What is pgm file format
PGM (Portable Graymap) is a grayscale image format in the Netpbm format family. It stores images in various shades of gray and is typically used in scientific and graphic design applications where color isn’t necessary but detail in light and shadow is important.
How to open pgm files
PGM files can be opened with image editors like GIMP, Photoshop, and ImageMagick. Conversion tools are available online to convert PGM into more commonly used formats like JPG or PNG. Many Netpbm utilities also support PGM for manipulation and conversion.
What is jpeg file format
JPEG is a widely supported lossy image format used mainly for photographs. JPEG and JPG refer to the same encoding; the difference is usually only the filename extension. It reduces file size by discarding some image information and does not support transparency.
How to open jpeg files
JPEG files open in standard browsers, built-in photo viewers, mobile gallery apps, and most image editors. Use PNG or WebP instead when the workflow requires transparency.
