Changing the Megapixels on an iPhone: A Step-by-Step Guide

Changing the megapixels on an iPhone is not something you can do directly, as the hardware of the camera determines the megapixel count. However, you can choose different resolutions and compression settings that affect the quality and file size of the photos you take, which can give you some control over the end result.

After adjusting these settings, your photos may take up less storage space or have a different level of detail, depending on your choices.


When it comes to capturing memories or snapping that perfect shot, your iPhone’s camera is your best friend. But have you ever wondered if you can change the megapixels on your iPhone camera? Well, you’re not alone! Megapixels matter because they’re related to the resolution of your photos – the higher the megapixels, the higher the resolution and the clearer the picture.

However, you should know that the number of megapixels isn’t the only factor contributing to a great photo – lens quality, sensor size, and image processing also play significant roles. So, why is this important, and who needs to know about it? Whether you’re a photography enthusiast, someone who needs high-resolution photos for work, or just looking to free up some storage space on your device, understanding how to work with the camera settings on your iPhone can be incredibly beneficial.

Step by Step Tutorial on Adjusting Your iPhone’s Camera Settings

Before we dive into the steps, let’s clarify what you’ll achieve by following this guide. While you can’t outright change the megapixel count of your iPhone’s camera, you can adjust settings related to image quality and resolution. These changes can affect how your photos look and how much space they take up on your device.

Step 1: Open the Settings App

First, locate and tap on the “Settings” app on your iPhone’s home screen.
Opening the Settings app is your gateway to customizing various aspects of your iPhone, including the camera settings. Once you’re in the Settings menu, you’ll have access to all sorts of options to tweak your device’s performance and features.

Step 2: Scroll Down and Select ‘Camera’

Navigate through the list and select the “Camera” option to access camera-specific settings.
The Camera settings section is where Apple allows you to change the features related to your camera’s functionality. Here, you can find options for formats, grid lines, video recording quality, and more.

Step 3: Tap on ‘Formats’

Under the Camera settings, tap on ‘Formats’ to change how your photos are captured and stored.
In the Formats section, you can choose between ‘High Efficiency’, which reduces file size for photos and videos, and ‘Most Compatible’, which uses the JPEG format for photos and H.264 for videos. JPEG files are typically larger but more widely supported across different platforms.

Step 4: Adjust ‘Record Video’ and ‘Record Slo-mo’ Settings

Back in the Camera settings menu, select ‘Record Video’ or ‘Record Slo-mo’ to adjust the resolution and frame rate of your video recordings.
Adjusting the video recording settings can help manage storage space as higher resolution and frame rate settings will result in larger files. For instance, recording a video in 4K will consume more space than recording at 1080p.

Step 5: Explore Third-Party Camera Apps

If the native Camera app doesn’t offer the level of control you want, consider downloading a third-party camera app from the App Store.
Many third-party camera apps offer advanced features such as manual focus, exposure settings, and the ability to shoot in RAW format. RAW files contain more image data, allowing for more flexibility when editing photos.


More Storage SpaceBy choosing settings that reduce file size, you can save significant storage space on your iPhone, allowing you to keep more photos and apps.
Tailored Photo QualityAdjusting the settings can help you find the right balance between image quality and file size that suits your needs.
Better Performance for Different NeedsWhether you need high-resolution images for printing or are looking to save data when sharing photos online, you can adjust the settings to optimize performance for your specific use case.


Limited Control Over MegapixelsUnlike a DSLR camera, you can’t directly change the megapixels on an iPhone as it’s tied to the camera’s hardware.
Potential Quality LossReducing the image quality for smaller file sizes can result in a loss of detail, particularly noticeable in large prints or when cropping images.
Complexity for Average UsersTweaking settings for optimal photo quality may be overwhelming for casual users who are not familiar with photography terms and concepts.

Additional Information

When tinkering with your iPhone’s camera settings, it’s important to strike a balance between the quality of your photos and the storage space they consume. Remember, while increasing resolution can lead to clearer images, it also means larger files that can quickly fill up your phone’s memory. Conversely, opting for lower resolution can free up space but at the risk of losing detail in your images.

It’s also worth noting that third-party camera apps can offer a range of features not available in the native Camera app. These apps may allow more in-depth adjustments such as ISO, shutter speed, and white balance, giving you more creative control over your photography. Additionally, shooting in RAW format with these apps can offer greater post-processing flexibility, but again, these files take up more space.

While adjusting these settings won’t change the megapixels of your iPhone camera, they can significantly impact the outcome of your photos and how you manage your device’s storage. So, experiment with different settings to find what works best for your needs and don’t be afraid to try out new apps to expand your photography toolkit.


  1. Open the Settings app on your iPhone.
  2. Scroll down and select ‘Camera’.
  3. Tap on ‘Formats’ to choose between ‘High Efficiency’ and ‘Most Compatible’.
  4. Adjust ‘Record Video’ and ‘Record Slo-mo’ settings to manage resolution and frame rate.
  5. Explore third-party camera apps for additional features and control.
