Convert PWP to PGM

The PWP file extension stands for PhotoWorks Image File, associated with the PhotoWorks software developed by Seattle FilmWorks. Primarily used in the late 1990s and early 2000s for storing color images, PWP files are similar to SFW files and were commonly used for image downloads from the internet. Although the software is now discontinued, PWP files can be converted to standard JPG images using specific converters.

The Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.
