How text becomes binary

Every character has a number in the Unicode/ASCII table — A is 65, a is 97, space is 32. The computer stores that number in binary using 8 bits (one byte): A = 01000001, a = 01100001. "Hi" is 01001000 01101001.

Hindi and emoji use UTF-8, which takes 2–4 bytes per character — this converter handles them too. For plain numbers use the binary, decimal, hex converter.

Frequently asked questions

What is 'hello' in binary?

How do I read binary back to text?

Split into groups of 8 bits, convert each to a decimal number and look it up in the ASCII table — or paste it in the binary box above.

Why 8 bits?

A byte is 8 bits, which holds numbers 0–255 — enough for all ASCII characters.
