What is Binary Encoding?

Binary encoding converts text characters into their binary (base-2) representation using 0s and 1s. This is how computers internally store and process all text data.

Character Encodings

  • ✓ UTF-8: Universal encoding (1-4 bytes per character)
  • ✓ ASCII: 7-bit encoding (0-127 characters)
  • ✓ Latin-1: 8-bit encoding (0-255 characters)
  • ✓ UTF-16: 16-bit encoding (2 bytes per character)

Binary Formats

  • ✓ Spaced: 01001000 01100101
  • ✓ Grouped 4: 0100 1000 0110 0101
  • ✓ Continuous: 0100100001100101
  • ✓ New Lines: Each byte on new line

How Binary Encoding Works

  • ✓ Each character is converted to its numeric code point value
  • ✓ Each numeric value is converted to 8-bit binary (a byte)
  • ✓ Binary bytes are formatted according to selected style
