What is Text ↔ binary converter?
Shows exactly how text is represented at the byte level in binary, octal, or hexadecimal — each character becomes one byte's worth of digits, which is how text actually looks inside a computer's memory.
How to use it
Type text to see its byte representation in the chosen base, or paste space-separated byte values to decode them back into text.
Example
"Hi!" in binary -> 01001000 01101001 00100001
