About .hdp Files
HDP files are image files that store high-quality photo data using advanced compression. They are linked with two MIME types: image/vnd.ms-photo and image/jxr.
They follow the Windows Media Photo and JPEG XR standards. These formats support high dynamic range and improved color accuracy.
- Efficient Storage: Optimizes file size while preserving image details.
- Advanced Color: Handles a broader range of colors and contrasts.
- Windows Integration: Opens in Microsoft Photo Viewer, Windows Photos, and may also work with apps like Adobe Photoshop (with plugins).
Based on information from FilExt.com, HDP files were designed to enhance image quality and compression efficiency. Use a compatible application to open, view, or edit HDP files.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an HDP file?
An HDP file is a high-definition image saved in the Windows Media Photo format, which was the predecessor to the modern JPEG XR standard. These files support advanced features like high dynamic range (HDR) and better compression than standard JPEGs. You can find technical details under the MIME type image/vnd.ms-photo.
How do I open an HDP file on Windows?
You can open HDP files natively using Microsoft Photos or the legacy Windows Photo Viewer included with the operating system. Third-party image viewers like XnView and IrfanView are also excellent free alternatives that handle this format easily.
Can I view HDP files on a Mac?
macOS Preview does not natively support the HDP format. To view these files on a Mac, you should download a cross-platform viewer like XnView MP or convert the file to a common format like JPG or PNG using an online conversion tool.
How do I convert an HDP file to JPEG?
You can convert an HDP file by opening it in software like Adobe Photoshop (which may require a plugin) or GIMP, and then using the "Export" or "Save As" feature to select JPEG. Alternatively, numerous free online file converters can handle this transformation instantly.
What is the relationship between HDP and JXR files?
The .hdp extension stands for "HD Photo," which was Microsoft's original name for the format before it became the standardized JPEG XR (.jxr). While the extensions differ, the underlying technology is largely the same, and both often share the MIME type image/jxr.
Why are HDP files not displaying in my web browser?
Most modern web browsers (such as Chrome, Firefox, and Safari) do not provide native support for displaying HDP images. If you need to display an image on a website, you must convert the HDP file to a web-friendly format like WebP, PNG, or JPG.
Are HDP files lossless or lossy?
The HDP format is versatile and supports both lossless (perfect quality preservation) and lossy (smaller file size) compression. This flexibility allows photographers to choose between maximum image fidelity or efficient storage space.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
