Portable GrayMap Bitmap File

The Portable GrayMap Bitmap (.PGM) file format is the ideal choice for seamless exchange of grayscale images across various hardware and software platforms.

From 1-bit monochrome to 16-bit grayscale, it allows users to customize their images by selecting the most suitable resolution and depth for their application, be it image processing and manipulation or basic graphic display.

Offering high levels of image quality and lossless compression, PGM ensures optimal results when sharing or archiving digital images at a fraction of the cost.
