Text to binary

Convert text to its binary (0s and 1s) representation, byte by byte.

About this tool

Each character becomes its 8-bit character code in binary, space-separated — the form computers actually store. Characters beyond the basic set use their Unicode code point’s binary value.

Common questions

Which encoding does this use? The character code of each character (Latin-1 range gives exact byte values for English text).

How do I turn it back? Use the Binary to Text converter with the same space-separated format.
