The iPhone Photos app is more than just a photo manager. It is also a pretty powerful image editor. However, unbelievably, it doesn’t allow you to resize the photo.

The Shortcuts app on iPhone is an extraordinary tool that can automate and perform a variety of tasks, even those that are not present in the native app. You can use it to create a custom shortcut that is capable of resizing images, or you can cut to the chase and get a third-party shortcut instead.

Use third-party image resizing shortcuts

Instead of creating your own shortcut to resize photos on iPhone, you can download and use a third-party alternative like Resize Image or Bulk Resize. By default, your iPhone does not support external shortcuts, so you must go to Setting > Shortcuts and turn on the side switch Allow untrusted shortcuts before adding them to your iPhone.

Warning: Third-party shortcuts may not be safe. Add them at your own risk!

Image resizing provides granular control over the entire image resizing process. You can run it through an image’s Share Page and choose from a variety of preset resizing options. Or, you can specify a custom dimension. Once you’re done resizing, you can save the image to the Photos app, share the image with other apps, or copy it to the clipboard.

Image resizing doesn’t limit you in your photo library; it can resize photos on your iPhone from any location such as Files app. However, the shortcut cannot process more than one image at a time.

On the other hand, Bulk Resize allows you to resize multiple images. Run it through the Shortcuts app, specify a width, and the shortcut will save the resized images to your photo library.

Third-party image resizing apps

In addition to keyboard shortcuts, you can use the Image Size, Batch Resize, and Snapseed apps to resize your iPhone images. All three apps are free to use.

Image size

Image Size allows you to add and resize any image in your photo library. You can quickly specify the width and height from the top of the screen in pixels, millimeters, or inches. The preview pane shows the output file size of the image in real time, which is handy if that’s a concern.

Image Size also comes with several image editing tools that allow you to add filters, effects, emojis, text, etc. to your images.

Furthermore, you can go to the app’s Settings screen to configure how the app works. For example, you can set the output format as HEIC or JPEG, specify the output quality, prompt the application to delete the original image after saving, etc.

Batch Resize

As the name implies, Batch Resize is an application (created by the same developer as Image Size) that allows you to process images in batches. Add your photo, specify your size and you’re good to go.

However, unlike Image Size, it doesn’t do anything fancy. Just make sure to visit its Settings screen to determine the output quality and format before you begin.
