Binary to Text decodes 0s and 1s into readable text. Paste bytes separated by spaces, commas or new lines, or one long string, which is split into 8-bit groups. The bytes are read as UTF-8, so emoji and non-English letters decode correctly.
It also decodes hexadecimal, decimal and octal bytes. If the input isn’t valid, it tells you exactly why. To go the other way, use the Text to Binary converter.

Frequently asked questions
What does 01001000 01101001 mean?
It decodes to “Hi”: 01001000 is 72 (H) and 01101001 is 105 (i).
Why do I get an error?
Binary can only contain 0 and 1, each group can be at most 8 bits, and a continuous string must be a multiple of 8 bits long. The message shows which rule failed.
Does it support Unicode?
Yes. Multi-byte UTF-8 sequences, including emoji and other scripts, decode correctly.
