Multi-GB mmap hex & ASCII binary editor, data inspector & binary diff
A fast, independent Linux binary file editor and analyzer inspired by FlexHEX workflows. Disclaimer: This project is an independent open-source tool and is not affiliated with, sponsored by, or endorsed by Heaventools Software or any third-party software vendors.
PAGED MULTI-GIGABYTE HEX & ASCII ENGINE
- Open multi-gigabyte binary files instantaneously with constant minimal RAM usage using os.pread and mmap paged windowing plus 64-bit offset jumping.
- Edit bytes directly in Hex or ASCII panes with a full reversible edit journal, Undo/Redo history, optional backup copy, and verified disk saves.
LIVE DATA INSPECTOR, SEARCH & BINARY DIFF
- Decode 8, 16, 32, and 64-bit signed/unsigned integers (Little-Endian and Big-Endian), IEEE-754 float32/float64, UTF-8, and UTF-16LE values live.
- Search Hex sequences (with wildcard support), ASCII, UTF-16LE, or numeric values; compute block Shannon entropy and CRC32/MD5/SHA-1/SHA-256 digests.
- Compare any two binary files side-by-side with difference region navigation and CSV or HTML diff report export.
