What are some GUI applications that will let me view and edit binary files (executables, images, etc.).

  • GHex is a reasonable viewer, but it's a terrible editor. Selecting a range of bytes was really awkward. Haven't tried the others. Okteta from one of the other answers worked well for me. – Don Kirkby Jul 2 '15 at 20:52

If you're using KDE, Okteta is the way to go.

    +1: okteta seems much better than ghex, and the image posted it's helpful to gain proper usage in the many options available – CapelliC Apr 19 '14 at 17:43

    Okteta runs OK under Ubuntu 19.04 (GNOME). – FedonKadifeli Jul 7 '19 at 16:40

Try GHex

sudo apt-get install ghex

From the app's Github page:

GHex is a hex editor for the GNOME desktop.

GHex can load raw data from binary files and display them for editing in the traditional hex editor view. The display is split in two columns, with hexadecimal values in one column and the ASCII representation in the other. A useful tool for working with raw data.

sublime is a good choice and it is multi purpose editor.
