How to turn JPG or PNG images into a PDF on iPhone
You don't need special software to turn JPG or PNG images into a PDF on iPhone. FernPDF runs entirely in Safari on iOS: open the tool, drop your file, download the result. Photos of IDs, receipts and forms stay on your device, the safest way to PDF anything personal.
Files from iCloud Drive or the Files app open directly in Safari, and processing happens on the phone itself: no app to install, and nothing uses your data plan to upload.
