View text as a hexdump -C style offset, hex and ASCII dump. Hex Dump Viewer is a free online tool from the ToolsRift Encoders & Decoders collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Type or paste text and the hex dump updates live. Each row shows the byte offset in hex, the 16 bytes as hex pairs, and an ASCII column where non-printable bytes show as a dot.
An 8-digit hex offset, up to 16 bytes shown as hex pairs (split into two groups of 8), and the same bytes rendered as ASCII inside |bars|.
Bytes below 0x20 or above 0x7e are non-printable, so they are displayed as '.' in the ASCII column — exactly like the Unix hexdump -C tool.
The text is encoded as UTF-8, so multi-byte characters expand into several hex bytes.
