There was a time when this humble reviewer was banned from their Gmail account for ‘suspicious activity’ for a couple of days, although they had only sent photos in a collection of emails. There were less than 100 photos. Clearly, Google believed that nobody transferred their holiday shots via email anymore in the 21st century, and even though we heartily disagree, we should have thought to reduce the size of those photos before attaching them.
Either way, most Linux users sometimes need to resize images in order to make their size smaller, or to comply with requirements of a particular web site or cloud service. Normally we can use the mogrify command from ImageMagick, which works just fine and has many built-in features other than just resizing. But instead you can choose to use Imgp, a standalone command line utility that’s able to quickly resize, rotate and convert images. The benefits become clear once you run something like $ imgp –x 50% in your directory with test images. Imgp works incredibly fast, leaving its competitors far behind.
Under the hood, Imgp is powered by multiprocessing, an intelligent adaptive algorithm, recursive operations, shell completion scripts, EXIF preservation and other optimisations that together make it work blazingly fast. When launched without arguments ( $ imgp ), it shows a concise yet very helpful description of all possible options. Depending of what you need to do, you can use Imgp to down- or upscale images to a specific size in pixels (for example, create thumbnails), rotate, remove EXIF metadata, convert PNG to JPG, set the output quality and more. Granted, Imgp isn’t as powerful as other fully fledged image converters such as Mogrify, but its main goal is performance. The result will be even more noticeable with heavy loads, like handling gigabytes of images on a production server, or managing a photo library. Imgp is the ideal replacement of most current PNG thumbnailers and we believe that it’ll soon become a part of many other imaging applications.

Imgp works too fast to let you enjoy that freshly brewed cup of tea while your images are resized!
