Top 6 WordPress Image Compression Plugins to Speed up Your Site

“A picture is worth 1,000 words”. Compared to plain texts, images express ideas in a more interactive and engaging way. Our brains focus on visual processing so images allow you to grab the audience’s attention quickly.

Not all images benefit your site in the same way. Low quality and too big images slow down websites dramatically. It pays to resize each image you upload and increase the page load time.

A lot of people would use Photoshop or other editing software to minimize the size of their photos before uploading them to WordPress. However, doing that way sounds like a lot of work for each and every photo.

Luckily, that is not the only method to improve your image sizes as well as website speed. WordPress image compression plugins provide a better solution to automatically compress photos. It will display a smaller sized version of images on your website. The main concern left is which one would be the best option for your site. In this article, we will compare the top 6 plugins to compress images so that you make the right decision.

1. Smush – Compress, Optimize and Lazy Load Images


There is a wide range of choices supporting image unnecessary data removal before uploading. Smush comes as an unlimited and free plugin compressing all of your photos up to 5MB in size forever.

Similar to Smush, this plugin increases your page speed in search ranking by compressing and optimizing previously or newly uploaded photos. While Smush only rescales images up to 5M, EWWW can handle any image file size.

EWWW can be highly integrated with other WordPress plugins, CDN plugins for instance. CDNs like Cloudflare, KeyCDN, MaxCDN, and Sucuri CloudProxy are supported, but you have to clear the cache after a bulk optimization.

Besides, all compression will perform on your server which means you no longer have to sign up for a new API key account.

The plugin might ignore images optimized and stored in the database before. You must force the optimize option to override the default behavior.

3. Compress JPEG & PNG Images
