Summary
REHex is a free hex editor for reverse engineering and other work with binary data. Available for Linux, macOS and Windows, it supports files larger than 1 TB and can decode integer and floating-point values or show machine-code disassembly inline. Users can compare whole files or selected regions side by side, highlight and annotate byte ranges, and map virtual addresses. Editing tools include bit manipulation and checksumming; the program also supports Intel HEX import and export, bitmap visualization, and common text encodings such as ASCII, Unicode and ISO-8859-X. Binary Templates can add automatic annotations, while Lua scripting and plugins extend its functions. Downloads include Windows installers and ZIP archives, a macOS DMG, and Linux AppImages; packages are also documented for several Linux distributions and FreeBSD. The project identifies its license as GPL-2.0. Its download page lists version 0.64.0, released on 2026-04-03, as the latest release, and the project invites bug reports and feature suggestions through GitHub issues.
