String to Binary Converter
Encode text strings into binary 0s and 1s with configurable separators.
How to use it
- Enter any string to get binary code.
Examples
| Code | 01000011 01101111 01100100 01100101 |
Every character has a numeric code point behind it — 'C' is 67, 'o' is 111, and so on for ASCII text. This tool converts each character in the string to its numeric value, then writes that value out as an 8-bit binary byte, joined with spaces so each character's byte is easy to pick out.
