The PNTG file type is associated with Mac Paint, a pioneering graphics editing program developed for the Macintosh computer in the mid-1980s. It was one of the first widely used bitmap-based painting programs, allowing users to create and edit black-and-white images with a variety of drawing tools. PNTG files contain the graphical data created within Mac Paint, storing the pixel information that composes the image. Despite its historical significance in the evolution of digital art and graphic design software, Mac Paint and the PNTG format are largely obsolete, replaced by more advanced graphics formats and editing software.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
