They say that “a picture is worth a thousand words,” which is perfectly true when designing a website or publishing content on the site.  And when it comes to building an eCommerce site, images are all that you need to display on your site to get more customers. 

But what if these images turn out to be detrimental to your site?

By using large-size images, you are increasing your website page size, which ultimately increases your site’s loading speed and performance. It’s because images take longer to load and thus slow down your website. 

And it is said that if a website takes more than 3 seconds to load, 90% of visitors leave it before even the page loads completely. That’s a lot of opportunities and customers for any business to lose. However, you can combat this challenge by using image compression plugins.

Here’s a quick overview of the best WordPress image compression plugins –

Wrapping Up

Images are a powerful form of content for any online business, but large-size images can ruin the customer experience by reducing the loading speed of your website. So, ensure that the images are well compressed without distorting the quality. 

All the above-listed plugins are the best for image compression on WordPress sites. However, EWWW Image Optimizer and ShortPixel are my top recommendations because of their built quality, compatibility with other plugins, and, most importantly, the image quality after compression.

Apart from using WordPress plugins to compress images after uploading, you can also reduce the image size using software like Photoshop, ImageOptim (for Mac), and others.
