PDF to PPT
Put each PDF page on its own slide as an image — not editable text.
The slides come out as pictures. Each page is rendered as an image and placed on its own slide, so the deck looks exactly like the PDF — but the text isn't selectable or editable, and there are no shapes or text boxes to move around. It's for presenting and sharing, not for rewriting.
Resolution
Standard is sharp on a projector. High is for a deck that will be zoomed into or printed, and makes a noticeably larger file.
The slide shape is picked from the first page — 16:9 for a landscape PDF, 4:3 for a portrait one — and each page is centred at its own proportions, so nothing is stretched or cropped. Up to 50 pages at a time; use Split PDF to take a section out of a longer file first. Everything runs in your browser, so the PDF is never uploaded.
