What Happens to PNG Transparency
PDFs do not support transparency the same way PNG does. When a PNG with a transparent background is converted to PDF, the transparent areas are filled with white. This is standard behavior for all PNG-to-PDF conversion tools.
If your PNG has a transparent background and you want it to appear as a specific color in the PDF, add a solid background to the PNG first using an image editor before converting.

PNG files are lossless — they preserve every pixel exactly. This makes them ideal for screenshots, diagrams, charts, and text-heavy images where sharpness matters. JPGs use lossy compression, which is better for photos but can introduce artifacts in images with sharp edges or text.
For logos, UI screenshots, or any image with text, use PNG source files when converting to PDF for the sharpest possible output.
Combine Multiple PNGs Into One PDF
Upload multiple PNG files in one batch to combine them into a single multi-page PDF. Each PNG becomes one page. Use the drag handles on the thumbnails to set the exact page order before converting.
You can also mix PNG and JPG files in the same upload — the tool handles both formats together in one PDF.

Open Image to PDF ToolFrequently Asked Questions
Does it keep the PNG quality when converting to PDF?
Yes. The converter embeds the PNG at full resolution with no resampling or compression. The PDF output quality matches the source PNG quality exactly.
Can I convert a screenshot PNG to PDF?
Yes, and screenshots work particularly well because they have perfect contrast and sharp edges. Drag your screenshot PNG into the tool and convert — it embeds cleanly at screen resolution.
What about PNG files with transparent backgrounds?
Transparent areas are filled with white when placed in the PDF. This is how all PNG-to-PDF converters work since the PDF format does not support full alpha transparency for embedded images.
Is there a page count limit?
No. Add as many PNGs as you need. There is no page cap or file count restriction.
