PNG Transparency in PDF
One of the biggest advantages of PNG is its support for transparency. When you convert png to pdf online with ConvertPDF, the alpha channel is fully preserved. Transparent areas in your PNG remain transparent in the output PDF.
This is essential for:
- Logos and branding — keep backgrounds transparent for professional documents
- Graphics and illustrations — preserve layered designs exactly as created
- Screenshots with rounded corners — maintain clean edges without white boxes
If you prefer a solid background instead, select “White background” or any custom color in the converter settings before clicking Convert.
