Worth knowing before you use this
Each PDF page is rendered as a high-resolution image and placed as the full background of one slide — so the visual result looks exactly like your PDF. The text on each slide is not editable in PowerPoint, since it's part of the image, not separate text boxes. This is the same approach many conversion tools use by default for visual accuracy; if you need to edit the text afterward, you'd still need to retype it or use PowerPoint's own image-to-text tools.
