HexEdit

HexEdit is a small-sized, portable and free hex editor that features straightforward options for directly examining files via hexadecimal display, regardless of their format, as well as for making modifications. It can be easily used.

The entire program is wrapped in a single executable file that can be copied to the local or removable disk, in order to seamlessly launch the application on any computer without previous installers. It doesn't change Windows registry settings, need any DLLs to run, or create additional files on the computer without your permission. To remove it, just delete the .exe.

At startup, you're greeted by a file browser that you can use to navigate Explorer directories and open a file. The main app window has a standard look with white text on a black background, showing the hex code of the file.

It's possible to scroll to any position within the code, toggle between hex and octal display mode by opening the right-click menu, select an offset to edit by simply typing a new value, copy values to the Clipboard, cut and paste data, insert new characters, as well as use a basic search tool to quickly track down hex, octal or ASCII characters.

HexEdit enables you to customize colors for the active and inactive cursor, selection, text and background, together with font settings, such as type, style, size and script. The modified file can overwrite the original or it can be saved as a new one.

HexEdit comes packed with easy-to-use and effective options for editing hex code. Unsurprisingly, it had minimal impact on the PC's performance in our tests, running on low CPU and RAM. Although it hasn't been updated for a long time, it still works smoothly on newer Windows. Command lines are supported for advanced PC users.
