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.
This format is a vector images file in the Sketch Drawing program, which serves to edit and create interface designs, applications and software shells. SK-files contain objects and layers which can be edited independently of each other.
