Since the launch of the iPhone, its camera has advanced to the point where it can capture high-resolution photos that rival many DSLR cameras.
The downside is that these stunning images often come with huge file sizes, making them difficult to share via email or text. They also quickly consume storage space on your device. That’s why knowing how to resize images can be incredibly useful for saving space and making photo sharing easier.

Reduce Image Size Before Taking Photos
The simplest way to prevent oversized photos from filling up your iPhone storage is to adjust your camera settings. This way, your images take up less space without sacrificing quality.
Here’s how to do it:
- Open your iPhone’s Settings.
- Tap Camera → Formats.
- Select High Efficiency to save images in smaller file sizes while keeping quality intact.
- For even more savings, go to Pro Default and choose HEIF Max (up to 48 MP). This option keeps photos sharp but limits their size to around 5 MB each.
Easy Cropping Options You Should Know for iPhone
Did you know you can resize images on your iPhone without installing any third-party apps? The built-in Photos app makes it easy to crop and adjust orientation for sharing on social media or sending to friends and family. However, this method won’t actually reduce the file size.
If you want smaller file sizes, you can use a couple of other built-in options. The Shortcuts app allows you to resize images without cropping, while Apple Mail lets you send photos to yourself at a lower resolution, automatically shrinking the file size.
Here are three simple ways to resize photos on your iPhone:
- Use the Photos app to crop and adjust dimensions (does not reduce file size).
- Send photos via Mail to yourself at a smaller resolution.
- Create a custom shortcut with the Shortcuts app to resize images without cropping.
Step-by-Step Guide: Resizing Images on iPhone in Photos
To resize a photo using the Photos app, you’ll need to crop the image to make it smaller. This method is handy if you already plan to crop the picture, since it saves you from using additional tools.
Keep in mind that cropping in Photos does not reduce file size or free up storage, because your iPhone keeps the original image in case you want to revert later. If your goal is to shrink the overall file size, you’ll need to use one of the other methods mentioned below.
How to Crop and Resize a Photo in the Photos App
- Open the Photos app and select the image you want to crop.
- Tap Edit.
- Tap the Crop tool.
- Drag the corners of the photo to adjust the borders, or tap the aspect ratio icon to crop to a standard format.
- Move the image with your finger until it fits the chosen aspect ratio.
- Tap Done when you’re satisfied with the result.
Resize Photos on iPhone Using Mail (Without Cropping)
If you only need to resize an image occasionally, one of the simplest methods is to send it to yourself via Mail. This gives you the option to compress the image and reduce its file size. Once resized, you can easily share it on social media, send it in a text, or forward it by email.
How to Resize a Photo Using Mail
- Open the Photos app and select the image you want to resize.
- Tap the Share icon at the bottom of the screen.
- Choose the Mail app.
- Enter your own email address in the recipient field.
- Tap the Send arrow.
- From the pop-up menu, select the file size you prefer.
- The photo will be sent automatically. Once you receive it in your inbox, you can save it back to your photo library or forward it to someone else.
Easily Resize Photos on iPhone Using the Shortcuts App
The Shortcuts app on iPhone makes it easy to quickly resize photos without the need for third-party tools. This method is especially useful if you resize images frequently and find the Mail method too inconvenient. Once you set it up, you can reuse the shortcut anytime you need.
Available on iPhones and iPads running iOS 11 or later, Shortcuts is preinstalled by default. Using it to resize photos will adjust their dimensions, helping reduce file size and making images easier to share.
How to Create a Resize Shortcut
- Open the Shortcuts app (search for it if you don’t see it on your home screen).
- Tap the + icon to create a new shortcut.
- Tap Add Action.
- In the search bar, type resize and select Resize Image.
- Set your default parameters (enter either a width or height, and let the other dimension adjust automatically to preserve aspect ratio).
- Tap the shortcut’s name at the top to rename it if desired.
- Return to the Shortcuts home screen, long-press your new shortcut, select Details, and toggle on Show in Share Sheet.
How to Use the Resize Shortcut
- Open the Photos app and select the image you want to resize.
- Tap the Share icon.
- Scroll down and choose your resize shortcut.
- Your image will be resized automatically.
With this shortcut in place, resizing photos becomes fast and effortless, perfect for anyone who takes a lot of pictures. Just keep in mind that frequent resizing can create multiple versions of the same image, which may clutter your storage over time.
Image Resizing for Web on iOS
Resizing images for web use on iOS devices presents unique challenges, primarily due to the diverse range of device resolutions and display sizes. The key is to create responsive images that look good on any device, from the smallest iPhone screens to the largest iPad tablets.
To achieve this, we need to utilize responsive design techniques, such as creating multiple image versions for different screen resolutions. This method, often called srcset in HTML, allows the browser to select the most appropriate image size based on the user’s device, ensuring faster loading times and improved performance.
Additionally, you can consider using third party tools like Cloudinary to dynamically resize images for you. Cloudinary can automatically resize images based on the viewer’s device, whether iOS, PC, or mobile. By integrating Cloudinary’s cloud-based image management, you can automate the creation of multiple image versions, significantly simplifying the process of preparing images for the web on iOS.
Integrating Cloudinary for Advanced Image Management
At its core, Cloudinary is a comprehensive media management platform designed to help developers effortlessly handle a myriad of tasks, ranging from image and video uploads to highly advanced transformations.
One of the platform’s standout features is its capability to dynamically resize images, ensuring that your iOS application delivers optimal performance and visually engaging content across all devices.
Let’s put this into a real-world context. Suppose you’re developing an e-commerce app for iOS. Your product pages will likely feature multiple images, requiring different sizes for thumbnails, zoomed views, and more.
Manually creating and managing these variants is time-consuming and error-prone. With Cloudinary, you’d simply upload the original high-resolution image and then use Cloudinary’s URL-based API to dynamically request the exact size needed at runtime. For example:
This URL effortlessly tells Cloudinary to fetch the product-image.jpg, resize it to 300×400 pixels, and fill the given dimensions, ensuring the image is never distorted. All of this happens on the fly, with the processed image delivered through a fast content delivery network (CDN), enhancing your app’s performance worldwide.
