In a world constantly on the go, our iPhones have become more than just a device for making calls. They’re our cameras, our photo albums, and our portals to sharing moments with the world.

Whether you’re a professional photographer who needs to quickly edit photos on the fly or someone who just wants to tweak a picture before posting it on social media, knowing how to manipulate images on your iPhone is an invaluable skill. Plus, it can save you time and the hassle of transferring photos to a computer for editing. This guide will walk you through the steps to resize, compress, and crop your images, making your photos look their best no matter where they’re displayed.

Step by Step Tutorial on How to Resize, Compress, and Crop Images on Your iPhone

Before we dive into the step-by-step tutorial, it’s important to note that this process will allow you to adjust the dimensions of your photos, decrease file sizes for easier sharing, and remove unwanted elements or reframe your images for a better composition.

Step 1: Open the Photos app and select the image you want to edit.

Once you’ve found the image, tap to view it, and then click on the Edit button in the top right corner of the screen.

This step is pretty straightforward. The Photos app is your hub for all things related to images on your iPhone. It’s where you’ll find every picture you’ve taken or saved onto your device. The Edit button is your gateway to tweaking those images.

Step 2: If cropping, use the crop tool; for resizing and compressing, use third-party apps.

In the editing menu, you’ll see an array of tools at the bottom. Choose the crop icon to adjust the frame of your photo, or download apps like Image Size or Compress Photos to resize and compress.

Cropping is a built-in feature of the Photos app, and it’s incredibly user-friendly. Just drag the corners or sides of the image to adjust the frame. For resizing and compressing, the App Store has several great options that integrate seamlessly with your Photos app.

Additional Information

While the above steps offer a quick way to resize, compress, and crop images on your iPhone, there are a few more things to keep in mind. For starters, always make sure to duplicate your image before making any edits. This way, you’ll have a backup in case something goes wrong or if you’re not happy with the results.

Also, remember that the quality of your photo can be affected by how much you compress it. If you’re planning to print the image or use it for professional purposes, it’s best to compress it as little as possible to maintain the highest quality. Conversely, if you’re just sharing an image on social media, a higher level of compression might be fine since it won’t be viewed on a large screen.

Lastly, while cropping can help improve the composition of your photo, try not to crop too much. Over-cropping can lead to a loss of important details in the image and can affect its resolution.


  1. Open the Photos app and select the image.
  2. Tap the edit button.
  3. Use the crop tool or third-party apps for resizing and compressing.
  4. Save the changes.
