On iPhone
- Open the webpage in Safari. Press and release Side+Volume Up together on a Face ID iPhone, or Side+Home on a Home-button model.
- Open the screenshot editor; tap the thumbnail if your settings show one. Choose Full Page and inspect the long preview.
- Use the save control to choose Save to Photos for an image, or Save PDF to Files and select a location.
Apple’s current iPhone instructions describe both destinations. Controls vary with iOS version and settings; Full Page is not available for every screen.
On Mac
Do not look for the iPhone Full Page control in the same place on desktop Safari. For a document, choose File → Print → PDF → Save as PDF, following Apple’s Mac instructions. This is a print-layout PDF, not a continuous image.
For a public webpage image, try full-page capture. For printable output, use Website to PDF.
