Hex dump

Waiting for input

Type some text to see its byte-level hex dump.

Left column is the byte offset (hex), middle is the payload in hex, right is the printable ASCII gutter (0 printable / 0 bytes). Pure client-side decode, nothing leaves your machine.

Frequently asked questions

What does the left column mean?

It is the byte offset of the row's first byte, in hexadecimal — the classic hexdump layout used by xxd and od.

Why do UTF-8 and UTF-16 views differ?

UTF-8 encodes characters in 1–4 bytes; UTF-16 (LE) uses fixed 2-byte code units. Same text, different byte layout.
