You can create a PDF on an iPhone from many documents, webpages, photos, and other printable items using the Share and Print controls.
- Open the item and tap Share.
- Choose Print.
- On the print preview, spread two fingers apart on the preview to open it as a PDF.
- Tap Share again.
- Choose Save to Files or another destination.
Some apps provide a direct Create PDF or Export as PDF command, so use that option when it is available.
If the labels on your screen differ slightly, use Settings search or the app’s current menus to find the named feature. Apple sometimes moves controls between iOS releases, so follow the feature name rather than an unrelated setting with similar wording.
