Resize a photo on iPhone or iPad — step-by-step guide

Julia Moore
Apple pays considerable attention to the quality of photos. This is the reason why snapshots can be up to several megabytes. Sometimes it becomes torture to send a photo to a friend or upload it on Instagram. Fans of shooting everything often face a lack of memory. Especially if they then edit them in several variants. It takes even more memory volume. In this article, we'll tell you about methods that help you to cope with such problems.

Resize without cropping

Apple developers added Shortcuts to reduce the size of pics. Therefore, users don't need to search for a third-party app in App Store.

Shortcuts are available on iPhone and iPad with iOS 11 and later.

Here is an instruction on how to use this pre-installed app on devices with iOS 15. The interface may look a bit different if you have one of the previous versions, but steps have to be the same. If you have any difficulties with creating a shortcut, write to us in the comments, we'll try to help you.

01. Open Shortcuts.

02. Tap a plus icon in the upper right corner.

03. Type a title in the Shortcut Name field. You can come up with any name.


04. Hit Done.

05. Then, tap Add Action.

06. Type Get Images from Input in the search bar.

07. Choose Get Images from Input. The first action is ready.

08. Tap a blue button with parameters in the top-right corner.

09. Move the slider to the right next to Show in Share Sheet.

10. Hit Done.

11. Tap the search bar and type there Resize Image.

12. Choose the action.

You can set the height and width right away during creating a shortcut, or choose Ask Each Time to manually adjust the resolution on each photo. We advise you to set up the required parameters while shortcut creating so that you won't waste time on that every time.

13. The width is set to 640 by default. Tap the width parameter to change it to 1080. It's the standard value for Instagram Stories and posts.

14. Leave Auto Height so that the images don't shrink or stretch. Then the device itself will select the appropriate value height to maintain the proportions. 

15. Hit Done.

16. Next, tap the search bar again and type Convert Image.

17. Choose the action. This step allows you to change the original format of the picture to any other.

18. If you want to get images in another format, tap JPEG to choose the appropriate one.

19. The last thing that you have to do is to add Save to Photo Album action. For that, tap the search bar one more time and type it there. 

20. Hit the Shortcut action

21. The resized image version will be saved in Camera Roll in Recents. If you want to save photos to a specific folder, you can select the appropriate one by tapping Recents.

22. Tap the cross icon to save the shortcut.

23. Let's check how Shortcut will work. Open any of your photos. Hit the share icon in the bottom left corner.

24. Scroll down till you see Resize Photo. Choose this button. When a resized photo is ready, you'll see a check mark in the top part of the screen.

25. To exit the menu, tap the cross icon in the upper right corner.

26. Done! The result is saved to Recents. Now, the picture in the reduced version weighs 246 KB. The original size was 6.3 MB.

The original photo remains unchanged. A resized version of the snapshot is added to the Camera Roll. Don't forget to delete the original, if you don't have enough space on your device.

You don't need to repeat all the steps every time. All that you have to do is tapping Resize Photo under the snapshot.

Resize photos via Mail

If resizing photos via Shortcuts seems too challenging to you, we suggest trying to do it using Mail.

The advantage of this method is that you can immediately see the weight of the original image and choose the one to which it will be reduced. Mail will offer you to choose one of 4 options for reducing the weight small, medium, large or original. This method affects both the weight of the image and its resolution.

01. Open Mail.

02. Create a new message by tapping the icon with a pen and paper in the bottom right corner.

03. In the To field add an addressee. You can choose yourself or the person to whom you want to send the photo. 
04. Hit the image icon to attach the file.

05. Tap the arrow icon in the upper right corner to send the message.

06. Select the size that's appropriate for you.

07. To save the sent photo to your phone, go to Sent and find the email with the picture.

08. Tap the attached photo.

09. Hit the share icon.

10. Choose Save Image.

Thus, you will have two identical photos of different weights in your Camera Roll. If your goal is to free up memory in your phone, then don't forget to delete the original version.

Resize photos by cropping

It also happens that you don't like the way the photo looks. For example, it was taken too far from the object, or something got into the frame from the edge that spoils the picture. In this case, you can crop the photo.

One caveat: This method won't increase the free memory of your device, since the original photo doesn't disappear anywhere, although it changes its appearance. But if you want to share a picture via messenger or add it to social networks, then the file will be uploaded with the settings applied, that is, with the changed weight and resolution.

You can crop a photo using the built-in iPhone functions.

01. Open the gallery and select the photo you want to crop. Hit Edit.

02. Tap the crop icon at the bottom of the screen.

03. At the top, select the icon with rectangles near the three dots.

04. Select the aspect ratio. This will allow you to get a horizontal image from a vertical one and vice versa. At the bottom part of the screen, you can see combinations of numbers. The first number is the width. The second one is the height. 

05. If you want to manually crop the photo, then choose Freeform. To crop a picture, you can make it by sliding the edges of the frame, or enlarge the picture by placing two fingers on the screen and bringing them together.

06. To save the result, hit Done.

It's important to know that the original parameters of the photo don't disappear anywhere, and you can always return to them.

  1. To do this, just go back to Settings and tap Edit.
  2. In the lower right corner of the screen, hit Revert.
  3. Confirm Revert to Original.

If your goal was to improve the photo, and cropping didn't help you in this, then try adding filters and working with the colors of the picture.

How to find out the size of a photo

Finding out the size of a photo has become much easier with the release of the iOS 15. Previously, it was necessary to create a Shortcut. Now it can be done in a couple of steps.

  1. Open Camera Roll and select the photo or video.
  2. At the bottom of the screen, tap on the information icon.

Done! Here you will see the weight of the file, its resolution, format, and file source.

You can easily upload pictures in reduced weight and resolution to Instagram or to your website. If you don't have the second one, then create a landing page on the Taplink in just a few minutes. What is its advantage over the site?

  • Landing pages are perfectly displayed on mobile devices.
  • They load instantly due to the optimized page code.
  • You don't need to be a programmer or a designer.

When you upload a photo for a banner or a carousel of images to a landing page, you don't need to bother cropping the pictures. Taplink will compress and optimize the images itself. Start your acquaintance with the Taplink from the main page.

Let’s recap

Not many users of Apple products are aware of all the features of Shortcuts, thanks to which, for example, you can reduce the size of a photo and not download third-party applications.

Now that you know the tricks of using the iPhone's capabilities, the problem of overflowing memory or the inability to upload a picture to Instagram will no longer bother you. If Instagram is still not working correctly, try clearing the cache. But our advice: don't forget to clean the gallery periodically, so as not to clog up your phone with a mountain of identical or already irrelevant pics.
