Binary Translator

Paste anything into the first field. With “Detect”, the translator looks at what you pasted: zeros and ones become text, any other text becomes binary code, and the line under the result says which way it went. You can also choose “Text to binary” or “Binary to text” yourself, and “Swap” puts the result into the first field to translate it back. In binary code every byte is written as eight digits, so the word Hi is 01001000 01101001. In UTF-8, the default encoding, letters with accents, Cyrillic, Chinese and emoji take two to four bytes, and the translator handles them both ways.

For text to binary, choose what goes between the bytes in the “Separator” list: a space, a new line, a comma or nothing. For binary to text, the bytes can be separated in any of these ways or not at all. The “Encoding” list has 21 encodings, from ASCII and UTF-16 to the Windows code pages, KOI8-R, Shift_JIS, GB18030, Big5 and EUC-KR, and “Unicode code points”, where each group of digits is the number of one character. Characters that an encoding cannot write become question marks and are listed under the result. “Open a file” translates a text file or turns any file of up to 1 MB into its bytes, and nothing is uploaded.
