PNG background and placement
Transparent areas appear over the specified page background
The PDF page background is white by default. Changing the background color also changes the appearance of transparent areas in the PNG and the margins around the image.
Image order and page order
Each image becomes one PDF page, starting with the first image. Check the order before saving.
Empty space may remain even with no margins
Images are fitted within the page while preserving their aspect ratios, so images whose aspect ratio differs from the paper leave empty space around them. Choose paper, orientation, and placement to suit your use.
Frequently asked questions
How do transparent areas in a PNG appear in the PDF?

Can I turn multiple PNGs into one PDF?
