Have you ever caught yourself asking, "Can I resize a photo on my iPhone?” Well, you're in luck because the answer is definitely yes! Knowing how to resize images is super useful for any iPhone user!

In this guide, we’ll dive into three expert methods to help you scale your photos just right: using the handy Photos app, exploring some robust third-party applications, and leveraging advanced AI technology with Luminar Neo. So grab your iPhone, and let’s get started on turning good photos into perfect ones with a few simple photo adjustments!

What It Means to Resize Images

Cropping a photo of a giraffe | Skylum How-toThink about a favorite photo that isn't quite the right size for what you need. Maybe it's too big to send in a quick message or too small to look good as your new profile picture. That's where resizing comes in handy.

Resizing lets you adjust the size of your image. You can make it larger, which we call upscaling, to fill space nicely on your website or ensure it doesn’t look blurry on a bigger screen. Or, you can make it smaller, known as downscaling, which is perfect when you need to save some space on your phone or speed up your website's loading time.

Although it's a bit different, cropping—cutting out parts of the image to shift the focus—is another way to resize. It helps you frame your photo exactly how you want it!
