Shortpixel Image Optimizer is a free image compression plugin for WordPress, similar to add-ons like  Smush, Optimus, and EWWW Image Optimizer. Your website pages will load faster, which means visitors are likely to stay longer on your content. It also improves your SEO ranking, while it ensures that all new images are automatically rescaled. Thanks to reducing the size, you’ll use less storage space in the long run.

While the plugin is free, it limits how many images you can compress per month. You can buy more credits when you run out, or wait for the following month. There are also shortcode options for developers to enhance the functionality, as long as you understand how the coding works. If you want to earn a commission, you can join its affiliate program.

Compress large files

The main function of Shortpixel Image Optimizer is compressing files to save you online storage space and help your pages load faster. Not only can you minimize image files, but it also works on PDFs. When it comes to GIFs, it’s compatible with still and animated versions.

To prevent working on each file manually, you can opt for the plugin to do it for you automatically. You can also convert images from any format to AVIF and WebP.

Integrations and compatibility

The plugin is compatible with many forms, sliders, and NextGen galleries. You can also use it with Gravity Forms if you want to improve loading performance. Other compatible add-ons include watermarks, CloudFlare, and WPML media. 

Free and paid options

The free version of Shortpixel Image Optimizer gives you access to 100 free credits every month. If the optimization is less than 5%, you won’t spend any credits when using the tool. If you run out, you’ll need to buy more, with the lowest amount at 5,000 credits. When the month is over, you’ll receive a new batch of free points.

Making file sizes smaller

Shortpixel Image Optimizer is excellent for making images and documents smaller in storage size so that you don’t use up all your online space. If you have a small site, you can easily get away with using the free version. However, larger websites may need more credits depending on how many images you use.
