A binary editor, also known as a hex editor, is a software tool that allows users to view and edit the raw binary data of files. Unlike standard text editors that display content in a human-readable format, binary editors show data in hexadecimal and ASCII formats. This enables users to manipulate file contents at a low level, which is useful for tasks like debugging, reverse engineering, or modifying executable files. Binary editors are commonly used by software developers, security researchers, and data recovery specialists. They can help identify file structures, locate specific data patterns, or recover lost information. Popular examples of binary editors include HxD, Hex Fiend, and 010 Editor.
