When and where possible this will scale your images to 960 by 528 pixels, but will preserve the aspect ratio of those images that won’t scale to these dimensions exactly. Perhaps you have a height and width you are aiming for, but want to preserve the aspect ratio. This will scale all of your images to a width of 960 pixels, the height will be scaled accordingly, preserving the aspect ratio. Perhaps the height isn’t as important as the width. I run the following command to compress jpg file: convert -strip -interlace Plane -gaussian-blur 0.05 -quality 85 source.jpg result. The resizing method here is not restricted to scaling down only. For example, to scale down Maketecheasier.png by 50, we will use the following command: convert < imagename > -resize 50 < newimagename >.You can also resize the image to a specific percentage. That will likely degrade the sound quality too much. The command is: convert < imagename > -resize 600x300 < newimagename >.png files in your directory to a size of 960 pixels by 528 pixels. Don’t convert from one lossy format to another unless you have to. Last months column introduced ImageMagick (IM), a command-line tool thats adept at converting images from one format to another. Place all the images you want to scale in a directory and navigate to that location via command line. convert -density 300 Sample1. Basically, remove the alpha channel by making its background white and turning it off. avif file extension is what tells ImageMagick the export format. You’re in luck! With the ImageMagick -resize option, you can quickly and easily batch scale those images to a manageable size. The following works for me in Imagemagick 7.1.0.2 Q16 with libtiff 4.1.0. ImageMagick is pretty straightforward for single images: convert my-great-image.png my-great-image.avif I’ve use the ImageMagick convert command, followed by the name of the the image to convert (including its extension), then the name of the new image. The last thing you want to do is resize them manually. Unfortunately, this gives you a Pictures directory filled with massive images not optimized for uploading to, and displaying on, a web page. Let’s say you’re writing a series of Blender tutorials and you’re using PrintScreen to grab screen shots.
