  • Share on Pinterest

WordPress by default compresses and optimizes images for web-use. Usually, the max width and height in WordPress Media settings do not exceed 1024 px. What happens if the dimensions are greater than 1024px?

After testing for page speed with PageSpeed Insights, recommendation to re-size the website’s images.

This could affect the site’s page ranking in Google, especially when you are you running a multi-author site. It’s difficult to monitor images uploaded by other users.

Also, large image files may be slowing down your site without you even knowing it.


To scale the image dimensions, you can try the following plugins




The plugin automatically scales the images upon upload. You can bulk resize images or select to resize one image at the time.



WP Smush

My personal choice, it’s the WP Smush plugin. Bulk re-sizing and optimizing images. Saved my ass and my time several times (sorry for the language 😉 ). The best part is that WPMU DEV server doing all the job, it’s resizing and optimizing images on.

This plugin can automatically resize images upon upload, or bulk resize all the images in the media library.

You can try the WP Smush Pro, it’s even better.
