Web2PDF is an extremely useful web based service that lets you browse the web using your email address.
Compose a new email message, type the URL of any web page in the body of that message and send it to firstname.lastname@example.org. The service will then fetch the corresponding web page on its own servers and will send it back it you as a PDF attachment – all this takes no more than a few seconds.
I have tried this service will several web pages, including ones that have complex layouts, and the conversion was more or less perfect in all cases (see examples here and here). The converted PDFs not only retain the layout but also the hyperlinks and thus you may fetch other internal pages as well using email itself.
Such a service may come handy in quite a few situations like when you have access to email but general web access is restricted. Or when you are surfing the web on an old mobile phone with a pathetic browser – in that case, the built-in PDF reader may be a better option for reading web articles.
