Top 7 Image Lossless Compression Plugins for Speeding Up WordPress

Lossless image compression is a big deal, more often than not it is the actual image files that slow our site down significantly, and slow sites are known to cause much higher bounce rate, as well as much lower level of satisfaction. Although image compression technology is still being worked on, and hopefully we will see native browser integrations in the future, there are a number of tools and plugins available today that can help us shed off unnecessary bytes, kilobytes and in some cases megabytes from our images.

WordPress bloggers are one of the most widely known group of writers that utilize a lot of images in their content, especially so for sites that do list, gallery and how-to posts on daily basis. The upload folder for images can quickly grow huge, but so you can the load time of each webpage that is serving these images. Perhaps, the process of having to manually optimize each image sounds time consuming, and people just decide to not do it at all.

Thanks to some bright developers and a number of tools, we have a number of free and premium WordPress lossless image compressions plugins available at our disposal, which we will be taking a look at in this post. Please share your own methods and techniques for compressing images in the comment section.

EWWW Image Optimizer

EWWW Image Optimizer

EWWW Image Optimizer, one of the leading loseless image optimization plugins, will automatically optimize/resize all of the images that you upload using the WordPress media manager. You will also be able to use a feature that will let you optimize all your pre-existing images, and have them converted/optimized for the best possible file size and image quality.

EWWW Image Optimizer is built by developers who are highly educated in image optimization and understand how important image optimization can for having your site load faster, use less bandwidth, and optimize overall site performance, not to mention save a ton of disk space which will make it more effecient to make regular site backups.

WP Smush

WP Smush

WPMU DEV have built an image optimization plugin that’s used by more than 300,000 WordPress users. WP Smush optimizes images by removing hidden and junky image data, optimizing the image file size without sacrificing its quality. In their own words — the faster you can make your pages, the more likely you’re going to earn attention from search engines which will lead to higher rankings and more organic visitors.

TinyPNG

TinyPNG

TinyPNG is one of the most recognized lossless image compression services that compress both JPG and PNG type files. Up until very recently, the service did not provide a WordPress plugin, but since that has changed, several thousand WordPress users are now using this magnifcent plugin to automatically optimize images as they are being uploaded. One thing to keep in mind about this plugin is that you will be limited to 500 image optimizations every month, which actually is enough for small/medium sized WordPress blogs. To extend the limit you will need to share your bank details, but even then — the image optimization plans are quite cheap. Those who wish to really optimize their images will be happy to learn that there is a bulk image optimization service possible, though you may want to look into the limits and their pricing first.

ShortPixel

ShortPixel

Both new and old images can be optimized with ShortPixel. Once activated, the plugin instantly processes new images uploaded to your website. Bulk optimization will automatically process all your past image gallery with one click. Images and thumbnails are processed in the cloud, and replaced back into your website. It’s simple to use, yet incredibly powerful. The only thing that might be seen as a downside for ShortPixel users is that the monthly limit is going to be 100 images, which is four times less than TinyPNG. Still a good alternative to have.

Optimus

Optimus

After installing Optimus, each new image that will be added to your image library will be automatically optimized through the use of Optimu’s servers. At no point do you lose track of your original images and their content, but the whole process happens in the background so you don’t have to worry about a thing. Each image will be allocated a new field that will show how big of a file reduction was taking place. The one thing that makes Optimus stand out from other image compression plugins is that Optimus never loses the quality of your original images. Custom options allow you to keep all the necessary image data without it having an effect on the overall file size.

  1. Hello, thank you for summary but I still don’t know which one is the best… WP.Smush.it is good and simple but does not show me the best results.

    1. Gayatri,

      It depends what you mean by “best results”. It offers lossless compression therefore your images will look exactly the same with the same quality but will be smaller in size. If you have uploaded images that has high resolution it won’t help you because it isn’t resizing images but reducing them in size.
