Frequently Asked Questions

Is this PNG to PDF converter free?

Yes, ClonyPDF is completely free to use. There are no hidden charges, daily limits, or requirements to sign up.

Does converting PNG to PDF reduce image quality?

No. Our tool uses advanced compression that reduces file size while maintaining visual clarity. You can convert PNG to PDF without losing quality suitable for printing.

How do I convert transparent PNG to PDF without the background turning black?

This is a common issue with standard converters. Our tool detects the alpha channel (transparency) in your PNG and automatically fills it with white before conversion, ensuring a clean document.

How can I combine multiple PNG files into one PDF?

Simply upload all your PNG files at once. Our tool allows you to reorder them and will merge them into a single multi-page PDF document automatically.

Is it safe to upload my personal documents?

Absolutely. We use SSL encryption for file transfers. Furthermore, your files are processed automatically and deleted permanently from our servers after 2 hours. We do not view or store your data.

Can I use this tool on my mobile phone?

Yes, our website is fully responsive. You can use it as a mobile PNG to PDF converter on Android or iOS devices directly from your browser.

What is the best page size for PDF conversion?

For most official documents, resumes, and government uploads, A4 is the standard size. For receipts or photos, "Fit to Image" is often the best choice.

Why does the background turn black on other converters?

PDFs do not inherently support transparency in the same way PNGs do. If a converter doesn't "flatten" the image onto a white layer, the transparent areas are often rendered as black.

How can I convert PNG to PDF under 1MB?

Our tool optimizes file size by default. If your original images are very large, the resulting PDF is efficiently compressed to help meet strict file size limits like 1MB or 2MB.

Does this tool add a watermark to my file?

No. We respect your professional needs. The final PDF will be clean and free of any watermarks or ClonyPDF branding.
