How to resize an image using GIMP (Windows/Mac OS X)
GIMP, aka GNU Image Manipulation Program, is the Wikipedia of image-editing software: an open-source application that is fueled by a community of volunteers hellbent on making the freemium application a high-quality rival to the many more robust software suites available on the Web. It’s a powerful tool that touts basic and more advanced features alike, albeit with a high learning curve akin to Photoshop and other similar software.
|Step 1: Download and launch GIMP. Head to the GIMP homepage and click the orange Download button in the top right-hand corner to download the executable file. Once finished, run the necessary installation software before launching the program by navigating to your main application or program folder and clicking the GIMP icon (it depicts a dog-like mascot named Wilber). Also, remain wary of any additional add-ons, toolbars, or general malware that may come bundled with the software during the installation process. It can be rather sneaky.|
Step 2: Open your image. Once open, click File in the GIMP top menu and choose Open from the resulting drop-down menu (third option from the top). Then select your image from its save location and click the Open button in the bottom right-hand corner.
Step 3: Resize your image. Once the image is opened, click Image in the GIMP top menu and choose Scale Image from the resulting drop-down menu. A small pop-up window will appear housing various options for resizing and altering your image to your preferred specifications. Select your desired width and height by specifying the dimensions in pixels, inches, or picas, among other options, and then click the Scale button at the bottom of the window.
