PDF to PNG — export crisp, lossless page images fast

When you turn a PDF page into an image you have two real choices, and the format matters. PNG is lossless, so the text stays crisp, the thin lines stay sharp, and the flat colour blocks stay clean — none of the smeary halos that JPG compression leaves around letters and diagram edges. If a page area is transparent, PNG can carry that transparency straight through instead of painting a background behind it. That makes these exports the right pick for editing, layering a page into a design, dropping a clean screenshot of a page into a doc, or anywhere sharp edges do the talking.

Every page you select comes out as its own PNG, numbered in page order, rendered at the resolution you choose. There is no quality slider here, and that is on purpose: PNG is lossless, so there is nothing to trade away. There is no forced background either, because PNG keeps whatever transparency a page holds. Your two dials are the page range — export the whole file or something like 1-3,5 — and the DPI, from a light 72 up to a print-grade 300. Higher DPI gives you a bigger, sharper image; lower DPI keeps things quick and small.

A few honest notes so nothing surprises you. Each PNG is a raster snapshot of the page at the DPI you picked — the words become pixels, so they are not selectable, not searchable, and this is not OCR. If you need text you can highlight, a PNG is the wrong finish line. PNG files also run larger than the JPG version of the same page, sometimes a lot larger, which is the price of lossless quality and transparency; if small files matter more than sharp edges, reach for PDF to JPG instead. And remember that pushing DPI up makes each image both sharper and heavier.
