Hex Dump Calculator

About this calculator

A hex dump is the classic way to inspect raw bytes: the data is laid out 16 bytes per row, with each row starting with the byte offset, followed by the 16 bytes shown as two-digit hexadecimal values, and finished with an ASCII gutter showing the printable characters (with non-printable bytes rendered as a dot).

This is the same layout produced by classic command-line tools like xxd or hexdump, and it's a everyday utility for programmers, reverse engineers, and forensic analysts who need to see the exact byte-level content of a file, network packet, or memory region — spotting file signatures, debugging binary formats, or checking for hidden non-printable characters that a normal text view would hide.
