Are there some hex editors for Windows? Preferably open source or free since I don't need a hex editor all that often...

Things I do need is the ability to search in different types (text, raw hex, little endian short, big endian short, etc.) and viewing by type (same as searching types) starting at the selected byte. It would be nice to be able to create structs on the fly, so I can view binary blobs in the file. Binary file comparison is also a must, hopefully it would be smart and enable block detection.

I do know about the list on Wikipedia, but I don't really have time to try the 60 or hex editors, and I was wondering what other people use.

    The SO question isn't there anymore. Some of the best questions around here seem to be closed !?

    @Liviu - Yes, it is a shame. I have no idea why that particular question was removed. Marking a question as [Closed] is one thing, but removing it (and any existing answers) is another matter, and and it seems to me to be a bit excessive except in cases of abuse (spam, etc...).

    For some reason, every time I think "oh, that's exactly the question I was looking for" it appears to be closed...

    @ArturKlesun it's like when you google something and all the results for similar questions are just full of people saying to Google it.

Free Hex Editor (frhed), small and fast.

    +1. I like the fact that it doesn't require an installer. Also, it is open source.

    Its a bad hex-editor, cant load 4gb files even if you have 18gb ram free.

Personally, I use HxD (Free but not open source). Particular features of note include the ability to open very very large files, and you can modify raw disk data and open and edit data in RAM.

    HxD is a great free Hex Editor that handles massive files with ease. Definitely gets a +1 from me. Feb 4, 2010 at 14:33

  • does it provide option to disable disk edit? I worried my kid accidentally do it Jul 15, 2020 at 9:02

Notepad++ with a hex editor plugin. I was already using the text editor, so this makes for one less application installed.

    This plugin is flaky in my experience. It struggles with large files and switches to/from Hex mode at random.

  • Thanks for the comment. I don't do much hex editing so I don't have much experience with it.

  • It's not useful when you want to edit a big file that doesn't fit on memory.

UltraEdit has a hex editor mode:

For an old school DOS style display, ZTreeWin:

enter image description here

(neither are free / open source).


XVI32 is a freeware hex editor running under Windows 95, Windows 98, Windows NT, Windows 2000, and Windows XP.

Cygnus Hex Editor is a powerful file editor for Microsoft Windows. Unlike text editors, which are designed to edit files that contain text data, hex editors allow you to edit files that contain any type of data.

Free Hex Editor Neo is award-winning large files optimized freeware editor for everyone who works with ASCII, hex, decimal, float, double and binary data.

HxD is a carefully designed and fast hex editor which, additionally to raw disk editing and modifying of main memory (RAM), handles files of any size.

    No offense, but have you actually used any of these editors? I appreciate the work that goes in to googling and pasting the copy from the websites, but I was looking for recommendations from actual usage. Jul 28, 2009 at 15:13

    I was coming here to suggest XVI32, so upvote for that Jul 28, 2009 at 21:31

PSPad can edit in hex, and it's free too.

Since I can hexedit in Vim as well, I tend to say ... Vim!

(Though I usually use HxD.)

  • Just out of curiosity, how do you turn hex edit mode on in Vim? Nov 29, 2012 at 16:51

Winhex is a decent tool for that.

Enter image description here

This is a Stack Overflow version of the same question. There are a few more options so you can pick from the several recommended there if you do not like Winhex.


If you want a hex editor that works from the command line, I like Hexciting.
