This workflow is an action extension that allows a URL to be saved as a PDF. This could be a web page, web link on a contact record, etc. The workflow offers two ways to generate the PDF. The first uses the local workflow PDF generation action. The PDF produced by this sometimes has some strange artefacts and truncations, but it generally gets the job done. The second option uses an online service to generate the PDF which I think generally gives better results, but does typically take a bit longer and involves sending the work off your iOS device.
