Hidden Message reversible

Bury a secret inside ordinary-looking cover text using invisible zero-width characters. The result copies and pastes as normal text — the payload rides along unseen.

Conceal

Cover text (what people see) Secret to hide

Output — invisible payload included

Hidden payload: 0 bytes · invisible chars added: 0

Recovered secret

Homoglyph Swap reversible

Replace Latin letters with visually identical characters from other Unicode scripts (Cyrillic, Greek). Reads the same to a human, but is a different string to a computer — defeats naive text matching and filters.

Output

Tip: "Normalise" reverses the swap and applies Unicode NFKC folding — paste any suspicious lookalike text to clean it.

Glitch / Zalgo one-way

Stack combining diacritics onto each character for the corrupted "zalgo" look. Decorative — strip it back with the Classic tab's normalise.

Classic Ciphers reversible

The dependable workhorses: ROT-N / Caesar, Atbash, reverse, and Unicode-safe Base64. Encode and decode in one place.

Output

ROT-13 and Atbash are their own inverse — run the output through again to decode. Base64 round-trips full Unicode (emoji included).
