Complete guide
How to use PNG to PDF Converter
PNG to PDF is essential for combining screenshots into a single document, creating a photo PDF from high-quality graphics, or packaging design mockups for client review. PNG files preserve transparency and lossless quality, making them ideal for graphics that need to look sharp in a PDF.
Note: PDF does not support transparency natively. Transparent areas in PNG files become white in the PDF output. If your PNGs have transparent backgrounds and you need them to show on a coloured page, flatten the transparency in an image editor before converting.
All processing runs in your browser - no server upload, no file size quotas, and complete privacy for sensitive images.
How to use it
Upload your PNG files, click Convert, and download the PDF. For multi-page output, upload all PNGs in one session. Pages appear in the upload order.
Best practices
For design mockups, export PNGs at 2x or 3x resolution for a sharper PDF. Flatten transparent backgrounds to white before converting if you need a clean look. For small file sizes, compress PNGs first.
Quick checklist
- Upload all PNGs in one session for a multi-page PDF.
- Transparent areas will become white - flatten transparency first if needed.
- Use high-resolution PNGs (300 DPI equivalent) for print-quality output.
- Compress oversized PNGs using PNG Compress before converting for a smaller PDF.
Answers
PNG to PDF Converter FAQs
Does transparent PNG background become white in the PDF?
Yes. PDF does not support transparency. Transparent pixels in PNG become white in the PDF output. Flatten the transparency in an image editor first if you need a different background colour.
Can I combine multiple PNGs into one PDF?
Yes. Select multiple PNG files on upload. Each becomes a page in the PDF, in the order you selected them.
Is my image uploaded to a server?
No. PNG to PDF runs entirely in your browser. Your files never leave your device.
Can I convert screenshots to PDF?
Yes - this is one of the most common uses. Screenshots are PNG by default on most operating systems. Upload them and convert to a multi-page PDF document.
What is the difference between PNG to PDF and Image to PDF?
PNG to PDF accepts only PNG files and is optimised for that use case. Image to PDF accepts JPG, PNG, WEBP, BMP, and SVG - use it when you have mixed image formats to combine.
