UEFITool review
A cross-platform toolkit for parsing, verifying, searching and extracting UEFI firmware images.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
UEFITool is an open-source desktop application for viewing and analyzing UEFI-compatible firmware images. Its parser organizes image contents as a tree, while a graphical interface supports inspection and manipulation of elements. It is suited to firmware analysts and developers who need to understand image structure across Windows, macOS and Linux. The project also provides UEFIExtract and UEFIFind, extending the workflow from inspection to file extraction and pattern searches.
The surrounding utilities are a key part of its scope. UEFIExtract recursively dumps parsed structures to the filesystem, and UEFIFind searches image elements for specified patterns. Within the GUI, selected items can be hashed using hash, hash-body or hash-uncompressed actions; a built-in database of known UEFI-related GUIDs can also help identify elements. The project includes pre-built binaries and build instructions using Qt and CMake. This combination makes UEFITool a focused static-analysis toolkit rather than a general reverse-engineering suite: its listed capabilities cover parsing, integrity checks, search and extraction, not decompilation.
The main constraint is that image reconstruction and editing in the current engine remain incomplete. Although the interface includes element manipulation, the project notes that editing is possible only through the outdated 0.28 old_engine branch. That makes UEFITool a stronger fit for inspection and analysis than for modifying firmware images. It is a sensible choice for users who want a free, open-source toolchain for examining UEFI structure on desktop systems; those whose central requirement is dependable image editing should look for an alternative. Community support is the listed support channel.
UEFITool pros and cons
- Where it wins
- Parses UEFI-compatible images into a browsable tree and verifies integrity
- UEFIExtract dumps parsed structures; UEFIFind searches for specified patterns
- Provides item hashing and a built-in database of UEFI-related GUIDs
- Where it doesn't
- Image reconstruction and editing are incomplete in the current engine
- Editing is limited to the outdated 0.28 old_engine branch
- Focused on static firmware analysis rather than decompilation
