Text to Binary

Convert text into binary, eight bits per character.

Quick Tool Overview

Text to Binary converts your text into ones and zeros, defaulting to the UTF-8 bytes that a file or a network packet genuinely contains — so a plain letter produces eight bits, an accented letter sixteen and an emoji thirty-two. A code point mode gives one value per character instead.

About the Text to Binary

Binary is how a computer actually holds your text: each character becomes a number, and each number becomes a run of ones and zeros. Converting to binary makes that visible, which is why it is the standard first exercise in any computing course.

The default is UTF-8 bytes, which is what a file on disk or a network packet genuinely contains — plain English characters produce eight bits each, while an accented letter produces sixteen and an emoji thirty-two. There is also a code-point mode, which gives one binary number per character regardless of how it would be stored. The difference between those two is the whole reason a string can be longer in bytes than in characters.

Key features of the Text to Binary

Real UTF-8 bytes

The default is what is actually stored, which is why an emoji is four bytes and a letter is one.

Code point mode

One binary value per character regardless of encoding, which is easier to follow when teaching.

Choice of grouping

Space-separated bytes for reading, or one solid bitstream when the format demands it.

Bit and byte counts

The size of the text in both units, which is what a storage or payload limit measures.

Reverses cleanly

The output decodes exactly with the Binary to Text tool, in either mode.

How to use the Text to Binary

  1. 1

    Type or paste your text

    A word, a sentence or a whole document.

  2. 2

    Choose bytes or code points

    UTF-8 bytes is what is really stored; code points give one value per character.

  3. 3

    Set the separator

    A space between bytes is standard and readable; no separator gives a solid bitstream.

  4. 4

    Copy the binary

    The result comes with a bit count, so you can see exactly how large the text is.

Frequently asked questions

Eight for any plain English character, because UTF-8 stores those in a single byte. An accented letter takes sixteen bits, most CJK characters twenty-four, and an emoji thirty-two.
