The EWWW Image Optimizer plugin by Shane Bishop will reduce image file sizes in WordPress using lossless/lossy methods. It will automatically optimize new images as you upload them and can also optimize existing images that you have already uploaded to your WP site.
The benefits of using the EWWW plugin are faster page loading and backups—due to smaller file sizes, less bandwidth usage, better JPG and PNG optimization, and the plugin runs fast without needing root access to your server.
After installing and activating the plugin, you can access the settings page from the WP dashboard settings menu. I recommend you read the plugin documentation before setting or changing anything here. You can start using EWWW right away without changing the default settings. Keep in mind though that for maximum optimization speed, you may have to enable certain options. The downside is that more optimization may mean a slightly lesser quality image. So, you’ll have to decide for yourself what type and how much optimization processing you need for your site.
You won’t notice anything different when you upload a new image using EWWW. In fact, you need to go to the List view in your media library to see the results. Here, you can see that my image has been optimized and the size reduced by 6.3%.
To optimize your existing images, you access the Bulk Optimize tool from the Media menu. Be aware that if you have a lot of images on your site, it will take a while to optimize all of them. On my site, the first 50 images took over 17 minutes to process. The great thing about the Bulk Optimize tool is that it does have resume capability–which is great if your bulk processing gets interrupted for some reason. You can go back and begin where you left off. Or like in my case, if you have a ton of existing images, you don’t have to optimize them all at once.
For photo blogs and other WordPress sites with lots of images, the EWWW Image Optimizer plugin is a great way to speed up your website. With search engines putting more emphasis on site speed, a plugin such as EWWW is a must.
