Everything that can be printed from an iPhone can also be saved as a PDF. […]
The function is simple, practical and is often overlooked: the possibility to save any document as a PDF.
Open a document and select the Print command (1). The overview shows the print settings including preview (2). To create a PDF instead, spread it over the preview with two fingers-just as if you were zooming in on a photo. The document is immediately displayed as a PDF (3). Use the Share menu at the top right to save it or circulate it directly.
