Sometimes you’ll need to not only resize an image, but also crop it so there’s nothing overlapping. Resize to specific dimensions and keep the aspect ratio convert original.png -resize 100x100^ new.png.One of the two dimensions (either width or height) will be scaled exactly, while the other will be scaled proportionately and may overlap: You can also append ^ to the dimensions to tell ImageMagick that you’d like to resize the image to fill the dimensions, potentially overlapping on one side. What it will do is resize the image to fit within those dimensions. This won’t actually resize the image to the exact dimensions specified. convert original.png -resize 100x100 new.png.To resize an image to specific dimensions, use the convert command with an input file, the -resize parameter, your preferred dimensions, and an output filename: Resize to specific dimensions and keep aspect ratio curl =compress,format -output image.jpg.If you don’t already have a sample image handy to work with, you can download the header image from this tutorial using curl, and save it as image.jpg: On Ubuntu 22.04, you can install it with apt. However, it is widely available in package managers for all platforms. The ImageMagick library is very popular, but doesn’t usually come installed by default. You can learn how to configure a regular user account by following our Initial server setup guide for Ubuntu 22.04. Prerequisitesīefore you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server. It has libraries for integration into almost all popular programming languages, and you can use it directly with its included commands, mogrify and convert. Essentially, ImageMagick is the most commonly-used program for resizing, converting, or otherwise manipulating images on the command line. If you’ve ever done programmatic image manipulation, you have probably encountered the ImageMagick library or its major fork, GraphicsMagick.
