This article explains three ways you can take a scrolling screenshot on your iPhone without the need for any third-party apps.

Unlike a regular iPhone screenshot (Volume Up + Power button) which only captures exactly what’s on your phone’s screen, scrolling screenshots go out of bounds. Think of it as a panoramic photo, but for a screenshot. At the time of writing, this feature only works with screenshots taken in the Safari web browser.

Press the volume up button and the power button on your iPhone at the same time (like you would for a normal screenshot).

Tap the screenshot preview that appears in the lower left corner of the screen.
