Hex Dump Viewer
Paste text to see a hexdump-style offset, hex bytes, and ASCII view.
See the raw bytes
A hex dump reveals the exact bytes behind text — invaluable for spotting hidden characters, encoding issues, or byte-order marks. This viewer lays out your text in the classic three-column format used by xxd and hexdump.
Each row shows a byte offset, sixteen bytes in hexadecimal, and the printable ASCII on the right, with non-printable bytes shown as dots. “Hello, world!” dumps to a single tidy row.
Accurate and private
It encodes your text as UTF-8 and formats the dump in your browser, so nothing you paste is uploaded.

How is the text encoded?
As UTF-8 bytes, so multi-byte characters expand into several bytes, exactly as they are stored.
Why 16 bytes per row?
It is the traditional width that lines up cleanly and matches most command-line dump tools.
