How are non-ASCII characters handled?

Text is encoded as UTF-8, so accented letters, symbols and emoji are turned into multiple bytes — each still shown as an 8-bit group.

Why is each byte 8 digits long?

A byte is 8 bits, so each byte is padded to 8 binary digits. This keeps the output aligned and easy to split back into bytes.

Is my text sent to a server?

No. The conversion runs entirely in your browser, so nothing you type is uploaded or stored.

Convert text into UTF-8 binary, 8 bits per byte.

Text to binary converter

Turn any text into its binary representation. Each character is encoded as UTF-8 bytes, and every byte is shown as 8 binary digits separated by spaces. ASCII characters become one byte each; accented letters, symbols and emoji span several bytes.

Everything runs in your browser — nothing you type is uploaded.
