Disable Wallpaper compression in Windows 11/10
Windows never actually applies the full quality image to the Desktop. It reduces the quality to enhance the system’s performance. Windows itself does not offer a method to disable the JPG wallpaper quality reduction in Windows 11/10, but a registry fix can help you disable this automatic compression feature. If you are unaware, Windows 11/10 computer stores the converted image as a TranscodedWallpaper file inside this directory: If you can manage to change its extension .jpg, you will be able to view the image used as the wallpaper. Anyway, using this registry fix, you can disable the automatic JPEG wallpaper quality reduction feature and improve the quality of your desktop background wallpaper. To do so, press Win+R key in combination to bring up the ‘Run’ dialog box. Type regedit and hit Enter to open the Registry Editor. Now navigate to the following key: In the right pane, right-click and create a new 32-bit DWORD parameter and name it JPEGImportQuality.
The value lies between 60 and 100. The default value is 85 which means that the compression is 85%. A value of 100 indicates a very high-quality wallpaper with no compression. Set the value to 100. Click OK and exit. Restart your computer. Now, set the image you would like to keep as wallpaper. It will be displayed without compression. It works in Windows 11/10 only.
