Hex Viewer

Open any file and inspect it as a classic hex dump with an ASCII gutter, plus pull out the readable strings.

Open any file from your device and read it as a classic hex dump: an offset column, the raw bytes in hexadecimal, and an ASCII gutter on the right. Everything runs in your browser, so no file ever leaves your device. Use the strings scanner to pull out readable text that may hide coordinates or other clues.

How it works

A hex dump shows the exact bytes of a file. Each row begins with an offset (the position of the first byte on that row, counting from zero), then lists the bytes in hexadecimal, and ends with an ASCII view. Bytes in the printable range (space through tilde) appear as their character, and everything else shows as a dot.

Large files are only rendered from your chosen start offset up to the byte limit, so the page stays responsive. A note tells you when the view is truncated and how many bytes the file holds in total. Adjust the start offset and limit to walk through a big file in chunks.

The strings scanner reads the whole file and reports runs of printable ASCII characters that meet your minimum length. Hidden coordinates, file paths, and embedded notes often turn up here even in binary files. Output is capped so very large files stay responsive.
