python pdfkit: increase font size

Question

I transformed an HTML file into a pdf simply by:

pdfkit.from_file("cpp.html",'cpp.pdf')

Problem is that the font-size is very small.

How to increase the font-size (both of headers and paragraphs) using pdfkit? Obviously I want the headers font to remain bigger than the paragraphs font.

I guess I have to tweak the options, but I can't find how.

Answer 1

In my case manually setting dpi helped.

options = {
    'dpi':96,
}
pdfkit.from_url(url,out_file,options=options)

Answer 2

There's also a zoom option, which solved the problem for me. (Takes a Float)

    options = {
    'zoom': 2,
}
pdfkit.from_url(url,out_file,options=options)
