Why convert WDP to ICO?
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.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
Frequently Asked Questions
How do I convert WDP to ICO?
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 256 × 256 ICO icon, ready to download.
Which program reads the HD Photo data in a WDP file for the ICO?
JxrDecApp, the reference decoder from Microsoft's open-source jxrlib. It decodes the picture losslessly, and that decoded image becomes the ICO.
How does a WDP file relate to JXR when it becomes a ICO?
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 ICO.
Which part of the WDP becomes the ICO icon?
The whole image is used, fitted inside the 256 × 256 square with its proportions kept and a transparent surround.
What size is the ICO made from a WDP file?
The icon is 256 × 256 pixels, the largest standard Windows icon size. The image is fitted inside the square with its proportions kept and a transparent surround, stored as a PNG-compressed icon.
Is my .wdp file kept private?
