Why We Love Image Optimization (And You Should, Too!)

image compression for blog website optimization

Most of the images and photos that we create or click nowadays occupy much larger space in memory. This is due to higher amount of pixels that cameras capture and the advent of displays with larger resolutions. Few years back, in the Internet also, we used 2G networks to browse the web but now even 4G connections sometimes seem slow due to large amount of images and video content.

If you are running a website or blog, it is important to optimize such multimedia content to provide rich user experience. According to various statistics, 47% of users expect a website to load in just two seconds. Failing to meet this requirement results in loss of engagement and decrease in conversions.

So what are the benefits of compressing images?

  • Reducing the Website loading time
  • Occupies less space in server
  • Improves search engine ranking (Google does take in to account of various parameters including load time)

Below are few of the best tools that will assist you to compress images with little or no loss in clarity.

Lossy compression is a method where a small amount of clarity is reduces but delivers higher compression rates. It can be used where the resolution of the image is less important. On the other hand, lossless compression retains the sharpness of the image yet providing decent level of optimization.
