The hexdump Utility

The hexdump Utility


This is just a quick utility to see exactly what is in a binary file.

See the byte2hex utility to create a hex text file that can be edited and converted back to binary.

See the HexTools utility in GnuWin32 for a more feature-rich version.

If you don't want to install anything, try the online version of HexDump.


This is a command-line tool. If you don't know what this means, this probably isn't the right tool for you.

It just takes a list of files and dumps the contents in hex on stdout.

The format is <offset (in hex)>: <hex bytes> <ASCII values>. Only alphanumeric ASCII values are shown: everything else is shown as a period (.).

For example:

hexdump myfile1.dat

There are no options.
