What this does: renders each PDF page as a raster image. Output is one image per page, bundled as a ZIP if there are multiple pages.

DPI guide: 72 = screen quality, 150 = good for slides, 200 = good for print preview, 300 = print quality, 600 = archival. Higher DPI = larger files (a 10-page PDF at 600 DPI can be 50+ MB).

Format: PNG is lossless and best for diagrams / text-heavy pages. JPG is smaller but lossy — best for photo-heavy pages.
