Why convert WDP to WebP?
WDP is the Windows Media Photo and HD Photo extension for JPEG XR images, found in Windows Photo Gallery libraries and Microsoft imaging tools. The photo is decoded with the JPEG XR reference decoder at its full width and height, with its colours and detail carried into the image.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
Frequently Asked Questions
How do I convert WDP to WebP?
Drop your WDP file above and press Convert. Our servers decode the HD Photo data with Microsoft's reference JxrDecApp decoder into a lossless PNG, then encode that picture in the format you chose. The result is saved as a compact WebP image, ready to download.
Which program reads the HD Photo data in a WDP file for the WebP?
JxrDecApp, the reference decoder from Microsoft's open-source jxrlib. It decodes the picture losslessly, and that decoded image becomes the WebP.
How does a WDP file relate to JXR when it becomes a WebP?
WDP and JXR hold the same JPEG XR format under different extensions, so both are decoded in exactly the same way and produce the same WebP.
How big is the WebP image from a WDP file?
The image keeps the full pixel dimensions of the WDP photo.
How much smaller is the WebP from a WDP file?
WebP typically produces files around a quarter to a third smaller than JPG at similar visual quality, and far smaller than PNG, while text and lines stay clear.
