One image per page. Every page is filled white first, so transparent areas of a PNG come out white and consistent. "Fit to image" makes each page exactly the pixel size of its image; A4 and Letter centre each image on a standard page with the margin you choose.
How this PNG to PDF tool works
Each PNG you add is decoded in your browser to read its size and a small thumbnail is shown. When you convert, the images are placed one per page (in list order) into a new PDF with the pdf-lib library, and the PDF is offered as a download. Nothing you add or generate is ever sent to Docspira or anywhere else.
A PNG keeps its full pixel detail; it is embedded losslessly. Because a PDF page is transparent by default, each page is painted white before the image is drawn, so a PNG with a transparent background looks the same in every viewer. Images of different sizes are handled independently: with "Fit to image" every page matches its own image; with A4 or Letter every image is scaled to fit the page and centred.

Before you start
PNG transparency is preserved only where the PDF viewer supports it; check the output if a transparent design is critical.
