How text becomes binary.

Every character maps to a number, written in base–2 and padded to 8 bits. Here are common ones — the full set lives in the ASCII table.

Character	Decimal	Binary (8-bit)
A	65	01000001
H	72	01001000
e	101	01100101
l	108	01101100
o	111	01101111
a	97	01100001
0	48	00110000
[space]	32	00100000

FAQ

Text to binary, explained.

What's the difference between this and the full Binary Translator?

This page only goes one direction (text to binary). The full Binary Translator also decodes binary back to text, swaps direction, and lets you switch between ASCII and UTF-8 encoding.

Why is the binary longer for accented letters or emoji?

This tool encodes as UTF-8, where any character outside the basic 128 ASCII characters can take 2–4 bytes instead of 1. See the ASCII table for which characters stay at a single byte.

Can I convert the binary back to a decimal number afterward?

Yes — copy a single byte (8 digits) into the Binary to Decimal tool to see its base-10 value.
