With a fancy bit of integration, iOS can take a full-page, scrolling screenshot. Using a Mac’s built-in screenshot tool, still images are limited to what’s visible on the screen at time of capture, whether the whole desktop, a selected portion, or a particular window.

Using Safari on iPhone and iPad, you can take a screenshot of a full webpage — a single image that shows the entire vertical height of a page, not just what’s plainly visible without scrolling.

To do so on Mac requires a third-party application, such as Shottr.

Capture a full page screenshot of a webpage on iPhone and iPad

Scrolling Screenshot on Mobile

On iPhone or iPad, open a webpage in Safari and trigger a screenshot in the normal fashion, as I described in Mobile Screenshots. Immediately tap on the screenshot thumbnail that appears in the bottom-left corner.

Then, choose the Full Page toggle at the top. This will display the full height of the webpage, which you can scroll by dragging the preview on the right.

If you want to crop the image and only save a portion of the height or width of the page, tap the Crop tool  at the top and drag the handles to adjust. As you crop, removed sections disappear from the preview. If you remove too much, tap Reset and start over or tap Cancel to escape.

You can use all the other usual annotation tools to mark up the image as you wish. When you’ve got the scrolling screenshot you want, tap Done to save or copy it or tap the Share button  for access to all other sharing actions.

(Note that normally mobile screenshots will automatically save to Photos. However, in markup mode, saving to Photos is only available by first tapping Done.)

Use Shottr to capture a scrolling screenshot on Mac

Scrolling Capture on Mac

Shottr exists as a menubar item. (It requires Screen Recording and Accessibility permissions on first run.) In its menu, select Scrolling Capture.

Then, use the crosshairs to select a portion of the current window. Shottr will automatically scroll the window down to the maximum height specified in its settings.

Afterward, the app will show the resulting image, which you can further crop or annotate. You can also set it to copy the screenshot to the clipboard and/or save it to a specified folder.

Additionally, these and other actions are available after viewing/annotating the image, using the various buttons on the toolbar.

It’s cool that scrolling screenshot functionality is built into iOS. Though macOS currently lacks a first-party solution, Apple supports developers to fill in the gap.

Shottr may be the only free app that does so. However, if you use it much, it’s worth supporting Electric Endeavors by paying the $8 license fee.
