Preon is described as 'Aims to provide a framework for dealing with binary encoded data; or more specifically, it aims to deal with situations in which bytes are considered to be overkill. The project is named after the "point-like" particles, conceived to be subcomponents of quarks' and is an app in the development category. There are more than 10 alternatives to Preon for a variety of platforms, including Mac, Windows, Linux, Android and BSD apps. The best Preon alternative is HxD, which is free.

010 Editor is a professional text/hex editor designed to edit any file, drive, or process on your machine. Using Binary Templates technology, 010 Editor allows a binary file to be parsed into a data structure that can be understood.




BinEd is a hex editor tool, which allows to directly browse and edit content of any file or binary data.




WinHex is a hexadecimal editor capable of opening disks, sectors, files (native support for FAT, NTFS, Ext2/3, ReiserFS, Reiser4, UFS, CDFS, UDF) and physical memory (RAM). It can read, write and extract data for a further forensic analysis.

Kaitai Struct is a formal language for binary format specification that can be compiled into parser code in Java, JavaScript, Python and Ruby.
You got a binary file and don't know its contents. Or some software creates binary files where you have a specification but don't want to decode them manually.






DHEX is a more than just another hex editor: It includes a diff mode, which can be used to easily and conveniently compare two binary files. Since it is based on ncurses and is themeable, it can run on any number of systems and scenarios.



Tweak is a hex editor. It allows you to edit a file at very low level, letting you see the full and exact binary contents of the file. It can be useful for modifying binary files such as executables, editing disk or CD images, debugging programs that generate binary file formats...

Use the built-in hex editor, get MD5, SHA1, SHA256 hashes and Base64 with one click, or change the modified and created dates.
