Choose JPG or PNG for your purpose
JPG is a practical choice for photographs and smaller downloads. PNG keeps rendered text and line art crisp without lossy image compression, but the output can take more storage. Choose the format according to where you will use the pages and how much detail must remain readable.
The conversion renders PDF pages into images; the output is not an editable PDF and does not preserve selectable text as text. If you only need a page or two, split the PDF first. For a scanned page that needs searchable wording, use PDF OCR instead.
