Pattern Language

The custom C-like Pattern Language developed and used by ImHex is easy to read, understand and learn. A guide with all features of the language can be found on the docs page.


For format patterns, libraries, magic and constant files, check out the ImHex-Patterns repository.

Feel free to PR your own files there as well!


To use ImHex, the following minimal system requirements need to be met:

  • OS: Windows 7 or higher, macOS 10.15 (Catalina) or higher, "Modern" Linux (Ubuntu 22.04, Fedora Stable/Rawhide, and Arch Linux have official packages, other distributions can use the AppImage)
  • CPU: x86_64 (64 Bit)
  • GPU: OpenGL 3.0 or higher (preferable a dedicated GPU and not Intel HD Graphics)
  • RAM: 512MB, more may be required for more complicated analysis
  • Storage: 100MB

Plugin development

To develop plugins for ImHex, use one of the following two templates projects to get started. You then have access to the entirety of libimhex as well as the ImHex API and the Content Registry to interact with ImHex or to add new content.


The following OSs have packages available in their repositories making it easy to install ImHex.

Fedora (36+)

dnf install imhex

RHEL 9 / AlmaLinux 9 (coming soon)

Arch Linux (AUR)

yay -S imhex-bin

Third Party Repositories

ImHex is available in various thid party repositores.

Packaging status

Nightly builds

Nightlies are available via GitHub Actions here.


To compile ImHex on any platform, GCC (or Clang) is required with a version that supports C++23 or higher. On macOS, Clang is also required to compile some ObjC code. All releases are being built using latest available GCC.

Many dependencies are bundled into the repository using submodules so make sure to clone it using the --recurse-submodules option. All dependencies that aren't bundled, can be installed using the dependency installer scripts found in the /dist folder.
