Text ↔ Binary, Both Ways
Type in either box and the other updates instantly. Text encodes to UTF-8 bytes first, then each byte becomes an 8-bit binary group separated by spaces — this means non-English characters (like é or 中) correctly round-trip as multiple bytes, not one.
Frequently Asked Questions
Why does one character sometimes produce more than 8 bits?
Text is encoded as UTF-8 first. ASCII characters take 1 byte (8 bits), but accented letters, Turkish characters and emoji can take 2-4 bytes — each byte shows as its own 8-bit group.
What if my binary input has invalid groups?
Groups must be exactly 8 characters of 0s and 1s, space-separated. Invalid or incomplete groups are skipped rather than crashing the conversion.
