About this tool

Convert text to 8-bit binary and back with full UTF-8 support, all in your browser.

How is non-ASCII text handled?

Text is encoded as UTF-8 first, so each character becomes one or more 8-bit bytes that round-trip correctly.

What format does the binary use?

Each byte is shown as 8 binary digits separated by spaces, which is also the format expected when decoding.
