ImHex
ImHex is a native hex editor for macOS that helps developers and reverse engineers inspect, analyze, and edit binary data.
What is ImHex?
ImHex is a hex editor for working with binary files, firmware images, save data, and other low-level data formats on macOS and other major platforms. It is designed for developers, reverse engineers, security researchers, and technical users who need more than a basic byte viewer. The app combines traditional hex editing with structure-aware analysis tools, making it easier to understand unknown file layouts and inspect encoded data. Users can define binary formats with its pattern language, visualize content through specialized analysis views, and disassemble supported instruction sets directly inside the app. ImHex also supports plugins and command-line workflows, which makes it useful both for interactive inspection and for repeatable development or testing tasks. It is published by WerWolv and distributed as a standalone desktop app.
Key features
- Open and edit binary files in a structured hex view
- Describe file layouts with a pattern language and inspect decoded fields
- Analyze raw data with entropy, byte-type, and inspector tools
- Disassemble supported machine code and bytecode formats
- Visualize embedded content such as images, audio, or 3D data when supported
- Extend the editor with plugins for custom workflows
- Use command-line options for automation and testing tasks

Safety overview
Status: Safe
ImHex is legitimate desktop software for inspecting and editing binary data. It will read any files you choose to open, so the main practical risk is changing or saving over important data by mistake when working with firmware, executables, disk images, or other sensitive files. Using copies of critical files and keeping backups before editing is a sensible precaution.
Recommendation: Keep ImHex if you use it for reverse engineering, binary inspection, firmware analysis, or other low-level file work. If you no longer need those workflows, you can remove the app like other standalone Mac software without affecting macOS itself.
