A binary editor, also known as a hex editor or a disk editor, is a type of computer program that allows a user to view and modify the raw data of a file. Unlike a text editor, which interprets data as characters and displays them accordingly, a binary editor displays the underlying bytes of a file, typically in hexadecimal format. This raw representation is crucial for understanding and manipulating data that is not intended to be human-readable, such as executable programs, image files, or compressed archives.

Binary editors are essential tools for a variety of tasks. Programmers use them to examine and debug executable files, understanding how machine code is structured. Reverse engineers rely on them to analyze software behavior and identify vulnerabilities. Data recovery specialists may use binary editors to attempt to reconstruct damaged files by manually inspecting and correcting corrupted bytes. System administrators can employ them to modify configuration files that may not have dedicated editing tools, or to inspect low-level system data.

The interface of a binary editor usually presents data in two main panes. One pane shows the hexadecimal representation of the bytes, with each byte typically displayed as two hexadecimal digits (00-FF). The other pane often provides an ASCII or extended ASCII interpretation of these bytes, showing printable characters where they exist. Users can navigate through the file byte by byte and make direct modifications to the hexadecimal values. It is important to note that indiscriminate editing of binary files can easily corrupt them, making proper understanding of file formats and data structures essential.
