iPhone guides: scan documents, make PDFs and protect your ID copies
Your iPhone already has most of what a document needs: a scanner in Files and Notes, a PDF maker in Preview, markup in Photos and locks behind Face ID. These guides show where each one is and what it cannot do, with nothing extra to install.
To get a paper document into the phone, scan it with Files or Notes or convert a photo you already took to PDF. Before a copy leaves the phone, blur the numbers that should not travel or add a watermark that names who it is for.
To keep copies private, lock document photos with a password or Face ID. And if you are wondering what can live in Apple Wallet, read which IDs Apple Wallet accepts, country by country and whether a digital driver's license can be saved as a PDF.
