Mobile preview pdf

I didn"t know which plug-in I used before, so I previewed it with the iframe tag type= "application/pdf". App flicker occurs when the
file is large. Without considering changing the image type again, is there any plug-in for app Preview pdf that is more useful?
the pdf.js is a little big, and I think a lot of people have experienced flashbacks. If there is no more suitable plug-in, is there any other solution to this problem?
