Frequently Asked Questions

Each character is converted to its Unicode code point (a number), then that number is expressed in the selected base. For ASCII characters (A=65, a=97, space=32), binary gives an 8-bit representation. For example 'A' = 65 decimal = 01000001 binary = 41 hex = 101 octal.

All three represent the same underlying numbers: Binary uses base-2 (0 and 1), Octal uses base-8 (0–7), Decimal uses base-10 (0–9), and Hexadecimal uses base-16 (0–9 and A–F). Hex is popular in computing because 2 hex digits exactly represent 1 byte (8 bits).

Yes. The tool uses JavaScript's codePointAt() which returns the full Unicode code point for any character, including emoji and non-ASCII text. When decoding, each encoded value is parsed back to a code point with String.fromCodePoint().
