Which MIME types are related to file extension ".wdp"?
The .wdp file extension is associated with 2 MIME types:
image/jxr, image/vnd.ms-photo.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .wdp Files
WDP files are image files that use advanced compression and extended color support.
They rely on the JPEG Extended Range standard (MIME type image/jxr) and are also known as HD Photo (MIME type image/vnd.ms-photo).
These files store high-dynamic range images with extra detail and superior color accuracy.
They are most common in Windows environments and are supported by applications like Windows Photo Viewer, Microsoft Photos, Adobe Photoshop (with plugins), and IrfanView.
- High-Resolution Imaging: Ideal for photos needing enhanced detail and color fidelity.
- Advanced Compression: Offers improved quality at reduced file sizes.
- Windows Integration: Built for systems using Microsoft’s imaging technology.
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 a .wdp file?
A WDP file is a raster image saved in the Windows Media Photo format, which was a precursor to the modern JPEG XR standard. It supports advanced features like high dynamic range (HDR), transparency, and lossless compression, often associated with the MIME type image/vnd.ms-photo.
How do I open a WDP file on Windows?
You can open these files natively using Microsoft Photos or the legacy Windows Photo Viewer included with the operating system. Popular third-party image viewers like IrfanView, FastStone Image Viewer, and XnView also support the format.
Can I convert WDP files to JPG or PNG?
Yes, converting WDP is recommended for compatibility. You can use software like IrfanView or Paint.NET to open the WDP file and use the "Save As" feature to export it as a standard JPEG or PNG.
Why doesn't my web browser display WDP images?
Most modern web browsers (such as Chrome, Firefox, and Safari) do not natively support WDP or the related image/jxr content type. To ensure images are visible on the web, you must convert them to widely supported formats like WebP or JPEG.
Is a WDP file the same as a JXR file?
They are essentially the same format representing different stages of its evolution. WDP stands for Windows Media Photo, which was later renamed to HD Photo and eventually standardized internationally as JPEG XR (JXR).
How can I view WDP files on a Mac?
macOS Preview does not natively support WDP files. Mac users typically need to download third-party viewers such as XnView MP or use Adobe Photoshop with a JPEG XR plug-in to view or edit these images.
What are the advantages of WDP over standard JPEG?
WDP files offer higher compression efficiency, meaning they provide better image quality at smaller file sizes compared to standard JPEGs. They also support 16-bit color channels for higher color accuracy, which is useful for professional photography.
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.
