Mac computers offer a wide range of image editing tools that make it easy to crop and adjust photos to your liking. Post-processing is a vital step in photography; no matter how carefully you compose a shot, fine-tuning is often necessary afterward. Beyond color correction and exposure adjustments, even simple tasks like resizing or cropping an image usually require some level of post-production.

What Is Resizing?
Resizing an image can mean different things. You might want to adjust its physical dimensions by cropping or enlarging it, or you may simply need to reduce the file size without altering the aspect ratio or field of view. In the latter case, lowering the image resolution is the best approach, especially since many social media platforms restrict large file uploads.
Reducing Size on Mac Using the Preview App
Mac’s built-in Preview app can be used for various purposes, including reducing image size. Let’s walk through the process step-by-step.
Step 1: Open the Image with Preview
The first step is to open the image with Preview. To do this, right-click the image you want to resize and select Open With > Preview. This will open your image in the Preview app. You’ll see the image displayed in the Preview window, ready to work on it.
Step 2: Select the Adjust Size Tool
Once your image is open in Preview, go to the menu bar at the top of the screen. Click on Tools and then select Adjust Size. This will open a new window where you can change the dimensions and resolution of your image.
Step 3: Enter the Image Dimensions
You’ll see different options in the Adjust Size window. In this window, you can alter the width and height of your image.
Step 4: Set the Resolution
Next, you’ll need to decide on the resolution, which is measured in pixels per inch (ppi). A higher resolution will result in a higher quality image, but it will also increase the file size. For most web and email uses, a resolution of 72 ppi is sufficient.
Step 5: Save Changes and the Image
Once you’re satisfied with your image’s new size and resolution, click OK to close the Adjust Size window. Then, go to File in the menu bar and click Save to save your changes. Note that this will overwrite your original image, so if you want to keep the original size, save a copy before resizing.
