IconVault's Text to Binary converter translates text into binary and decodes binary back to text in both directions. It is UTF-8 aware, so emoji and non-English characters encode correctly, and you can choose the delimiter between bytes (spaces, commas, none and more) to match whatever format you need.

Binary input is validated with clear errors: the tool tells you if characters are not 0 or 1, if the length is not a multiple of 8, or if the bytes are not valid UTF-8. It is free and runs fully in your browser, which makes it handy for CS homework, encoding puzzles and learning how text is stored as bits.
