Disable Desktop Wallpaper JPEG Quality Reduction in Windows 10

Disable Desktop Wallpaper JPEG Quality Reduction in Windows 10: Whenever you set a JPEG image as desktop wallpaper you might have noticed that the desktop wallpaper isn’t as sharp as the original image, in short, the quality of the image is not same. This is because whenever you set a JPEG as wallpaper, Windows 10 automatically compresses and reduces the quality of the original image before setting it as the desktop wallpaper. This is done by the operating system in order to save disk space and improve the performance of Windows while displaying the desktop wallpaper image.

When you set a JPEG image as the desktop wallpaper or slideshow, the operating system imports the reduce quality of the original image and store it as the TranscodedWallpaper file in the %AppData%\Microsoft\Windows\Themes folder. Once this happens, Windows uses this image file from the TranscodedWallpaper file cache to set the desktop background.

Now, this feature is very important for a PC with moderate specifications but if you have excellent hardware then this doesn’t make sense as you can have the full HD wallpaper without any quality reduction as your desktop wallpaper. Unfortunately, Windows 10 doesn’t offer a method to disable the JPG wallpaper quality reduction in Settings but a registry fix can help you to disable this automatic image compression. So without wasting any time let’s see How to Disable Desktop Wallpaper JPEG Quality Reduction in Windows 10 with the help of the below-listed tutorial.
