Are the 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.

+1. I like the fact that it doesn't require an installer. Also, it is open source. –  Magnilex Aug 22 '13 at 13:17

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

alt text

(Though I usually use HxD.)

Just out of curiosity, how do you turn hex edit mode on in Vim? –  Kris Erickson Nov 29 '12 at 16:51

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. –  Ash Sep 2 '09 at 7:03
    
Thanks for the comment. I don't do much hex editing so I don't have much experience with it. –  Scott Sep 3 '09 at 19:09

Check out this Comparison of hex editors.

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. –  Django Reinhardt Feb 4 '10 at 14:33
    
+1 for working with big files –  Sarge Borsch Feb 23 at 23:17

Winhex is a decent tool for that.

This is a link to the StackOverflow 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.
