13 Best Free Hex Viewer Software For Windows

Here is a list of best free hex viewer software for Windows. Using these software, you can open, view, and even edit hex files. The hex file format is used to store machine language code in the hexadecimal form. It is mainly used to store programs that are going to be transferred to Microcontrollers, ROM, etc. In the hex file, you can view hex codes that are made up from 16 digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F). Generally, hex file structure is composed of three sections: Offset value section, Hex code presentation section, and character value section. These software show you the code structure in a proper manner and also provide some additional tools to change viewing experience like zoom in/out tools, color coding of codes, search tool, etc.

Most hex viewers are proper hex editors and they come with essential editing tools like Find and Replace, Manual edit, cut/ paste code, etc. Some software can also edit decimal codes, octal codes, ASCII codes, binary codes, etc. Some of these hex viewing programs let you add multiple files, apply logical operators, insert other files, insert bytes, etc.

iBored

iBored is yet another free hex file viewer software for Windows. It is mainly used to edit disk sectors, but you can also view and edit hex files in it. To view the hex file, you need to drop the intended hex file on its interface. The hex codes can be viewed in Raw tab, but the data associated with the hex code cannot be viewed. It also lacks tools to improve the reading experience but still, a useful Find tool to find hex is available in the BlockView tab.

If you want to edit the code, then you need to enable Write mode by going to Disk > Make Writable. After editing, you can save the code in the original file in the same format as no option to separately save the edited document is available.

In my opinion, it is not a very user-friendly software and it also lacks most basic tools required to view and read a document properly.

WinVi

WinVi is a free and portable hex viewer software for Windows. It is a simple and straightforward software that can handle a single file of up to 2 GB.

The main feature of this software is its ability to differentiate codes using the color. Basically, any hex code starts with 0 (zero) is displayed with red color and all other code in blue. Good amount of spacing between sets of codes and color codes gives a really good viewing experience. Besides this, it does not have any other tool to improve the hex file viewing. Still, some useful features and tools like multi-window interface, search, cut, paste, etc. are available.

This software also allows editing for which you need just need to select a code and replace that with new value. Cut and paste functionality can also be used to replace a big chunk of code at once. Once done, you can save the code as PDF using the print option or as TXT, DLL, HEX, etc. formats.

Both the edited and non-edited codes can be saved as PDF or as TXT, DOC, HEX, etc. formats.

This hex file viewer also comes with various handy tools and features like Simplified search for Unicode, Fast search algorithm (Quicksearch), Bookmarks, Common tools (cut, copy, paste, find & replace, etc.), and more. All of these tools help you at viewing as well as in editing of codes.

Funduc Software Hex Editor

Funduc Software Hex Editor is another free hex viewer and editor software for Windows. It is a lightweight hex editor comes with only basic editing capability like Manual Edit (by directly selecting and replacing the code with new one), Edit using basic tools (cut, paste, select, etc.), etc. It is not intended to used as full-fledged hex editor. Still, as a hex viewer, it works fine as it can open decent sized multiple files at a time.

In terms of file, it supports all standard hex code files like TXT, EXE, HEX, etc. Plus, after editing, you can save the file in any one of the supported input file formats.

wxHexEditor

wxHexEditor is a free and cross-platform hex editor. It is available for Windows, Linux, and MacOSX. It supports multiple tabs so that you can easily view and edit multiple hex files at a time. The hex code displayed by it is pretty clean and has the right structure; besides this, no other specific feature to improve reading is available. However, for editing, there are still some good features like writeable and direct write modes, find and replace, cut, copy, paste, insert, etc. Plus, after editing, you can change the format of hex file to TEXT, DLL, DOCX, etc.

The good property of this software is that it uses 64-bit descriptors that allows it to handle a file of size up to few exabytes. Plus, it also does not load the whole file at the RAM at once to load files quickly. Here, you also get features which let you copy/edit your Disks, HDD Sectors with it. Some additional tools like Calculate Checksum, Compare File, and XOR view are also available. In my opinion, it is a feature-rich software, but not that great for viewing due to lack of viewing and reading specific features.
