How to Take a Full Page Screenshot on iPhone
Ever try to take a screenshot on your iPhone, then become frustrated that you can only fit so much of the page onto your screen? If you’d like to save everything on the page, not just what’s on your screen, you can try taking a full page screenshot. With the latest version of iOS, you can capture an entire PDF, email, webpage, and more in Apple’s first party apps.
First, press the side button and volume up button at the same time to take a screenshot. Tap the preview of your screenshot that appears in the bottom left corner of the screen. Tap the Full Page option. Then select Done and Save to Photos. When you view the screenshot in your camera roll later, you’ll see you’ve saved a photo of the entire page, not just the portion of it that was on your screen when you took the screenshot.
