PEN to IFF Conversion: FAQ

What are PEN files?

The PEN raw photo format, specific to Pentax cameras, refers to the proprietary RAW file format used to store unprocessed image data directly from the camera's sensor. This format allows photographers to capture and retain the highest level of detail, dynamic range, and tonal information, providing extensive flexibility in post-processing.

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.
