PNG to PDF: Screenshots, Transparency and Size

PNG to PDF embeds each of your uploaded PNG images directly into a real PDF, one image per page, in your browser — genuinely reading and placing your image's actual pixels.

Step-by-step

1. Upload one or more PNG images.
2. Arrange them into your desired page order.
3. Set page size and orientation.
4. Convert and download the combined PDF.

What happens to transparency

PNG images often have transparent backgrounds (screenshots, icons, diagrams exported from design tools). Since a PDF page doesn't have a transparency channel, transparent areas are rendered against a white background — the same predictable behavior you'd see converting a transparent PNG to any non-transparent format.

Good uses for this

Turning a series of screenshots into one document for a bug report, compiling diagram exports into a single shareable file, or combining scanned pages saved as PNG into one PDF.

Troubleshooting

• "My transparent PNG has a white background now." Expected — PDF pages have no transparency channel, so transparent areas render as white.
• "The images came out in the wrong order." Check the upload order before converting — it maps directly to page order in the output.
• "The PDF file is quite large." PNG files, especially screenshots with lots of detail, can be large — run the result through Compress PDF if size matters.
