How to Resize a Photo on an iPhone Without Any Third Party App

There are two approaches to resizing a photo on an iPhone without using an app. The first one consists in cropping an image to make it smaller. The second one consists in resizing an image without cropping it. Both can be done natively on an iPhone, without downloading a third-party app.

1. Reducing the size of a photo by cropping it

You can crop your photos using the iPhone’s native photo app. To do so, follow these steps: Step 1: open your photo in the Photos app Step 2: Tap edit button Step 3: Tap Crop button at the bottom of the screen Step 4: Tap Crop box button at the top of the screen Step 5: Select an aspect ratio among the various options (more on that below) Step 6: Select an orientation (Portrait or Landscape) Step 7: Crop the photo Step 8: Tap ‘Done’ button once you’re happy with the cropped photo

 Note that this method doesn’t free up space on your iPhone as the original image is still kept in the iPhone memory in case you changed your mind and wanted to reset the cropping. 

2. Reducing the size of a photo without cropping it

There are 2 easy ways to resize a photo without cropping it on iPhone. Both don’t require you to use any third-party apps as they rely on tools that are part of your iPhone’s default apps.

1. Resizing a photo using the Shortcuts app

This method is available only on iPhone and iPad with iOS 11 and its more recent updates.

One easy way to change the dimensions of your photos is to use the Shortcuts app. It allows you to create custom multi-steps automated tasks. The Shortcuts app is a default app on iOS devices. This means that you don’t need to install it. Below is how you can resize images on your iPhone using the Shortcuts app. Note that 9 out of the 10 steps described below only need to be set up once. That’s why it deserves the name ‘Shortcuts’! 

Creating a photo resizing task using iPhone_s ShortCuts app

 Step 1: find the Shortcuts app on your iPhone by searching for it, or 

Step 2: tap on the Shortcuts app icon 

Step 3: select an Action to be added as a shortcut. In our case we want to resize images so in order to find that predefined task, we search for ‘resize’ in the top search field. 

Step 4: tap on the “Resize image” action 

Step 5: tap on “Add action” 

Step 6: specify the picture size you’d like to resize your original photos to, by either entering a width, an height or both. If you leave the height on “auto”, the aspect ratio of your original photo will be kept. 

Step 7 (optional): you may add other actions if you want the Shortcuts app to do more. For example, you may program Shortcuts to crop your original images, rotate them or flip them. In this tutorial, we’ll focus on our core task which is to resize photos.

By default, the images will be saved into the “recents” album on your iPhone. You may choose a different location by adding a “Save to Photos Album” task to your Shortcut. Then specify where you’d like the resized photos to be saved.

Step 8: in the next step, you’ll be invited to enter a name for the app. Since this command can be called using Siri, make sure you can easily remember it! 

Step 9: in order for the shortcut to be easily accessible in your Photos app, enable the feature Show in Share Sheet

Step 10: Now your shortcut is ready to be used! Go to your Photos library on your iOS device, then tap the Share button. If you scroll down, you’ll be able to see the shortcut you’ve just created. From now onwards, all you need to do for any photo resize task, is to select one or multiple photos, tap the Share button and select Resize my Photos


2. Resizing a photo while sharing it via Mail or Messages

Want to share a photo via email or message? You don’t need to manually resize it. Your iPhone provides you with a convenient way to do so prior to sharing it. While this method doesn’t provide a ton of flexibility, it’s still a solid option to compress photos without cropping them.

Sharing a picture via the Mail app

Step 1: Select a photo to be shared in your iPhone’s camera roll or photo album 

Step 2: Click on the Mail icon 

Step 3: Upon sending the email to the recipient, you will be offered to “reduce the message size by scaling the image to one of [several] sizes”. Mail will give you 4 options: small size, medium size, large size and actual size. All of them, apart from the last one, lead to a reduction of file size and resolution of the image.
