Last time We was talked about jpegtran. You can check it by link: https://linuxnotes.org/jpegtran-for-image-optimization/ .
Today, We will talk about jpegoptim. jpegoptim is a utility for optimizing JPEG files. It provides lossless optimization (based on optimizing the Huffman tables) and “lossy” optimization based on setting a maximum quality factor.
Installation of jpegoptim
For Debian users:
apt-get install jpegoptim
Usage of jpegoptim
To perform optimization, just run the command:
It is better to use an additional parameter to cut out all metadata that is not needed on the site:
jpegoptim file.jpg --strip-all
To optimize all JPG images in a folder at once:
jpegoptim * .jpg --strip-all
