Information about PEF and PNG file formats

Name PEF PNG
Full name Pentax RAW file PNG - Portable Network Graphics
File extension .pef .png
MIME type image/x-pentax-pef, image/x-pentax-raw image/png
Developed by Pentax PNG Development Group
Type of format Image File lossless bitmap image format
Description PEF is a digital image format used in Pentax digital cameras such as the K3, K5, K10 and K20. Pentax cameras capture photos with unprocessed image data and information on the conditions when the photos were taken. The PEF format is based on the TIFF format - PEF uses a non-standard file header and includes additional image tags and encrypts some of the tagged data. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group.
Technical details RAW files are an intermediate format. They contain unmodified sensor data from the digital camera, packaged with metadata about the shot as well as a JPEG preview (for quick viewing). In Pentax-proprietary PEF files the data is both losslessly compressed and of a higher bit depth than that of JPEG. PEF files are 12-bit as a standard, however on the K-5, K-5IIs, and K-3 models they are full 14-bit RAW files. PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK.
