ImHex
What it is
ImHex is a free hex editor for reverse engineers and programmers, available for Linux, macOS, and Windows. Its hex view supports searching and byte patching, with patch management and undo and redo. A custom C-like Pattern Language lets users describe structures and data types so file contents can be parsed and highlighted. 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 with rules, highlights matches, and lets users jump to them. An in-app Content Store provides community patterns, libraries, data processor nodes, encodings, themes, and YARA rules; developers can also build plugins with libimhex, the ImHex API, and the Content Registry. Most of ImHex is GPLv2-only, while libimhex and the UI plugin library are LGPLv2.1. It generally requires a GPU supporting OpenGL 3.0; slower software-rendered releases are available. macOS release binaries require macOS 15 or later, while older systems require building from source.
