How to png to pdf

  1. Drop one or more PNGs.
  2. Order them if there are several.
  3. Press Convert and download.

What happens to your file

PNG pixels are embedded losslessly, so screenshots keep every crisp edge. Transparent regions have no colour of their own and show as white on paper and in most viewers.

Pages take each image’s exact size.

Questions

Why is my transparent background white?

PDF pages have a white backdrop. If you need the transparency, keep the PNG; the PDF is for printing and sharing.

Can I mix PNG and JPG?

Yes; each is embedded in its own format.
