Here are 5 free open source hex editor software for Windows. These hex editor software allow you to edit any binary file in an easy way. You can open any executable or a library file in these software and edit the contents in the form of hex. These software offer some basic and some power tools to edit a hex file and save the changes. You can use these software as you use the text editors. These software support most of the common editing tools like cut, copy, paste, undo-redo, find-replace, selecting specific sequence, measure the size of hex values and some more. All the software that I have listed below are open source and their source code is publicly available to download. You can fork the code and if you have relevant knowledge, then you can further extend the functionality of these software.

Editing the hex code can’t be done in normal ways. If you try to open any EXE, DLL, or any other binary file in a text editor, then you will see data which is in un-understandable form. And that is why to edit hex data you need some special text editors which can read the hex code perfectly and you can edit that. There are some hex viewer tools available, but they can’t edit hex files. And in the following list, I will talk about 5 such software that can do that and you will like them.
