The .hdp file extension is most commonly associated with files containing HD photos. The HDP files store compressed raster images. This file format was developed by Microsoft. It is used for the creation of high-resolution photo images. HDP files are similar to JPG files, but the HDP file format uses a higher rate of compression and the compression format is lossless rather than lossy.
The .hdp file extension is also used for Magix Musstu files.
