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:
