Converting PDF to JPG: which settings to choose
Resolution (DPI) decides how sharp the images are. 72–96 DPI is enough for screen previews, 150 DPI is a good default for sharing and presentations, and 300 DPI matches print quality. An A4 or Letter page at 300 DPI is about 2500 × 3500 pixels.
JPG gives the smallest files and suits photos and scans. PNG is lossless and keeps text and diagrams perfectly crisp (and supports transparency). WebP combines small files with high quality and is supported by all modern browsers and websites.
If you want the photos that were placed in a PDF rather than pictures of whole pages, choose Extract images. JPEG photos are saved exactly as stored in the file — no quality loss — and the camera metadata can be stripped at the same time. All of this happens inside your browser; the PDF never leaves your device.
