The extended process consumes few seconds. The '-brute' option takes the file through 114 filter/compression methods. #Image convert size install#Users of other Linux distributions can install it using their standard installation commands followed by pngcrush.Īfter the installation is done, we can reduce the size of PNG file by running: pngcrush -brute Reducing PNG file size It reduces the file size of the image by passing it through various compression methods and filters.ĭebian/Ubuntu users can run the following command for installation. Pngcrush is a PNG (Portable Network Graphics) file optimizer. The applications for convert and mogrify are identical as they are derived from the same package. Moreover, mogrify command supports expressions to queue in multiple files. The main difference between convert and mogrify command is that mogrify command applies the operations on the original image file, whereas convert does not. There is an alternative for processing multiple image files, which is mogrify that comes within the ImageMagick package.Ģ. In order to convert multiple files, we need a bash script that runs a loop for all images. #Image convert size manual#We can refer the manual pages by man convert to master the image formatting tool. The convert command has hundreds of applications like rotating an image, applying effects or drawing stuff on an image. In the above snippet, we converted a ‘.png’ image file into a ‘.jpg’ file. The reduction in quality is 92% if no parameter is provided. Some websites only support specific file extensions, therefore convert command provides the facility to convert the image format. In order to reduce the image into the exact dimensions, and neglecting the aspect ratio, '!' must be used after the resize parameter. The idea behind the conversion is that the reduced image must fit inside the specified dimensions. The aspect ratio of the image is restored even though the dimensions provided in the command violated the original aspect ratio. The reduction in the quality of the reduced image can be observed when we stretch its dimensions. convert -resize 200x200 Reducing file size by pixels For this purpose, we need to provide the new width and height. The file size of image can be reduced if we reduce the amount of pixels it holds. Reduce File Size of Images in Linux by pixels In the above command, we display the amount of space occupied by all the versions of “jd_logo”. The du command provides the amount of disk used by files in Linux. In case we want to examine the new file size, we can do so by: du -h jd_logo* There is a significant reduce in the quality of the image using the convert command. convert -quality 10% Reducing image by quality The simplest way of reducing the size of the image is by degrading the quality of the image. Once the package is installed we can run man convert to take a look at the variety of operations supports by the command. Debian/Ubuntu users can install ImageMagick by running: sudo apt install imagemagick The convert command comes under the ImageMagick package. Using the convert Command to Reduce File Size of Images in Linuxīefore we move onto the application of this command, let us make sure it is present in the system. Let us quickly delve into the processes of reducing image file size. There is a constant need of reducing the file size of such large images, therefore, we bring you an article which deals with the said task. With the increase in the focus on the quality of images, the image file sizes have been increasing tremendously. To resize a photo called PXL_20210413_015045733.jpg to a more manageable 500-pixel width, type this: $ convert PXL_20210413_015045733.jpg -resize 500x sleeping-cats.In this article, we talk about the different ways to reduce the file size of images in Linux.
