Overview

Still Picture Interchange File Format (SPIFF) is an image file format based on the JPEG interchange format. It supports both lossy and lossless compression. It is not widely used.

It overlaps the JPEG standard. Some SPIFF files are valid JPEG files, and of those, many will be displayed correctly by a typical JPEG/JFIF viewer, even if it knows nothing about SPIFF.

It also supports additional image types and compression schemes that are incompatible with JPEG.

Format

SPIFF files contain a JPEG APP8 segment, with an identifier of "SPIFF".
