FAQ

Is this ASCII or UTF-8 binary?
Encoding uses UTF-8 bytes. For basic English letters that is the same as ASCII. Multi-byte characters such as é use more than one 8-bit group.
How should binary be formatted for decode?
Use groups of exactly 8 bits (0 and 1), separated by spaces. A continuous 01 stream is accepted only when its length is a multiple of 8.
What happens to invalid bits or invalid UTF-8?
Invalid groups or byte sequences are not invented. The tool reports them as unavailable and keeps the source instead of silently substituting replacement characters.
Does conversion run locally?
Yes. Encoding and decoding run in your browser.
