PWP (or SFW) is a proprietary raster image format used by Seattle FilmWorks, a mail-order film processing company popular in the 1990s. When customers mailed in their film rolls, they received back prints and a floppy disk (or later CD) containing digital versions of their photos in this format.
The PWP format is essentially a JPEG stream wrapped in a proprietary header. However, the JPEG data often used non-standard quantization tables or inverted color channels, which meant standard JPEG viewers could not open them. Users had to use the 'PhotoWorks' software provided on the disk to view or convert them.
Prevalent in the mid-to-late 1990s as one of the first mass-market ways for consumers to get digitized photos before digital cameras became affordable. The company eventually rebranded to PhotoWorks and moved to standard formats.
