How to resize an image using Preview (Mac OS X)
There’s a reason Preview has come preinstalled on all versions of Mac OS X for more than a decade. The built-in application is a fantastic, lightweight tool worth using when looking to make basic photo edits and adjustments in lieu of more intensive software such as iPhoto or Photoshop. Preview is typically set as the default program for viewing images and PDFs, hence it’s usually the first program to open your newly imported images and doesn’t require any external software.
|Step 1: Launch Preview and open your image. Click the Preview icon depicting two photos and a magnifying glass in the main applications folder to launch the program. Once open, click File in the Preview top menu and choose Open from the resulting drop-down menu (second option from the top). Then select your image from its save location and click the Open button in the bottom right-hand corner.|
Step 2: Resize your image. Once the image is opened, click Tools in the Preview top menu and choose Adjust Size from the resulting drop-down menu. A small pop-up window housing various options for resizing and altering your image to your preferred specifications will appear. Choose from the custom presets at the top or select your desired width and height – either by specifying the dimensions in pixels, inches, centimeters, or percentage, among other options – and make sure the “Scale proportionality” and “Resample image” boxes are checked as to maintain the proper proportions when rescaling your image. When finished, click the OK button in the top right-hand corner of the window.
