Text ↔ Binary Converter
UTF-8 preserves accented letters, CJK, emoji, whitespace and null bytes. Strict ASCII rejects characters or bytes outside 0–127. Binary accepts whitespace separators and rejects punctuation, incomplete bytes and invalid UTF-8.
How to use
Choose a direction and encoding, enter text or binary, then copy or download the live output. Choose spaces, no separator or newlines for binary output. Swap uses the valid output as input and reverses direction.
