PowerPoint Widescreen Background Resizer
PowerPoint uses 16:9 as the default slide ratio; it does not require one background-image pixel count. Use this Full HD canvas for a sharp full-slide photo on modern projectors and screens. This preset creates a 1920×1080 JPG while preserving the 16:9 slide shape; review the crop before adding it to your deck.
