How to edit hex</a>

Hex-editor is used to edit data represented in hexadecimal (hexadecimal) codes.

Most often with the help of such applications changes are made to files created with the help of any programming languages, and then compiled.

For example, in executable files (extension exe, ex4, etc.), in the files of the connected resources (dll, res, etc.), image files of disks (iso, mds, etc.).



Use the built-in editorHexadecimal codes, which is in most applications designed to develop or edit software products in compiled languages. For example, such an editor should be part of an integrated development environment, a debugger program, or a disassembler.


Choose online applicationFor editing hexadecimal codes, if you do not plan to engage in programming permanently. In this case, it makes no sense to install powerful development tools with a built-in hex editor. In the network, you can find a sufficient number of programs of this kind, both in the paid version, and free. For example, it could be the Cygnus Hex Editor application. This is an editor with a very simple interface and also does not require installation - it is ready to work immediately after downloading to your computer. A free version is available on the developer's website, a direct download link - http://softcircuits.com/dl/apps/cygnusfe.zip.


Press ctrl + o after loadingAnd running the hex editor - so you will open the file open dialog. Locate the file whose code you want to edit, and click the Open button. In the left part of the application window there will be a table representing the bytes of information stored in the file in hexadecimal codes, and the corresponding ASCII character codes will be placed on the right side. You can edit both HEX and ASCII, and the changes you make will be reflected in both tables simultaneously. To save all changes in the source file, press ctrl + s.
