This is a Visual Studio extension that allows for easy logo image creation. It takes large source images and creates resized copies that are used for app logos and splash screens. Also, it can generate multiple scales for any image. The scaled images can be used in your Windows app.

Right click any .png or .jpg image and choose the new "Scale image..." context menu item. See full instructions on the VS gallery page: https://marketplace.visualstudio.com/items?itemName=PeterSpa.WindowsUniversalAppImageScaler
