HxD freeware

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.

HxD freeware - The Latest User Reviews
HxD freeware - The Latest Versions History Feb 11, 2021 New Release Hex editor: implement horizontal mouse wheel scrolling (including handling of Logitech driver bug)

Data inspector:
New: added LEB128/ULEB128 types (variable width integer types used in WASM and dwarf debug information)
New: introduce readonly type converters (to allow uniform error messages when attempting to change values, also for converter plugins)
Enhancement: better error handling so that typical errors are caught and a more specific error message is given
error message for plugin DLLs of wrong machine type (x86-32 vs. x86-64)
New: skip undefined or unreadable sections, such that Intel Hex and S-Record files can be created that have gaps
New: source code exporter option to set the maximum text column or bytes per lines (= array elements per line)
Checksums / digests:
New: custom checksum
can generate a checksum, with settable bitwidth for the checksum result, the checksum addends, and the endianness
useful for various exotic formats, such as ROM files Feb 28, 2020 New Release Restructured plugin interface:
easier to use from non-object-oriented languages, such as C
New: support signed hexadecimal numbers in data inspector (for Int8, Int16, Int32, Int64)
relative numbers are used in assembly, for example, so signed hexadecimal numbers should be supported
UInt8, UInt16, UInt32, UInt64 remain unsigned
Enhancement: integer types in the datainspector support a leading + sign
rewrote many conversion functions for more consistency and to deal with corner cases not handled well by Delphi's built-in functions
Enhancement: error message (when a relative- "goto" offset is not within the bounds of a file/stream) will mention both relative and obsolute offsets for easier reference
negative offsets are now also shown with a minus sign in hexadecimal
Fix: datainspector plugins fail to jump to the previous/next/first/last element Jul 6, 2019 New Release New: array navigation toolbar in datainspector (next/previous/first/last element)
allows to navigate types like ad-hoc arrays, that span the entire stream / file, extending left and right from the current element shown in the datainspector
all fixed-width data types support navigating forwards and backwards by default
backward navigation needs special support for variable-width data types like UTF-8 since UTF-8 is self-synchronizing, determining the previous element is possible (however, x86 assembly, for example, cannot be supported, since trailing bytes in an instruction encoding can also appear as leading bytes, which therefore only allows for an unambigious forward scan)
New: added Int24 and UInt24 types to data inspector (useful for wav files)
be sure to reset the data inspector row order in the options, if new types appear in the last rows
