FreeDMG can make internet enabled disk images for distribution to Macs as well as ISO/Joliet hybrid images for cross-platform delivery. Verbose preferences, and a built-in log window help users hide/display additional information about the imaging process.

From the hidden "resize" function of hdiutil to the adjustable compresion levels available for the UDZO format, this software attempts to unveil it all. Users have the option to overwrite exising files, and can choose to quit the program automatically after creating an image on launch. It is possible to encrypt images (password protect) with the click of a button.
