A hex editor is a computer program that allows users to edit the binary code, represented by hexadecimal values, which makes up a computer file. Using a hex editor you can view and edit the raw file data, making modifications down to the core programming of the software application.
Many free hex editors are available for download. Features range from simple to complex. While some provide only a raw look at the binary code, some provide a rich set of tools for interpreting and editing the data.
