5 WordPress Image Optimization Plugins For Faster Page Speed

5 WordPress Image Optimization Plugins For Faster Page Speed

Most websites don’t skimp when it comes to images. A single blog post can have dozens of photos and screenshots, as the media makes the content more attractive and scannable. However, the more images you add to each page, the longer it will take to load. That’s where a quality WordPress image compression plugin can come to the rescue.

This type of tool takes your images and “optimizes” them to take up less space. In this article, we will highlight the best WordPress image optimization plugins available. We choose them based on their feature sets, ratings and analysis, update history, and pricing.

Let’s go there!

EWWWEWWW Image Optimizer

EWWW Image Optimizer is one of the most powerful WordPress image compression plugins that you can use. Once you enable this tool, it automatically compresses any new images that you upload to your website.

You can also use Bulk Optimizer to compress existing images in your media library:

With EWWW Image Optimizer, you can automatically resize images when uploading and removing metadata from your media files to save space. The plugin also includes lazy loading functionality and allows you to convert image files to the WebP format to increase compression rates.

The free version of EWWW Image Optimizer compresses images on its own server and does not have a file size limit. You can also go for the premium version of the plugin, which uses a cloud service to optimize the image and has higher compression rates.

Main features:

WP Smush is part of the WPMU DEV plugin family. This specific tool allows you to automatically optimize images after uploading them to your website. Like our previous pick, WP Smush includes a bulk optimization option (up to 50 images at a time) to compress existing images.

What really stands out about WP Smush is its user interface (UI). As with most WPMU DEV plugins, the display is elegant and easy to understand:

WP Smush also includes resizing and lazy loading features. Also, you can configure the plugin to remove metadata from the image after uploading new files.

This particular plugin supports images up to 5MB. If you want to exceed this limit, you will need to use the premium version, which also allows you to integrate a Content Delivery Network (CDN) for even faster load times.

ShortPixel Image Optimizer

ShortPixel Image Optimizer allows you to automatically optimize images and PDF files, as well as resize images. Although this is a standard offering, a new feature offered by this plugin is the choice between lossy, lossless, and brilliant compression.

Few WordPress image optimization plugins offer brilliant compression. From a technical point of view, it provides a middle ground between lossless and lossy compression types:

ShortPixel Image Optimizer also allows you to backup original image files after optimization. It can help you remove metadata from images and resize them automatically after the upload process. Also, this plugin can automatically convert PNG files to JPEG as well as optimize Retina images and thumbnails.

Despite all its advanced features, there are some drawbacks to using ShortPixel. First, the plugin requires you to share your email address to obtain an API key for activation. Second, the free version of the plugin limits you to 100 image optimizations per month, which may not be enough for some users.

Main features:

  • Automatically compress new images on your website (up to 100 per month)
  • Use bulk optimization to compress existing images
  • Choose from lossless, lossy, and brilliant compression
  • Create backup copies of your images before compression

Compress JPEG & PNG Images

Compressing JPEG and PNG images is a simple tool to optimize images in WordPress. By default, this plugin aggressively compresses images with lossy focus. It allows you to automatically resize images and compress all the sizes that WordPress generates when uploading new files:

One downside to using Compress JPEG and PNG is that you have to sign up for a free Tinify account to get an API key. Additionally, the service limits you to 500 free image optimizations per month. Each additional image size that you want to compress takes up another space.

Main features:

  • Optimize images when uploading to WordPress or in the background after they are on your server
  • Resize images automatically

Compressing JPEG and PNG images is for you if …

… You want a simple plugin that aggressively optimizes images. In our experience, files generated by JPEG and PNG Image Compressor still look great for most purposes.
