HxD is a free full-featured hex editor developed and published by Maël Hörz in 2003, but has received frequent updates.

Features:

• Customizable display.
• Tabbed documents.
• Opens files, entire drives, and programs in memory.
• Can view data as bytes, 16, 32, and 64 bit integers, big and little endian, various string formats, dates, times, and even several machine code formats.
• Supports files up to 8 EB, and uses partial loading.
• Find and replace in hex or text for multiple data types.
• Creates checksum and hashes using many different algorithms.
• Byte-by-byte file comparison.
• Statistical view for how common bytes are.

Personal

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.
