PEF to RIFF Conversion: FAQ

What are PEF files?

The PEF image format is used for creating RAW images with Pentax cameras. Shooting in RAW mode allows the camera to capture everything its sensors can register, thus preserving a huge amount of details — as opposed to JPEG or other compressed formats, which have predefined settings and are processed automatically. With PEF images, photographers have more freedom to change the image during digital post-processing without affecting its quality. With the help of specialized software, aspects such as lights, exposure and shadows can be customized in the image, highlighting or hiding particular details.

What are RIFF files?

The Resource Interchange File Format RIFF is a structured multimedia container format developed through a collaboration between Microsoft and IBM in 1991. As an adaptation of the Electronic Arts Interchange File Format (IFF), RIFF implements a tagged chunk architecture where each data segment contains a 4-character identifier, 32-bit size field, and payload data. This design enables hierarchical organization of heterogeneous multimedia streams while maintaining platform-independent data representation through strict little-endian byte ordering.
