8-Bit Binary, Decimal & Hex Table (256 Values)

Look up all 256 byte values in binary, hexadecimal, and decimal. Character mappings use Windows-1252, with values 0–127 matching standard ASCII.

About This Reference Table

Each row represents one 8-bit byte, ranging from decimal 0 to 255. The binary column shows eight bits, and the hexadecimal column shows the same value in base 16.

Decimal 0–127: Standard ASCII values.
Decimal 128–255: Windows-1252 byte mappings, including five undefined values.
Undefined values: Five byte values have no assigned character in Windows-1252.
Control characters: Non-printing values are displayed using readable names.

Other encodings, such as UTF-8 and ISO-8859-1, may interpret the same byte values differently.
