What size should a PowerPoint widescreen background image be?
PowerPoint uses 16:9 as the default slide ratio; it does not require one background-image pixel count. The 1920×1080 preset is a practical working canvas with a 16:9 aspect ratio. 1920×1080 is a Full HD working canvas, not a PowerPoint upload requirement.
Will a 1920×1080 image fill the slide without stretching?
It matches the 16:9 slide shape. The image can still crop if the deck uses another ratio or a fill mode, so confirm the slide setup first and review the edges after placement.
Should presentation images be JPG or PNG?
JPG is usually smaller for photographs. PNG is better for diagrams, screenshots, and graphics that need crisp edges or transparency. This resizer downloads JPG files.
