Understanding the Conversion Process
Each number you enter represents a Unicode code point — the unique numeric identifier for a character. The converter parses each number using your selected base, then maps it to the corresponding Unicode character using String.fromCodePoint().
For example, the hex values 48 65 6C 6C 6F decode to Hello. Emojis like 🌍 (code point U+1F30D) would be 1F30D in hexadecimal or 127757 in decimal.
