Profiles are sets of commonly used options that optimize an image’s visual quality, file size, encoding speed, and OCR reliability. The options within each profile have been carefully pre-selected and set to meet the encoding requirements of a specific type of image. For example, a color catalog page that is scanned at 300 dpi requires a different encoding process than a bitonal hand drawing that is scanned at 200 dpi. Instead of specifying all the options on the command-line, you can specify just the profile name that contains all the options.
The default profile for documenttodjvu is scan300.
