Go to the directory where you have the images. You might ask how to compress the images in the entire directory, that’s not difficult too. Optimize Image Fix Size Batch JPEG Image Compression and Optimization However, you can compress the given image to a specific size to, but it disables the lossless optimization.įor example, let us compress above the image from 5.6MB to around 250k. The above command optimizes the images to the maximum possible size. The source and compressed images will have the same quality. Open the compressed image in any image viewer application, you will not find any major differences. Here the actual file size is 6.2MB, now compress this file by running: $ jpegoptim tecmint.jpeg Let’s now compress the following tecmint.jpeg image, but before optimizing the image, first find out the actual size of the image using du command as shown. The syntax of jpegoptm is: $ jpegoptim filename.jpeg Next install jpegoptim program from the repository as shown: # yum install jpegoptim On RPM based systems like RHEL, CentOS, Fedora etc., you need to install and enable EPEL repository or alternatively, you can install the epel repository directly from the commandline as shown: # yum install epel-release

On Debian and it’s Derivatives # apt-get install jpegoptim To install jpegoptim on your Linux systems, run the following command from your terminal. This tool supports lossless optimization, which is based on optimizing the Huffman tables. Jpegoptim is a command line tool that can be used to optimize and compress JPEG, JPG and JFIF files without losing its actual quality.

Compress or Optimize JPEG Images from Command Line Using these two tools, you can either optimize a single or multiple images at a time.

OptiPNG – is a small program that optimize PNG images to smaller size without losing any information.Ĭompress and Optimize JPEG and PNG Images in Linux.

jpegoptim – is a utility to optimize/compress JPEG files without loosing quality.

However, here are two simple command line utilities to optimize images and they are: You have a lot of images, and want to optimize and compress the images without losing its original quality before uploading them to any cloud or local storages? There are plenty of GUI applications available which will help you to optimize the images.
