WhatIs.com defines image compression as minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level.
There are several main advantages when it comes to image compression:
- Compressed images will take up less memory.
- It will be easier for web pages to load.
- You will be able to send the images much faster via the Internet.
You can insert more images that are compressed without slowing down page load speed which, without compression, wouldn’t be the case.
One of the factors for Google SEO (Search Engine Optimization) rankings is the speed of page loading.
That is why it is important to do everything you can in order for your page to load in the shortest possible time, and compressing images is one of those things.
Researches showed that 53% of people will leave a mobile page if it takes longer than 3 seconds to load.
With that in mind, you certainly do not want to turn people away from your website.
Google also indexes how many people are turning away from your pages, which also affects your position in the search results.
