Is the conversion based on bytes or characters?

It encodes text to UTF-8 bytes first, so each group represents one byte. This handles emoji and non-ASCII characters correctly, where a single character may span multiple bytes.

What format should I paste for decoding?

Space-separated values in the chosen base — for example "01001000 01101001" for binary or "48 69" for hex. Commas are also tolerated.
