WP Smush vs Imagify – WordPress Website Maintenance Tip


Poor website load speed and performance is commonly due to the images on your web pages. Either they are too big in dimensions or too large in file size. resizing images is the easy part but what about reducing the file size of an image? This can be a little tricky if you are not experienced.

Luckily there are 2 free WordPress plugins, which will automatically reduce the file size for all your images allowing website speed and performance to be boosted. We have asked who are an experienced website maintenance company based in the UK to give us their professional thoughts and opinions about WP Smush and Imagify and which is the best one to use on a WordPress website.

What Are These Plugins For?

These 2 plugins compress images to reduce the data size of the file without losing any quality of the image. It is always recommended to use JPEG images wherever possible than PNG images. PNG’s require a large amount of data, mainly for transparent backgrounds.

If you reduce the data size of all images on a web page you could save 1.2mb per page by compressing the images correctly. This will reduce the amount of time a web page takes to load, increase search engine rankings and give a better user experience.

WP Smush and Imagify are completely free to use with an option to purchase premium packages if you’re adding high volumes of images on a regular basis.

We have used the same image and ran it through both plugins to see which gives the better compression to help aid your WordPress website maintenance.

WP Smush

WP Smush was built by wpmudev and provides free use of image compression. They do boast that their premium package compresses images twice as much along with automatic PNG to JPEG conversion.

The Test.
  • Original image size: 548KB
  • New image size: 548KB

It’s free. If you don’t resize the dimensions of your images to there correct size then WP Smush gives you 12 resized images for you. These are your basic WordPress dimensions such as large, medium, small, thumbnail etc.


This is completely useless if you require different sized images outside the set WordPress set dimensions. You need to pay for the premium version to reduce the original image size. Maybe this plugin is ok for people who are new to website maintenance but is completely useless to people that actually work on their images professionally.



Imagify was built by the same people who created the WordPress website performance plugin, WP Rocket. The free Imagify plugin comes with a free 25mb package, which allows you to process up to 25mb of images per month (roughly 25-35 large images).

Paid versions start from $4.99 per month for 1gb and up to 50gb for $69.99 per month.

The Test.
  • Original image size: 548KB
  • New image size: 103KB


All images, including your original image, gets reduced. This applies to the free version as well. The reductions are huge without any loss of image quality. The test we ran gave our image a huge image size reduction. This will save a huge amount of load time performance issues throughout your website.


The only small disadvantage for Imagify is that you need to signup and create an account. Not too much of a problem but a little inconvenient for a plugin.

if you have a large website with a lot of images, it will take you a very long time to reduce all your images due to the 25mb per month cap.


Which Is Best?

We used to use WP Smush until we were contacted by Imagify to give their plugin a go. We have fully switched over to them now and use Imagify for all our website maintenance clients. Even if you have a large amount of images, the paid versions are worth the money.
