The editor in the Photos app is quite feature-rich, but you cannot resize photos. Fortunately, you can use shortcut or third party app to resize or reduce photo size on iPhone and iPad. Here̵
Resize a photo with shortcuts
If you want to reduce the resolution or file size of a photo, look no further than the Shortcuts app. Shortcuts is Apple’s built-in automation tool that allows you to create your own tools and simplify the multi-step processes you often perform.
Using shortcuts, you can create simple automations that follow predefined steps. In this guide, we’ll create a shortcut that allows you to take single or multiple photos, resize them based on your input, and save the resulting output back to the Photos app.
To start, 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.
Look for the action “Resize image” and add it.
Now it is time to adjust this promotion. Tap the “Image” button.
In the pop-up, select the option “Input shortcut”. This means that the shortcut will resize any image you send to it (this is useful if you want to send multiple images from the Share menu in the Photos app.).
Next, it is time to determine the resulting width and height. By default, the shortcut will resize the image to 640 pixels wide with automatic height.
You can tap the “640” button to change the default setting, or you can switch to the “Ask every time” option. This would be our recommendation as it gives you the freedom to change the resolution without duplicating the shortcut.
It is best to leave the “Automatic height” option as the default. Then tap the Plus (+) button to add the next action.
Look for the action “Save to photo album” and add it.
By default, this action saves the resized image to the “Recent” album. If you want, you can tap the “Recent” button to change the album.
The shortcut has now been created. Tap the “Menu” button to adjust it.
Name the shortcut here at the top and make sure to enable the “Show in shared sheet” option.
Tap the “Done” button at the top to save the adjustment.
On the shortcut screen, tap the “Done” button again to save the shortcut.
You are all set in the Shortcuts app. Then launch Photos on your iPhone or iPad.
In Photos, select a photo (or the photos) you want to resize and tap the “Share” button (which looks like a rounded square with an arrow pointing up from it).
Scroll down and select the shortcut we just created (in our example, it’s called “Resize Images”, but you may have renamed it in the Shortcuts app above).
Enter the desired image width in pixels and tap the “Done” button.
After a while, the shortcut will resize the image (or images), and you will see that it (or images) is saved in the “Recent” album in the Photos app.
You can now share the resized images to your Mac or use them in any app or website you want.

Resize a photo with a third-party app
While shortcuts can be a great tool for power users (a single shortcut can save you a lot of time if you’re going to resize images often.), Taking the time to create the shortcut can feel like overkill if you just want to. resize a few photos every now and then.
This is where you can find comfort in the free Image Size app. The application has a very simple resizing tool that allows you to change the resolution and also reduce the photo size.
To get started, download the Image Size app from the App Store. After opening the app, tap the Photos button in the top left corner.
The app will ask you to access your photo library. You can give the app access to your entire photo library, or you can select just a few photos.
Once you’ve granted access, go through your library and select the image you want to resize.
In the image preview, tap the “Choose” button.
You will now see the image in the editor. In the “Pixel” section, change the “Width” or “Height” to resize the image (make sure the button in the center, which looks like a chain link, is turned on so that the aspect ratio remains the same).
The app shows the file size of the new, resized image. When you’re happy, tap the Save button (which looks like a downward-pointing arrow with a line below it) in the toolbar at the bottom of the screen.
The app saves the resized image to the “Recent” folder in the Photos app. You can repeat this process to resize as many photos as you want.
On a Mac? You can resize a photo in seconds with the built-in Preview app.
