How to Adjust Photo Size on Mac

Resizing images can be a daunting task, especially when dealing with large files that take up too much space and slow down your website's loading speed. In this tutorial, we'll show you how to easily adjust the size of your photos on a Mac using Preview and other photo editing tools.

Reducing File Size

Before we dive into resizing, let's talk about reducing file size. You can export your image as a JPEG and manually dial down the quality to reduce its file size. For example, I reduced my 346KB PNG image to 37KB without compromising its quality for web use.

Using Preview

To resize an image on your Mac using Preview, follow these steps:

1. Open your image in Preview.

2. Choose 'JPEG' as your file type and set the quality manually to reduce the size further.

3. Use the 'Save for Web' option if you're using Photoshop or another editor that has this feature.

Resizing Using Crop and Resize

Another way to resize an image is by cropping and adjusting its dimensions. Here's how:

1. Start with a bigger image, as it will give you more flexibility when resizing.

2. Use the selection tool to select and crop the height to the required dimension.

3. Adjust the width accordingly, making sure to constrain proportions.

Using Photoshop or Other Editors

If you're using Photoshop or another editor, follow these steps:

1. Open your file and go to 'Tools' > 'Adjust Size'.

2. Enter the desired dimensions and constrain proportions to ensure a smooth resize.

3. Browse and open your file, then click on 'Tools' > 'Adjust Size'.

Understanding Resizing

When someone says they need to resize a photo, it means they want to change its dimensions to fit a specific space or requirement. This can be done using various photo editing tools, including Preview, Photoshop, Pixlr, MS Paint, and more.

In this tutorial, we've shown you how to easily adjust the size of your photos on a Mac, from reducing file size to cropping and resizing. Whether you're looking to optimize images for web use or fit them into a specific space, these tips will help you achieve your goals quickly and efficiently.

Resizing photos can be a time-consuming task, but with the right tools and techniques, it's easier than ever. By following this tutorial, you'll be able to resize your images like a pro and make sure they load quickly on your website or social media platform.
