File to Hex Dump
Upload any file and download a text rendering of its bytes. The default 'Hex dump' format mirrors classic xxd output — 16 bytes per row, offset prefix, ASCII column on the right — perfect for inspecting binary protocols, firmware images, or unfamiliar file formats. Other formats: 'Plain hex' (one continuous lowercase string, no separators — round-trippable through hex-to-file), 'C array' (ready to paste into C/C++ source), and 'Comma-separated bytes' (0xHH, 0xHH, …). Conversion is local — the file never leaves your browser.
