There are times when you need to highlight or enlarge a part of the image to see better detail. This is how you can use the tools on the iPhone and iPad to enlarge some photos.
Apple has integrated the Magnifier feature in the Markup tool. If you are not familiar, Markup tools are available in many locations throughout iOS and iPadOS. For example, you can access it when you edit images or PDFs in the File application, as well as when you open an attachment in the Mail application.
To zoom in on something currently on your screen, you can use the screenshot editing feature on your iPhone and iPad. Take a screenshot on your device by pressing the Side key and the Volume Down key together. If you are using an older device, press the Side button and the Home button together.
Next, tap on the “Screenshot Preview” button in the lower left corner.
Here, tap the “+” button. You will find the “Magnifier” option in the menu that appears.
The process is a bit more complicated when it comes to the Photos application. Open the image you want to enlarge in the “Photos” application then tap the “Edit” button from the top right corner.
Tap the three dot Menu button found in the upper right corner of the screen.
From the sharing sheet, select the “Markup” option.
Now, tap the “+” button and select the “Magnifier” option.
Now you will see a magnifying circle in the center of the image. You can drag it to any part of the photo that you want to zoom in on.
The blue dot will help you increase and decrease the size of the magnifying glass. Tap and slide in or out to resize.
You can use the Green dot to change the zoom level. Swipe right to zoom in and swipe left to zoom out.
After finishing editing, tap the “Finish” button from the top of the screen.
From the image editing screen, tap the “Finish” button from the bottom of the screen.
Now you will see the edited photo in the Photo gallery. You can share enlarged photos using the email or messaging application.
