How do I convert PNG to PDF?

Upload your PNG images to this tool, arrange them in the desired order, and click Convert to PDF. Multiple PNG files are combined into a single PDF. All processing runs locally in your browser — no server upload needed.

Is PNG transparency preserved in the PDF?

PDF viewers display transparent areas as white by default. If your PNG has transparency, the transparent areas will appear white in the PDF. For specific background colors, add them to your PNG before converting.

Can I mix PNG and other image formats?

This tool is optimized for PNG files. For mixed format support, use our general Image to PDF tool which accepts JPG, PNG, and WebP images in a single conversion.

What page sizes are supported?

Standard page sizes include A4, Letter, A3, and Legal in both portrait and landscape orientations. You can also adjust margins to control image placement on each page.

Is there a limit on the number of PNG files?

There's no hard limit on the number of files. However, since processing happens in your browser, very large batches (100+ high-resolution PNGs) may be slow depending on your device's memory.
