imgmin is a CLI app uses a lossless mechanism to generate the optimized images
by manipulating pixel blocks. imgmin offers an automated means for enforcing
image quality as a standalone tool and as a webserver module. imgmin
determines the optimal balance of image quality and filesize, often greatly
reducing image size while retaining quality for casual use, which translates
into more efficient use of storage and network bandwidth, which saves money
and improves user experience.
The JPEG quality settings most used by graphics professionals tend to be
highly conservative because Compression and image quality are inversely
proportional and graphics people are interested in utmost visual quality and
not in spending time worrying about network efficiency.
The result of overly conservative JPEG compression and webservers' inability
to compress them any further means that many images on the web are too large.
JPEG's overwhelming popularity as the most common image format means that many
pages contain dozens of JPEG images.
These bloated images take longer to transfer, leading to extended load time,
which does not produce a good viewer experience.
