What size should a PowerPoint standard background image be?
PowerPoint offers a Standard 4:3 slide ratio for older projectors and legacy decks. The 1024×768 preset is a practical working canvas with a 4:3 aspect ratio. 1024×768 is a practical 4:3 image canvas, not a required PowerPoint pixel count.
Will a 1024×768 image fill the slide without stretching?
It matches the 4:3 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.
