Text is encoded as UTF-8, so letters outside basic ASCII (é, €, emoji) use 2 to 4 bytes each. Code points list one number per character instead.

About this tool

How to use Text to Binary

  1. Type text, or switch to “Codes → text” and paste codes.
  2. Choose the format and separator.
  3. Copy the result.
