Text to binary translator

Text to binary is a free tool that runs entirely in your browser, with no data ever sent to a server. Convert text to 0s and 1s, or the other way round.

How it works

Each character is first converted into one or more bytes according to UTF-8 encoding, then each byte is written in base 2 over 8 digits : the "H" in "Hello" becomes 01001000. Bytes are separated by a space.

What this tool does not do

This tool only applies the transformation described above, with no spelling correction and no understanding of the text's meaning. A text of tens of thousands of lines is processed instantly ; beyond that, the only limit is your device's memory.

Frequently asked questions

Why does an accented character produce several groups of 8 digits?

In UTF-8, characters outside the basic ASCII range (like "é") are represented by two or more bytes, each 8 bits long.

Is my data sent to a server?

No : the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?

No : the tool works directly on this page, with no sign-up and no install.
