Frequently asked questions
How do I convert binary to text?
Paste the binary code (0s and 1s in groups of 8) and the text appears at once. Spaces and line breaks are ignored, so 01001000 01101001 and 0100100001101001 both give “Hi”. To go the other way, type text and copy the binary.
How is text turned into binary?
Each character is encoded as UTF-8 and each byte is written as 8 bits. Plain English letters use one byte; letters like ç use two and emoji use four.
Why does it say the binary is not valid UTF-8 text?
Some byte sequences are not text, for example a single 11111111. Check that no bits are missing or extra.
