JPG to IFF Conversion: FAQ

What are JPG files?

JPG is one of the most popular image file formats currently in use, often referred to as a standard for uploading images online and for displaying photographs. One of its main advantages is providing a good image quality in a relatively small file size, which is easy to store and transfer. JPG uses a type of compression that prioritizes the quality of some image sections over others, thus assuring that most favorable quality/size ratio.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer.
