In order to optimize your website, you need to understand how to compress images. Image compression is a necessity. The efficient compression of images not only ensures faster loading of web pages, it also makes for images that are smaller in size. This not only improves your website’s SEO, it is also a help to the environment.
What is image optimization?
Image optimization is the process of resizing or adjusting the size of the images that you upload to your server. An image can also be referred to as a photo or graphic. Websites have huge amounts of images, some on each page. Each image takes up space, and the more images you have the more file space it takes up and the more bandwidth you will use.
To optimize images, we find a middle ground between keeping the file size small enough that it is quick to load when it is needed but large enough that it looks the way we want. As it is an online medium, the image should be optimized for both desktop and mobile devices.
Issues caused by high-quality images
Image size - You can't just upload any picture you like because it will throw off the entire page's design. If the picture is too small, it will look grainy on some monitors. If it's too big, it will make the page look crowded and your site visitors will have a hard time navigating.
It is more challenging to serve high-quality images because of the following reasons:
High quality images can produce larger file which slows your site. This is very critical on mobile devices. If you serve high quality images then it will consume higher bandwidth which you might not want to spend.
