iPhone secret features: Save as PDF

Has anybody figured out the "screenshot -> Full Page" save to PDF option when the page is too long and gets cut off? I like to save MSDN pages and the result would be great, bt there's an arbitrary height cutoff apparently that makes the feature unusable.

It’s crazy that this feature is so hidden, leave it to Apple to obscure such useful functions.

I spent a long time trying to Print to PDF on iOS - my previous solution was sending URLs to the Books app. It creates a PDF in Books that I can then share.

These days (or always, I don’t know) you can also select print and then tap print in the top right corner without selecting a printer. That will also open the new share menu with the option to save to files.

Why would you keep something like this secret?

I once had to show a JD how to print to PDF on a laptop, and they acted like I'd just turned water into weed ticture.

It's extremely hard to find this feature. I sometimes want to use this but I can't find it without googling. Bad design.
