UEFITool is a free, open-source utility for examining and manipulating firmware images that conform to UEFI Platform Initialization specifications. It provides a graphical interface for exploring the internal structure of firmware used by computers and other electronic devices. The application parses firmware images into hierarchical trees containing volumes, files, sections, and related components. Users can inspect these elements and examine firmware organization without manually interpreting raw binary data. Its parsing engine performs structural and integrity checks to identify potential problems. UEFITool supports firmware research, reverse engineering, diagnostics, and analysis of low-level system components. The project includes editing capabilities in its established branches, while newer development versions continue to expand firmware parsing support.
