Convert pgm to pdf

What is the difference between .pgm and .pdf?

Description: A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.; The Portable Document Format (PDF) is a versatile file type designed to present documents in a manner independent of application software, hardware, and operating systems. Created by Adobe in the 1990s, PDF files can encapsulate text, fonts, images, and even interactive elements like hyperlinks, forms, and multimedia content. This format is widely used for its ability to preserve the original formatting of a document, ensuring that it can be viewed and printed as intended across different platforms.
