.PPM File Extension

24-bit color image formatted using a text format; stores each pixel with a number from 0 to 65536, which specifies the color of the pixel; also stores the image height and width, whitespace data, and the maximum color value.

The Portable Pixmap format uses an uncompressed and inefficient format compared to other bitmap image formats. Therefore, it is seldom used for storing large images.

Data file used to "flash" some Nokia mobile phones; sometimes used to change the language pack on a phone to support a different language; may also use the .PPM_B, PPM_C, or PPM_D file extensions.
