Software Highlights
Free Hex Editor Neo is a feature-rich hexadecimal editor designed for advanced users who need precise control over binary data. It enables deep inspection and modification of files at the byte level, making it ideal for low-level programming, firmware editing, and forensic analysis.
The installer offers a portable mode, allowing you to save Free Hex Editor Neo to a USB flash drive and run it on any workstation with minimal setup. When used in portable mode, no traces are left behind in the Windows registry or on the host hard drive—perfect for system administrators and security professionals.
The interface is highly comfortable and efficient, featuring tabbed support for managing multiple files simultaneously. You can edit individual cells, enable insert mode, jump to specific offsets, search and replace patterns (or all occurrences), and view data in various formats including decimal, octal, binary, floating-point, and double-precision.
You can reduce column count, change byte order (endianness), export selections to files, merge and cut selections, fill fields with bytes or patterns, insert external files or hex data, modify individual bits, and encrypt or decrypt document data directly within the editor.
Free Hex Editor Neo includes a wide range of customizable toolbars—such as History, File Properties, and Structure Viewer—so you can tailor the workspace to your workflow. It supports logical bit shifting, case conversion, bookmarks, and opening file streams directly in the editor.
Additional advanced tools include file comparison, structure library management, data inspection, checksum generation, and built-in disassemblers for x86, x64, and .NET assemblies—making it a comprehensive toolkit for binary analysis and software development.
