Windows 10 finally lets you “print” documents to PDF, which means that you no longer need to install a third-party app to save a web page or document for use offline. You can now simply select PDF as a printing output option.

To Print to PDF in Windows 10:

1. Open up your document e.g. in a text editor like Microsoft Word (this actually works from any program that lets you print, not just Word, and not just with a text document).
2. Click File > Print.
3. Under Printer or Destination, choose Print as a PDF.
