FAQ

CZI to IFF Conversion

What are CZI files?

CZI (Carl Zeiss Image) is the native image format of ZEISS ZEN microscopy software. It stores multidimensional acquisitions with channels, z-stacks, time series and mosaic tiles, together with the full set of instrument and acquisition metadata.

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.
