UEFITool is a cross-platform C++/Qt application that parses UEFI-compatible firmware images into a tree structure, verifies their integrity, and provides a GUI to view and edit their elements. It supports UEFI PI Specification images across x86, x86-64, arm64, and RISC-V systems.
Use cases
- view the contents of a UEFI BIOS firmware image
- edit or replace modules inside a UEFI firmware volume
- extract firmware files from a motherboard BIOS dump
- inspect FFSv3 volumes and firmware structure
- patch firmware images to add or modify options
- reverse engineer UEFI firmware images
When to choose
- you need a cross-platform GUI to inspect or modify UEFI firmware images
- you want an open-source alternative to vendor BIOS tools
- you need to parse modern UEFI features like FFSv3 volumes
- you want to extract or search firmware contents via derived tools like UEFIExtract or UEFIFind
When to avoid
- you only need official EDK2 tooling without IBV customization support (consider FMMT)
- you need a scriptable command-line-only workflow (the new engine's console UI is still in development)
- you need to modify non-UEFI legacy BIOS images
