Resizing images is a common task that can be performed using various tools available on macOS. While macOS does not have a direct command called "Image.resize," it offers several built-in utilities and third-party applications that allow users to resize images effectively. This article will guide you through using these tools to resize images on your Apple device.

Using Preview to Resize Images

Preview is a versatile application that comes pre-installed on all macOS devices. It allows users to view and edit images, including resizing them.

Steps to Resize an Image Using Preview:

1. Open the image you want to resize in Preview.
2. Go to the menu bar and click on Tools.
3. Select Adjust Size... from the dropdown menu.
4. In the dialog box that appears, you can set the desired width and height. You can also choose to scale the image proportionally by checking the "Scale proportionally" option.
5. Click OK to apply the changes.
6. Save the resized image by clicking File > Save.

Using Automator for Batch Resizing

Automator is another powerful tool on macOS that allows you to automate repetitive tasks, including batch resizing of images.

Steps to Batch Resize Images Using Automator:

1. Open Automator from the Applications folder.
2. Choose New Document and select Workflow.
3. In the Library pane, select Photos and drag the Get Specified Finder Items action to the workflow area.
4. Click Add and select the images you want to resize.
5. Drag the Scale Images action from the Library pane to the workflow area.
6. Enter the desired pixel width. Automator will scale the height proportionally.
7. Save the workflow and run it to resize your images.

Using Terminal with Sips Command

For users comfortable with command-line interfaces, the sips (Scriptable Image Processing System) command in Terminal provides a way to resize images.

Example of Resizing an Image Using Terminal:

1. Open Terminal from the Applications > Utilities folder.

2. Use the following command to resize an image:

   sips --resampleWidth 800 /path/to/image.jpg

   Replace /path/to/image.jpg with the actual path to your image and 800 with the desired width in pixels.

3. The resized image will overwrite the original. To save it as a new file, use the --out option:

   sips --resampleWidth 800 /path/to/image.jpg --out /path/to/resized_image.jpg

Third-Party Applications

If you require more advanced features, consider using third-party applications like Adobe Photoshop, GIMP, or Pixelmator, which offer extensive image editing capabilities, including resizing.
