info About this tool
Convert PNG images to PDF documents instantly. PNG files with transparency are composited onto a white background before embedding: making them suitable for printing and formal document use. The image is scaled to fit an A4 page while maintaining its aspect ratio, producing a clean, professional PDF ready to send or archive.

File size: PDF output is typically 2 to 5 times the size of the source PNG due to PDF overhead and JPEG embedding.

Quality: PNG is converted to JPEG at 95% quality internally for PDF embedding. Transparent areas are filled with white.
