CRG to IFF Conversion: FAQ

What are CRG files?

The CRG format is associated with Calamus SL, an incipient desktop publishing software program released in the 1980s for the Atari ST, a then popular brand of home computers. Compared to previous programs with similar functions, the Calamus SL included innovative features for handling vector files, such as virtual objects, non-destructive vector masks and PDF import. Calamus was also the first DTP program to feature proprietary image formats, such as CPI and CRG. The program continues to be supported by the current owner, the German developer Invers Software.

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. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
