Frequently Asked Questions
Each character is mapped to its ASCII (or Unicode) code point, then that number is represented in base 2 (binary). For example, 'A' has ASCII value 65, which in 8-bit binary is 01000001. This tool uses 8-bit (one byte) representation per character for standard ASCII, which covers characters 0–127.
Characters above ASCII 127 (accented letters, emoji, CJK characters) are multi-byte in UTF-8. This tool shows the decimal code point value. For full UTF-8 byte-level binary encoding, the output may differ from single-byte representations.
Hexadecimal (base 16) uses digits 0–9 and letters A–F. One hex digit represents exactly 4 bits, so one byte is always two hex digits (00–FF). It's the most compact human-readable form for raw binary data, widely used in programming, memory addresses, color codes (#FF5733) and cryptographic hashes.
