This is an experimental online hexdump utility written in Javascript.

This program may run slowly with files over 64k, by default all files are truncated to 64k. If you feel adventurous, you can opt to turn off this limit. On very large files this may freeze your browser. You will be warned when the output is truncated.

Above 64k also the formatting of the addresses is wrong, this will be fixed in a later version.

Also, this utility requires a browser that understands HTML5 local file access. It is only tested on Google Chrome, other browsers, especially non Webkit-based browsers may not work properly.

Select a file:
Process files over 64k in size anyway
