Converting PNG images to PDF is particularly useful when images contain transparency or sharp text: the PNG format is lossless and produces PDFs with high-definition graphics. OnlinePdfEditor converts one or more PNG images into a single PDF file, preserving the original quality.

You can upload screenshots, charts, logos or any other PNG images. The resulting PDF is compatible with all viewers and ready for sharing or archiving.

Conversion happens entirely in the browser without uploading anything online.

Frequently asked questions

Is PNG transparency preserved in the PDF?

PDF format supports transparency. You can choose to keep the transparent background or apply a white background for maximum compatibility.

Can I convert multiple PNGs into a single PDF?

Yes. You can upload multiple PNG images at once and they will be combined into a single PDF document, one per page.

What is the difference between converting PNG and JPG to PDF?

PNG is a lossless format ideal for logos, screenshots and graphics with flat areas. JPG is better for photos. Both produce high-quality PDFs.

Are my files uploaded to a server?

No. The conversion happens entirely in the browser. Your images never leave your device.

Does it work on smartphones?

Yes. It works on any modern browser on iOS and Android.
