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.
The easy-to-use interface offers features such as searching and replacing, exporting, checksums/digests, insertion of byte patterns, a file shredder, concatenation or splitting of files, statistics and much more.
Editing works like in a text editor with a focus on a simple and task-oriented operation, as such functions were streamlined to hide differences that are purely technical.
For example, drives and memory are presented similar to a file and are shown as a whole, in contrast to a sector/region-limited view that cuts off data which potentially belongs together. Drives and memory can be edited the same way as a regular file including support for undo. In addition memory-sections define a foldable region and inaccessible sections are hidden by default.
Furthermore a lot of effort was put into making operations fast and efficient, instead of forcing you to use specialized functions for technical reasons or arbitrarily limiting file sizes. This includes a responsive interface and progress indicators for lengthy operations.
