An online text steganography tool that hides secret information inside ordinary text using zero-width characters, letter-case encoding, acrostic first-letter encoding and more, with optional passphrase encryption. Paste to embed or extract; processed purely in your browser, nothing is uploaded to the server.
Everything runs locally in your browser and is never uploaded to a server. Zero-width mode writes the information into invisible characters, invisible to the naked eye; case mode relies on the letter case of an English carrier; acrostic mode takes the first character of each line. For learning and everyday use only.
