There is a reason PDF rasterization should be done on the server side and not the client side. It is an incredibly difficult task. It can depend on different factors like the resolution and color space of the target image. It also depends on how complex the PDF input is and the quality of the PDF software. I'm afraid there is no one size fits all answer.
