ReHex is a cross-platform hexadecimal editor designed for reverse engineering, binary analysis, and low-level file manipulation. It supports editing extremely large files exceeding one terabyte. Users can inspect raw bytes and decode integer, floating-point, and text representations. Inline machine code disassembly helps analyze executable instructions directly within binary files. Advanced tools allow byte ranges to be highlighted, annotated, and mapped to virtual addresses. A comparison feature identifies differences between complete files or selected regions. Binary templates automatically interpret structured data, while Lua scripting enables custom analysis workflows. Additional functionality includes bitmap visualization, bit manipulation, checksums, and Intel HEX importing and exporting. ReHex runs on Windows, macOS, Linux, and BSD.
