The editor in the Photos app is quite feature-rich, but you can’t resize photos. Luckily, you can use a shortcut or a third-party app to resize or reduce photo size on iPhone and iPad. Here’s how.
How to Resize a Photo Using Shortcuts
If you need to reduce a photo’s resolution or file size, look no further than the Shortcuts app. Shortcuts is Apple’s built-in automation tool that helps you create your own tools and simplify multi-step processes that you perform frequently.
Using Shortcuts, you can create simple automations that follow predefined steps. In this guide, we’ll create a shortcut that can take single or multiple photos, resize them based on your input, and save the resulting output back to the Photos app.
To get started, open the Shortcuts app on your iPhone or iPad. In the “My Shortcuts” tab, tap the Plus (“+”) button in the top-right corner to create a new shortcut.
Tap the “Add Action” button.
Search for and then add the “Resize Image” action.
Now it’s time to customize this action. Tap the “Image” button.
In the pop-up, choose the “Shortcut Input” option. This means that the shortcut will resize any image that you send to it (It’s useful for sending multiple images using the Share menu in the Photos app.).
Next, it’s time to decide the resulting width and height. By default, the shortcut will resize the image to 640 pixels wide with auto height.
You can tap the “640” button to change the default, or you can switch to the “Ask Each Time” option. This would be our recommendation, as it gives you the freedom to change the resolution without duplicating the shortcut.
It’s best to leave the “Auto Height” option as the default. Next, tap the Plus(+) button to add the next action.
Search for and then add the “Save to Photo Album” action.
By default, this action will save the resized image to the “Recents” album. If you want, you can tap the “Recents” button to change the album.
The shortcut is now created. Tap the “Menu” button to customize it.
Here, give the shortcut a name at the top, and then be sure to enable the “Show in Share Sheet” option.
Tap the “Done” button at the top to save the customization.
On the shortcut screen, tap the “Done” button again to save the shortcut.
You’re all done in the Shortcuts app. Next, launch Photos on your iPhone or iPad.
In Photos, select a photo (or the photos) that you want to resize and tap the “Share” button (which looks like a rounded square with an arrow pointing upward from it).
Scroll down and select the shortcut that we just created (in our example, it’s called “Resize Images,” but you might have named it something different in the Shortcuts app above).
Enter the desired image width in pixels and tap the “Done” button.
After a moment, the shortcut will resize the image (or images), and you’ll find it (or them) saved in the “Recents” album in the Photos app.
