When do you need a WordPress Image compression plugin?

Images are usually larger in size than the plain text which means they take a longer time to load and can slow down your website.

However, you might have probably heard the saying: “a picture is worth a thousand words”. Images make your content more engaging and interactive.

Thus to improve your WordPress website speed, optimization of images for the web is a necessity. The best way you can do this is by using Photoshop or another image editing software while before you upload the image to WordPress. This gives a lot more control over the quality of images on your website.

However, not all users are comfortable while working with image editing software or programs. For some even optimizing a single image, they upload sounds like a lot of work.

For solving this there are several WordPress image compression plugins that can help you with that. These plugins optimize your images by automatically compressing the pixels of those pictures and using the smaller sized version on your website.

That’s why it requires to take a look at the best WordPress image compression plugins, and how they stack up in terms of image optimization, performance, and quality.

Why the image loses its quality while changing its size?

An image is mapped as a grid of pixels commonly known as a bitmap format. Each pixel has been assigned with a total value. When you change the size of the image you actually change the megapixel count (total number of pixels in the image) due to which your image loses its quality.

When you resize an image you either make each pixel smaller or larger, once each of that pixel gets too large then it is visible to naked eyes and the picture looks pixelated and blurry.

How to solve this?

To overcome the image quality issue we need to compensate for each enlarged pixel by resizing the image. This method is known as Fractal interpolation or resampling of the images. This technique gives us a quality result during the enlargement of the image.
