Convert PGM to JPE

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.

The JPE file extension stands for Joint Photographic Experts Group. It is a widely used image format known for its efficient compression and high quality, making it ideal for digital photography and web use. Originating in the late 1980s, the JPE format was developed to enable the effective storage and transmission of photographic images. Its primary purpose is to reduce file size without significantly compromising image quality, thereby optimizing storage and facilitating faster file transfers in computer technology contexts.
