Frequently Asked Questions
Will transparent backgrounds be lost when converting PNG to PDF?
PNG transparent backgrounds will appear as white in the PDF since PDF pages have a white background. This tool provides a background color option to automatically fill transparent areas with your chosen color.
Will image quality decrease after converting PNG to PDF?
No. This tool embeds PNG images into the PDF as-is without re-compression. PNG's lossless compression is fully preserved, so image quality does not decrease.
Are my images uploaded to a server?
No. This tool runs entirely in your browser using the jsPDF library. Image data never leaves your device and is not uploaded to any server, ensuring your privacy.
How many PNG images can I convert at once?
You can batch upload multiple PNG images, each becoming one page in the PDF. We recommend no more than 50 images at a time since PNG files are typically larger and require more memory.
Can I set the PDF page size?
Yes. Choose from A4, A3, Letter, Legal, or auto-fit to image dimensions. Orientation options include portrait, landscape, or auto-detect. You can also set image fit mode and page margins.
