Byte patching, patch management, Copy-Bytes-As-Array for many common programming languages, string and hex search, Bookmarks, Goto, Huge file support, variable collumn count, custom encodings and much more
ImHex includes a full custom C++-like pattern language that allows easy highlighting, decoding and analyzing of file formats.
IPS patches and data import
Automatically decode base64 files to hex and apply IPS and IPS32 patches directly.
Changes made to a file can immediately be exported as IPS and IPS32 patches again too.
Integrated Disassembler and YARA
Disassemble a variaty of different instruction sets. From x86 over ARM Cortex-M Thumb code to PowerPC. Many configuration options are available.
Together with the integrated YARA rules parser it's a great way to analyze Malware.
Immediately identifiy known file types with the extensible file magic interface. Further analyze the data with byte distribution and entropy graphs.
Graphical data processor
Pre-process data with the easy to use data processor. Decrypt, transform or simplify the loaded data with the intuitive, node-based interface.
ImHex is completely free and open source under the GPLv2 license.
There's also unstable nighly builds available on GitHub Actions. They will have more features but can potentially be less stable and have more bugs.
