8 Best WordPress Image Compression Plugins to Speed Up your Site

Image compression helps to optimize the images that you add to your website, and thereby improves your site performance. In fact, image optimization plays a major role in determining how soon your site will load. You need to find a balance between image size and quality, and there are several tools that will help you with it. In this article, we will discuss some of the best WordPress Image Compression Plugins that will help you speed up your site.

WordPress Image Compression Techniques

When you consider image compression, you will see there are two different compression techniques. These are lossy and lossless compression. Let’s quickly try and understand the difference between the two.

Lossy compression

Lossy compression means some data from your image will be lost in the compression. However, as a result, there might be some reduction in the quality also. Also, this type of compression is not reversible. Even then, a lot of websites prefer this type of compression due to the fact that it reduces the file size considerably. And as a result, it will have a positive impact on your site loading speed. JPEG is an image format that supports lossy compression.

Lossless compression

Lossless compression, as the name says, does not reduce the quality of the image significantly after compression. That is because it removes only unnecessary meta data from the image. And, quite predictably, the reduction in file size also will be minimal in lossless compression. An example for lossless image format is PNG.
