Frequently asked questions
Is PNG always better than JPG for PDFs?+
PNG is better for text-heavy or diagram-based PDFs. For photo-heavy PDFs, JPG produces smaller files with acceptable quality.
Will transparent backgrounds be preserved?+
Pages with vector transparency render correctly in PNG with alpha channel. Most PDF pages have a white background.
Can I use PNG output in image processing scripts?+
Yes — PNG is widely supported by Python Pillow, ImageMagick, Node.js Sharp, and all standard image libraries.
