LWI to IFF Conversion: FAQ

What are LWI files?

LWI is a bitmap image format associated with an image processing program called LightWorks, developed by LightWork Design. This is a British company specialized in offering image design solutions for a variety of business sectors, including product design, point-of-sale configurators and animated content. LWI images are considered rare and might be difficult to open outside the LightWorks program.

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.
