Top Hex Editors for Linux

In this article, we are going to review some of the best hex editors for Linux. But before we start, let’s look at what a hex editor really is.

What is Hex editor

In simple words, a hex editor allows you to examine and edit binary files. The difference between a regular text editor and the hex editor is that the regular editor represents the logical content of the file, while a hex editor represents the physical contents of the file.

Who use Hex editor

Hex editors are used for editing individual bytes of data and are mostly used by programmers or system administrators. Some of the most commonly used cases are debugging or reverse engineering binary communication protocols. Of course, there are many other things you can use hex editors – for example reviewing files with the unknown file format, performs hex comparison, reviewing program memory dump, and others.

Most of these mentioned hex editors are available to install from the default repository using your distribution’s package manager, like so:

# yum install package       [On CentOS]
# dnf install package       [On Fedora]
# apt install package       [On Debian/Ubuntu]
# zypper install package    [On OpenSuse]
# pacman -Ss package        [on Arch Linux]

If no package available, head over to the website of each tool where you will get the standalone package for download and installation procedures, along with details on dependencies.

1. Xxd Hex Editor

Most (if not every) Linux distributions come with an editor that allows you to perform hexadecimal and binary manipulation. One of those tools is the command-line tool – xxd, which is most commonly used to make a hex dump of a given file or standard input. It can also convert a hex dump back to its original binary form.

3. Hexyl Hex Editor

Another useful tool for examining binary file is hexyl, is a simple hex viewer for Linux terminal that uses a colored output to determine different categories of bytes.

The view of hexyl is split into three columns:

  • Offset column to tell you how many bytes into the file you are.
  • Hex column, which contains the hexadecimal view of the file. (Note that there is a splitting line in between)
  • Textual representation of a file.

The installation of this hex viewer is different for different operating systems, so it is recommended to check the readme file in the project to see the exact installation instructions for your OS.

4. Ghex – GNOME Hex Editor

Ghex is a graphical hex editor that lets users edit a binary file in both hex and ASCII format. It has a multilevel undo and redo mechanism that some may find useful. Another useful feature is finding and replacing functions and converting between binary, octal, decimal, and hexadecimal values.

whHexEditor is aimed mainly at large files. It works faster with larger files because it does not attempt to copy the entire file into your RAM.

  1. wxHexEditor looks like an excellent alternative to Okteta (which is great, if relatively simple) – but the domain name and wiki etc are no longer active, and their SourceForge project page is a mess. Pity.

  2. Surprisingly there is no decent hex editor for Linux. I tried all on this list and I’m disappointed.

    Better to run HxD under Wine.

  3. I don’t recommend using bless. It is unstable and can’t do simple read/save operations when you delete some bytes in between (probably because it is written in Mono). Use Ghex instead.

  4. Okteta is more than “another simple editor for reviewing raw data files”. I almost overlooked it. It is a native KDE app (hence the “k“) and blows away all the others, (at least if you use KDE).

    Runner up *would* be Bless, but it been regularly crashing on me for a couple of years now, so I would pick Ghex 2nd. Its also typical of the gnome vs KDE world if you compare Oketa with Ghex and see how often Gnome and many GTK apps are just too bare. Simplicity can be nice but Gnome goes too far. Of course, good old’ xxd is there but that isn’t sufficient as a full hex editor.

  5. Hexer in the screenshot is not the hexer this post is describing. And the URL is also wrong. Both URL and screenshot are for the C#-based GUI program, while the description is about C-based console one.

  6. Emacs is by far the best hex editor on the planet since you get a full featured editor too. Easily switch modes to find funky characters and edit in hex then switch back to ASCII for example.
