# Hex Editor A **Hex editor** is a special type of editor that can open any type of file and display its contents, byte by byte. You can see these invisible characters (and regular characters, too) with a hex editor, where they appear as hexadecimal values. ‌ You can use Exploit Pack's hex editor to quickly view and edit binary files. **Go to File -> Open** and select the desired file to be used by the editor: ![](/files/-MUDO7QCpnOHsX8MOCrZ) After that the file will be loaded into the Editor as shown below: ![](/files/-MUDOCgfNIXWTjNINJ_A) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
