Action extensions, part of extensibility, let apps share their functionality with other apps installed on your iPhone or iPad. For example, you can use a 1Password action extension to log in to your Twitter account from inside Tweetbot. You can use a Bing action extension to translate a web page inside Safari. You can use a PDF Expert extension to turn an article into a document. You can even use an app like Workflow to create your own, custom action extensions. All you have to do is turn them on, set them up the way you like, and then put them to use!

Action extensions will show up in Share sheet of any app that supports them. However, the Share sheet will only show action extensions that support the app's content type. For example, 1Password and Things will show up in Safari but not in the Photos app. Since most action extensions are available in Safari, that's the best place to enable, disable, or reorder them.
