The PGM file format is a graphics file format used to store grayscale images in either a text or binary format. The text format, also known as P2, enables easy manual editing of the image data due to it being stored in a human-readable format.

The format stores the monochrome image data using a range of values between 0 and 255, thus giving 256 shades of gray that can be used by the image. Colour is not supported by the PGM format.

PGM files are a legacy file format that can be opened with certain image editing applications that still support this format; alternatively, we have a set of PGM image conversion tools designed to convert PGM files to other, more modern formats, such as PNG.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.
