Why 8 bits per character?

A byte is 8 bits, and classic ASCII fits every English letter, digit, and symbol in one byte.

Can I decode binary without spaces?

Add a space between each 8-bit byte so the decoder knows where each character starts.

Emoji have code points above 255, so they use more than 8 bits — the decimal view shows the full code point.

Each character becomes its 8-bit binary char code. Characters above U+00FF use their full code point.

How to use Binary Translator

01Type in the Text box to see the binary, or paste space-separated bytes in the Binary box to decode.
02Each character becomes one 8-bit byte.
03Use the Hexadecimal and Decimal rows for other common encodings.

About Binary Translator

Computers store every character as a number, and binary is those numbers written in base 2. The letter A, for example, is 65 in decimal and 01000001 in 8-bit binary.

This tool uses each character's Unicode code point, which matches ASCII for plain English text.
