Ptiff is a type of image file that is created by compressing a TIFF (Tagged Image File Format) image using a wavelet-based encoding, known as pyramidal encoding. This type of file can store both lossy and lossless compressed images and is often used for storing large-scale images such as aerial photographs or medical images.
