HxD-Freeware Hex Editor, Disk Editor and Memory Editor

Hex editors are really very useful for programmers and people who are interested in modifying files in HEX formats. Recently I was looking for a good hex editor to modify the headers of some Image files and found HxD. HxD is a Freeware Hex Editor to edit large files. You can also use it as a Disk Editor for raw editing of Hard disks. The simple interface will help you to get your work done very easily without much complications. It offers searching and replacing, checksums/digests, exporting, insertion of byte patterns, concatenation or splitting of files, a file shredder, statistics and many more features.


With HxD you can even edit your drives and memory. 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. You can easily edit the Drives and memory in the normal way as you edit the regular files including support for an undo option.

Features of HxD

  • Availability of a Portable version.
  • RAM-Editor to edit the main memory.
  • Disk-Editor for RAW reading and writing of disks and drives(HDD, USB etc).
  • Supports file sizes upto 8EB(1,024TB = 1PB, 1,024PB = 1EB).
  • View data in Ansi, DOS, EBCDIC and Macintosh character sets
  • Checksum-Generator: Checksum, SHA-1, SHA-512, CRCs, Custom CRC, MD5 etc.
  • File Shredder, Splitter and Joiner.
