Turn text into binary code and decode binary back into text. Fast, free, and fully private.

Encode turns every character into its 8-bit binary code, separated by spaces. Decode reads groups of 8 binary digits and turns them back into text. It handles spacing and line breaks in the input automatically.
Hi becomes 01001000 01101001. Paste that back in and click Decode to get Hi again.
