Two states. One alphabet for machines. Type a message and watch it turn into bytes.

The power of two choices

0 / 1
Hardware can reliably detect two distinct states. That becomes a bit. Stack bits and you get numbers. Use numbers as codes and suddenly you can store letters, images, anything.

What rule is running it?

Text to binary

Bytes you can copy
One common rule is ASCII: each character becomes a number, then that number is written in 8-bit binary. Type a whole message and you will get the full byte string.
Main tool
Type multiple letters
Message letters, spaces, punctuation
Characters 0 Bytes 0
Tip: this uses 8-bit bytes (0–255). For basic English, ASCII matches nicely. For emoji or many non-English characters, a wider encoding like UTF-8 is used in real systems.
Output
Binary string
Format 8-bit groups separated by spaces
Binary ready to copy
Decimal bytes same data, different base
