Markup and Full-Page Screenshots
The screenshot interface in iOS 13 gains a few really slick improvements, which most notably include the ability to now take full-page screenshots in supported apps.
For example, in Safari, instead of just taking a shot of what you can see on the screen, you can tap a “Full Page” option at the top of the screenshot UI to capture that entire web page, including all of the parts that are out of view. When in full screen mode, a thumbnail of the entire long page appears on the right, with the ability to scroll up and down the page.
This also works in at least some other apps like Mail that often have content out of view, but it’s not quite as universal as you’d expect — for example it doesn’t yet seem to be present in Apple’s own Notes app, and it’s unclear exactly how it will work with third-party apps.
The markup screen tools are also now much more colourful and more detailed, and a trashcan icon appears in the top right corner allowing you to quickly delete a screenshot. When saving a standard screenshot, you can also now choose to save it straight to the iOS 13 Files app instead of just the photo library. On the other hand, the new “Full Page” screenshots can only be saved to PDF files, at least for now.
