File to hex + ASCII converter
Client-side (javascript, no data is sent to server) file to hexadecimal code + ASCII (view similar to lister from Total Commander) conversion. Be careful with files > 1 MB (possible high resource consumption, e.g. Chromium 46 has serious problems when loading few MB of text into textarea, offline tools might be better for large files).
