File extension PGF description:
PGF is an image file format for natural and aerial images, which offers both lossless and lossy compression.
Because of its progressive resolution/quality enhancement, it is best suited for the Internet. Just after a few per cent of data transfer a thumbnail image is displayed. Then the resolution/quality constantly improves up to the maximum.
PGF convinces by its compression and decompression speed. The image quality remains very good thereby and is usually better than with JPEG. The lossless compression of PGF results in shorter time in smaller file sizes compared with PNG and lossless JPEG.
