What does Text to Binary Converter do?

Turn text into binary using UTF-8 encoding, with a choice of separator and grouping. Each byte is shown as eight bits, so multi-byte characters such as emoji expand to several groups — which is exactly how a computer stores them.

Frequently Asked Questions

How is text converted to binary?

The text is encoded to bytes using UTF-8, then each byte is written as eight binary digits. "A" is byte 65, which is 01000001.

Why do some characters produce more than eight bits?

Because UTF-8 is variable length. ASCII characters take one byte, most accented and Greek letters take two, most CJK characters three, and emoji four. Each byte becomes its own group of eight bits.

Is this the same as ASCII binary?

For plain English text, yes — UTF-8 is byte-identical to ASCII for the first 128 characters. It differs as soon as any character outside that range appears.
