Whether you're prepping images for a presentation, optimizing them for web use, or just trying to save some disk space, resizing images is a fundamental skill that comes in handy. This guide will walk you through the simplest ways to resize images on Windows, macOS, and ChromeOS.
If you're a Linux user and want to resize images in the terminal, you'll need to install a software suite like ImageMagick. If you're using a Linux distro, like Ubuntu, there is a pre-installed image viewer, but this won't allow you to resize images, so you may want to install a third-party application to do this.
