What is an HDP file?

The .HDP file extension stands for HD Photo, a raster image format developed by Microsoft. It’s also known as Windows Media Photo (WMP) or JPEG XR (Extended Range). HD Photo files are designed to offer higher compression efficiency and greater flexibility in representing image data compared to traditional formats like JPEG.

More Information.

The initial purpose of the HD Photo format was to provide a high-quality image format that could offer better compression ratios than JPEG, without sacrificing image quality. Microsoft intended for HD Photo to be used in digital photography, printing, and web graphics, where efficient storage and high image fidelity are crucial.

Origin Of This File.

The HD Photo format was introduced by Microsoft in 2006. It was developed as part of Microsoft’s push to create more efficient and flexible image formats that could be used across various platforms and applications.
