What is a Hex Viewer?

A hex viewer displays binary data in hexadecimal format, showing both the raw bytes and their ASCII representation. This is useful for analyzing file structures, debugging, and understanding binary data.

Common Use Cases

  • • Analyzing file headers and magic bytes
  • • Debugging binary data issues
  • • Reverse engineering file formats
  • • Forensic analysis of files
  • • Understanding binary protocols
  • • Data recovery and repair

File Type Detection

Files are identified by their "magic bytes" - the first few bytes that uniquely identify the file format. Common examples include JPEG (FF D8 FF), PNG (89 50 4E 47), and PDF (25 50 44 46).
