero-width non-joiner)
These invisible characters are appended to your chosen emoji
The result still renders as a normal emoji, but the hidden payload travels with it when you copy/paste.
Decoding scans only the trailing invisible characters
This makes it safe even if your emoji uses complex sequences internally.
