.PGF File Extension

A PGF file is a bitmap image created in the Progressive Graphics File (PGF) format. It supports lossy and lossless compression and a variety of color models, including indexed color (256 palette size), grayscale, RGB color, ARGB color, l*a*b color, and CMYK color.

The PGF format was designed to improve on the JPEG standard by reducing compression time and increasing compression ratios. The format offers progressive transmission, which means the image can be viewed at a low quality before all of its data is fully downloaded and then increases as more data is received. The format also includes representation of multiple resolutions, which means that it does not need to store separate preview images, such as thumbnails.

NOTE:PGF was developed at the same time as JPEG 2000 and initially released in 2000. The format was developed at the Institute of Theoretical Computer Science at ETH Zurich university.

Game file used by Pokémon Black and Pokémon White, the fifth generation of Pokémon games for the Nintendo DS game device; stores data for a mystery gift, which can be given to other players to unlock items and events in the game.

PGF files are located within Pokémon saved games (.SAV files) on Nintendo DS cartridges. They can be edited and imported into a SAV file using Pokesav or the Pokémon Mystery Gift Editor.
