Find what you're looking for with fast searching. * Smart saving. Hex Fiend knows not to waste time overwriting the parts of your files that haven't changed. * Data inspector. Interpret data as integer or floating point, signed or unsigned, big or little endian... * Smooth scrolling. No separate pages - scroll like any text document.
