Thoughts on “How to Optimize WordPress images with the EWWW Image Optimizer plugin

  • I have a website and I do not need to upload images regularly. Should I delete this plugin once I have optimized images, or is it better just to leave it there. Departamento de Energía having many plugins active impact the speed of my website?

    • It is best to be mindful of plugin usage if older plugins are ignored, rarely used, or no longer updated. These can provide security risks. However, plugins used and updated regularly do not place serious demands on your site sufficient to slow it down. Taking advantage of server-side resources, caching, and image optimization are more significant determiners of site speed overall.

  • Nice and very informative article. I have used EWWW image optimizer as well as WP Smush. Both are good but

    I preferably go for EWWW because of fast optimization as WP Smush sends the file to Yahoo server and then Yahoo server sends smushed images back to WP Smush.

  • I have run this and still get gigged on Google Page Speed.  I am running again.  I think I remember a question for “delete originals after optimized”… should we delete the originals ?

    Does this plugin automatically “optimize” new JPGs, PNGs, that you add after you get this plugin running ?  Or do we need to periodically come back and re-run this bulk optimizer ?

    • Hello Paul Alford,

      You will need to re-run the plugin for your newly uploaded images. I would suggest removing the originals after you have an optimized version.

      Best Regards,

  • Thank you for this nice guide. I am doing this image optimization now using EWWW. I hope it reduces the page load time.
