How do I convert text to its 8-bit binary representation?

Short answer

Paste your text into a browser-based text-to-binary converter and it turns each character into its 8-bit binary byte, with a space between bytes for readability. The conversion runs on your device and nothing is uploaded.

Every character is a byte

Text is stored as numbers, and in common encodings each basic character maps to a value that fits in 8 bits, one byte. Converting text to binary shows those bytes directly, which is handy for learning how encoding works, for puzzles, or for inspecting a short string bit by bit. A converter turns each character into its 8-bit pattern so you do not have to look up code points by hand.

Readable byte-by-byte output, done locally

A client-side converter processes the text in your browser and separates each byte with a space, so the binary is easy to read and line up with the original characters. Because it runs locally, the text you paste is never sent to a server. It is free and needs no sign-up.

Step by step

  1. Open the converter. Open the text to binary converter in your browser.
  2. Paste your text. Paste the text you want to see in binary.
  3. Read the binary. Read the 8-bit binary output, one spaced byte per character.

Frequently asked questions

How many bits per character?

Each basic character is shown as one 8-bit byte.

Why are there spaces in the output?

A space is placed between each byte so the binary is easier to read.

Is my text uploaded?

No. The conversion runs in your browser, so nothing is sent anywhere.
