Why convert WDP to BMP?
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.
BMP stores every pixel uncompressed, so the image is exact and simple to read by any software that handles Windows bitmaps.
Frequently Asked Questions
How do I convert WDP to BMP?
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 an uncompressed BMP bitmap, ready to download.
Which program reads the HD Photo data in a WDP file for the BMP?
JxrDecApp, the reference decoder from Microsoft's open-source jxrlib. It decodes the picture losslessly, and that decoded image becomes the BMP.
How does a WDP file relate to JXR when it becomes a BMP?
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 BMP.
How big is the BMP image from a WDP file?
The image keeps the full pixel dimensions of the WDP photo.
What kind of BMP does the WDP converter create?
A standard Windows bitmap with every pixel stored uncompressed, so the image is an exact copy of the rendered result.
Is my .wdp file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
