Turning PDF pages into pictures is the quick way to put a page in a chat, a slide or a social post, or to show it on a device without a PDF reader.
JPG makes smaller files and suits scans and photos. PNG keeps text and lines sharper, with no faint halo around the letters, but the files are bigger. For a page that is mostly text you will share on screen, either works; for a scan, pick JPG.
Want only the photos inside the PDF, not whole pages? Use Extract images instead.
