What is a PPM file?

PPM (Portable Pixmap) is an image format developed by Netpbm, widely used for storing high-quality color images. It is a simple text or binary format supporting the RGB color model, suitable for image processing and computer graphics. Compared to more complex formats like JPEG or PNG, PPM offers higher transparency and readability, making it ideal for programming and debugging. Additionally, PPM files are typically uncompressed, ensuring lossless image quality.

PPM is part of the Netpbm format family, which includes PBM (black and white images), PGM (grayscale images), and PPM (color images). These formats are simple and easy to parse, making them perfect for developing and testing image processing algorithms. Recommended tools include GIMP and ImageMagick.
