Apktool vs ImHex

Apktool is a command-line tool for reverse engineering Android APK files. It can disassemble an app’s resources into a form close to their original structure, then rebuild an app after changes such as translation or permission edits. Its analysis mode attempts to extract resources and the manifest for inspection without rebuilding. Apktool runs on Windows, Linux, and macOS; its official installation guide describes wrapper-script steps for those systems and requires Java 8 or later. Decode options include choosing resource-resolution behavior, skipping resources or source disassembly, and setting a framework directory. Build options include selecting an aapt2 binary, adding a generic Network Security Configuration file, and disabling APK repacking. The Apache license permits redistribution, modification, and integration into another project. Apktool is free, with no pricing tiers stated. Its FAQ says Android devices are not officially supported, and some OEM-modified “Magic APKs” may not decode or build. Builds are unsigned; copying a signature retains only the original APK signature v1 scheme.

ImHex is a hex editor for reverse engineers and programmers, available for Linux, macOS, and Windows. Its Pattern Language uses C-like syntax to describe structures and data types, which ImHex can use to parse and highlight file contents. The hex view supports searching, byte patching, patch management, and undo and redo. Analysis features include data inspection, file type parsing, byte type and entropy graphs, and detection of encrypted or compressed files. A YARA view scans files with rules, highlights matches, and lets users jump to them. The in-app Content Store offers community patterns, libraries, processor nodes, encodings, themes, and YARA rules; developers can also build plugins with libimhex, the API, and Content Registry. ImHex is free. Most of the application is GPLv2-only, while libimhex and the UI plugin library are LGPLv2.1. It generally requires a GPU with OpenGL 3.0 support; slower software-rendered releases are available. macOS release binaries require macOS 15 or higher.
