Binary / Hex / Text Converter

Converting Text, Binary, and Hexadecimal

Computers store and transmit everything as bytes—numbers from 0 to 255. Text is just a human-friendly view of those bytes, created using a character encoding such as UTF-8. Binary and hexadecimal are two common ways to display the exact same byte data: binary shows each bit (0 or 1), while hex is a compact shorthand that is easier to read in logs, debuggers, and file headers.

This converter lets you move between these representations instantly. Type into any box and the other two update automatically. It’s useful for understanding encodings, inspecting protocol payloads, analyzing file signatures (magic bytes), and troubleshooting “garbled text” caused by encoding mismatches.

You can also switch the encoding in the settings panel. UTF-8 is recommended for modern Unicode text, ASCII is limited to basic English characters, and ISO-8859-1 (Latin-1) is a legacy single-byte encoding sometimes used in older systems.
