Screenshot of HxD.

HxD is a free full-featured hex editor developed by Maël Hörz in Object Pascal in 2003, and has received frequent updates over the years.


  • Customizable display.
  • Tabbed documents.
  • Can open files, entire drives, and running programs.
  • Can view data as 8 to 64-bit integers (big and little endian), various string formats, dates, times, and even several x86 machine code formats.
  • Supports files up to 8 EB, and uses partial loading for fast viewing.
  • Find and replace both support searching by hex (8-64 bit values big and little endian), text (ASCII and UTF-16), and even 4, 6, 8, and 10 byte floats.
  • Can checksum/hash files using 16 different algorithms.
  • Byte-by-byte file comparison.
  • Statistical view for how common bytes are.


I found HxD in July of 2020 while looking for a free replacement for Frhed. After seeing all the additional features and really good search capabilities, I switched over to using it.
