Worked example
Converting a two-letter word
Input: "Hi". H is byte 72 and i is byte 105, so the binary result is: 01001000 01101001. Paste that binary into the reverse direction and you get "Hi" back.
- Binary input must be 8-bit groups separated by spaces (a single unbroken run whose length is a multiple of 8 also works).
- Characters outside plain ASCII take two to four bytes in UTF-8, so one visible character can produce several binary groups.
- Invalid byte sequences are reported as an error instead of being replaced with placeholder characters.
Most emoji are four bytes in UTF-8, and each byte becomes one 8-bit group, so a single emoji shows as four groups.
About this tool
The Text to Binary Converter turns text into the 8-bit binary form of its UTF-8 bytes, and converts binary back into text. Because it works on UTF-8 bytes, accented letters and emoji convert correctly instead of breaking the way single-byte converters do.
