Hexadecimal editors allow you to open any type of file, regardless of its content, although they are mainly used to edit binary files to access their information and, where appropriate, edit, copy or delete it, with all that this entails. What is the best app? If we don’t know where to start, in this article we show you the hexadecimal editors in the form of an application and via the web.
Editing the hexadecimal code of a file was originally intended to edit certain values ​​to modify the behavior of an application. Although this is still their main use today, they are also widely used to modify game save files to modify their behavior.
The hexadecimal codes are a physical representation of the files. Computers store files in binary format, a series of bytes that have a value from 0 to 255. Each byte is assigned a specific address starting with 0.
Hex file editors show us the binary code of a file sorted into three columns: offset values, hex code display, and character values. With hex editor, we can edit, copy, paste and even print and save the changes.
Hexadecimal files can be stored in text or binary format. If it is a file in text format, we can use the Notepad application included natively in all versions of Windows. However, if it is a file in binary format, natively Windows does not offer us any application to be able to access and edit its content.
If you want to know which are the best applications and websites to open and edit hexadecimal code, we invite you to continue reading.
