Zoom in part of a photo on iPhone iPad

Zooming photos in or out is one of the most used Photoshop skills. You can select and enlarge any specific section or area of a picture and create a magnifying glass or magnifier lens effect using Photoshop on your PC or Mac. If you don’t have access to a computer or not a Photoshop user, you may want to know if it’s possible to do so on a mobile device, your Android phone or tablet, iPhone or iPad. You are lucky if you are using a recent iPhone or iPad model. Because there is a new iOS Markup feature provides a set of useful tools you can use to edit images, screenshots, PDF and other documents on iPhone and iPad. Magnifier is one of the markup tools you can use to enlarge or zoom in any specific part of an image on iOS device. Note that this is different from resizing the whole picture. See details below.
