How do I convert text to binary?

Type or paste any text in the input panel. Each character is encoded as its UTF-8 byte value in 8-bit binary groups separated by spaces. Click 'Copy Output' to copy the result.

Why does one character produce multiple binary groups?

Characters outside the basic ASCII range (such as emoji or accented letters) require multiple bytes in UTF-8, so they produce more than one 8-bit group. Each group represents one byte of the UTF-8 encoding.

Is the text to binary converter free?

Yes, completely free. The conversion runs entirely in your browser using the built-in TextEncoder API — no data is sent to any server, and no signup is required.
