About this tool

Computers store every character as binary, and this converter makes that visible. It turns text into space-separated 8-bit groups and decodes binary back into readable text, handling full UTF-8 so symbols and accented letters work too.

It’s handy for learning how text encoding works, for puzzles, or for encoding a short message. The decoder is forgiving about spacing and tells you when the input isn’t valid binary. Everything runs in your browser.

Frequently asked questions

What encoding is used?

UTF-8. Each character becomes one or more 8-bit bytes, so accented letters and symbols convert correctly, not just plain ASCII.

How should I format binary to decode?

As groups of eight 0s and 1s separated by spaces, like 01001000 01101001 — exactly the format this tool outputs.
