Introduction of Tool:

The Hex Editor is a web-based tool designed to facilitate the viewing and editing of binary files in hexadecimal format. It allows users to open binary files, display their contents in hexadecimal format, make modifications directly in the hexadecimal view, and save the changes back to the file. This tool is particularly useful for developers, system administrators, and anyone who needs to inspect or edit binary data.

  2. View Hexadecimal Content: Once the file is selected, its contents will be displayed in hexadecimal format in the textarea. Each byte is represented by two hexadecimal characters, separated by a space.
  3. Edit Hexadecimal Content: You can directly edit the hexadecimal content in the textarea. Ensure that you maintain the proper format (two characters per byte separated by a space).
