ClipExt is a free iPhone app developed by Sanwa Heating Inc. It falls under the category of Utilities & Tools and offers a convenient way to cut and save parts of webpages as images.

With ClipExt, you can easily save images from webpages along with their corresponding titles and URLs. When using the extension from Safari, you can select and cut out specific sections of the current webpage. These images, along with their titles and URLs, can then be sent to other message extensions and social networking sites, as well as saved within the app.

One of the useful features of ClipExt is the ability to lock the aspect ratio of the images you cut. By default, the ratio is set to 16:9, but you can also choose between 1:1 and a free ratio. Additionally, there is a mode that allows you to send only the image while copying the title and URL separately. This is particularly helpful when certain extensions do not support the automatic entry of titles and images when sending URLs.

It is important to note that when using images and content from others, it is necessary to respect the boundaries of fair use and citation.
