XPEViewer
PE file viewer/editor for Windows, Linux and MacOS
...The application combines PE parsing with tools for examining binary data, disassembly, symbols, regions, entropy, and memory layout. Integrated hexadecimal viewing and editing provide direct access to raw file contents. The project also incorporates signature scanning, extraction, unpacking, and related analysis components from the developer's wider tool ecosystem. Builds are available for Windows, Linux, and macOS despite the analyzed format being primarily associated with Windows. Its modular Qt-based codebase supports both continued development and specialized binary-analysis workflows.
