Summary

ImHex is a free hex editor for reverse engineers and programmers, available on Linux, macOS, and Windows. Its hex view supports searching, byte patching, patch management, and undo and redo. A custom C-like Pattern Language lets users define structures and data types to parse and highlight file contents. Analysis tools include data inspection, file type parsing, byte type and entropy graphs, and detection of encrypted or compressed files. The YARA view scans files against rules, highlights matches, and provides navigation to them. An in-app Content Store offers community patterns, libraries, processor nodes, encodings, themes, and YARA rules; developers can also build plugins using libimhex, the ImHex API, and the Content Registry. Most of ImHex uses the GPLv2-only license, while libimhex and the UI plugin library use LGPLv2.1. ImHex generally needs a GPU supporting OpenGL 3.0, though slower software-rendered releases are available. Release binaries for macOS require macOS 15 or later; older versions require compiling from source.

Who it is for

ImHex suits programmers and reverse engineers who need to inspect or edit binary data, apply patterns, or scan with YARA rules. Users should check its GPU and macOS version requirements before choosing it.

What is good

  • Pattern Language parses and highlights defined structures.
  • Includes byte patching, patch management, and undo and redo.
  • YARA view highlights matches and enables navigation.
  • Community content and plugin development are supported.

What to know first

  • Generally requires a GPU with OpenGL 3.0 support.
  • macOS release binaries require macOS 15 or higher.

Verdict

ImHex combines hex editing with structured parsing, file analysis, and YARA scanning. Its platform requirements and macOS release limitation are worth checking before installation.
