What is a Hex Viewer?
A Hex Viewer (or Hex Editor) is a tool that allows you to view the raw data of a file. Computers store data as a series of 0s and 1s, which are grouped into 8-bit bytes. Hexadecimal (base 16) is a convenient way to represent these bytes.
Our Online Hex Viewer helps developers, reverse engineers, and curious users inspect the internal structure of any file. You can identify file types by their magic numbers, debug binary data, or simply see what's inside a file that text editors can't open.
