Right now there in this plugin i don't see a way to reduce the pdf file size. If we can decrease a dpi value then pdf will decrease or anyone has suggestions to reduce the pdf file size

You can achieve something similar by controlling the viewport on the HTML you want to transform.

Thanks for the reply. Right now i am using "viewport" like this

meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no

in my application. I am testing this plugin in ipad pro ios version 13.4 and the pdf i am creating has 28 pages which has file size in 2.4mb. I want to reduce it to below 1mb. How can i achieve this using viewport.

Please help me on this

Sorry for the late response, I think the size depends on the kind of assets in the form of images your are embedding in the PDF.

If those pages contain images ?

consider reducing the images size using compression, or displaying a lower resolution version of the image before transforming can help.

Everything else in the PDF is usually postscript (like) language, that should be very light weight.
