It can't embed PDFs and there doesn't seem to be a solution in sight, because they want to keep their software stack working in the browser. It supports embedding SVGs, but converting PDF to SVG never works well, so the only reliable option is to render the PDF to high-DPI PNG. The font subsetting seems to be suboptimal. I had small documents that were a megabyte when they should have been a few kilobytes. This however can be fixed with PDF tools.
