AnyToISO is the ultimate ISO Creator for Windows. It can create ISO from almost everything including all CD/DVD/BD images formats popular in Internet (NRG, MDF, UIF, DMG, ISZ, BIN, DAA, PDI, CDI, IMG, etc), CD/ DVD/ Blue-ray disks or simply from a local folder.
AnyToISO also can extract any of those formats plus ISO/ DEB/ RPM images. Most CD/DVD burning software works with ISO images and its native images only. Use the program for conversion before burning, because AnyToISO supports all CD/DVD/BD formats popular in Internet.
This program is available in two editions: Lite and Pro (Professional). Lite version is totally free but it cannot deal with files greater than a normal CD size (870 MB).
