I remember there was a service some years ago that made clean PDFs -- but the name escapes me now. I was hoping things must have matured even more now -- but the websites have become even more cluttered and loaded with popups and cookie banners instead.
Disclaimer: I asked the same question an year ago as well here : https://news.ycombinator.com/item?id=38403624
I believe Windows can also save to PDF through the print option. Don’t know about Linux.
Some web pages will have print-specific CSS that will format nicely without ads, others won’t. I’ve seen some that actively resist printing.
