Frequently asked questions
What happens to PNG transparency?
Transparent pixels are flattened to white in the PDF, since most PDF viewers and printers expect opaque page backgrounds.
Do you keep image quality?
PNG is a lossless format. We encode it into the PDF without recompression, so what you see is exactly what you uploaded.
How big can the PNGs be?
Up to your browser's memory. We have tested with 8K-resolution screenshots without issues.
