This article explains how to crop videos on iPhone, iPod touch, and iPad devices running iOS 11 or later. Instructions include how to use the built-in cropping feature on iOS devices, as well as how to use a third-party cropping app, which is required to crop videos on any device running iOS 12 or earlier.

In iOS 13 for iPhone and iPadOS, Apple introduced built-in video cropping to its mobile devices. The process is similar to cropping photos in previous versions of the operating system. If you're used to doing that, the new feature is easy to pick up.

Navigate to the video you want to trim and select it.

Select the Crop button. This button is indicated by a square with circular arrows in the menu at the bottom of the screen.
