Frequently Asked Questions

Are my files uploaded to a server?

No. Everything runs locally in your browser using pdf-lib. Your PNG files never leave your device.

Does the PDF preserve PNG transparency?

PNG transparency is preserved when embedding into the PDF. Transparent areas will appear as white on most PDF viewers since PDF pages have a white background by default.

How many PNG images can I combine?

You can combine up to 20 PNG images into a single PDF.

What page size does the PDF use?

Each image is scaled to fit an A4 page (595 × 842 points) while preserving its original aspect ratio.

Can I mix PNG and JPG images?

This tool is optimised for PNG files. For mixed formats including JPG, WebP, and others, use the Image to PDF tool instead.
