The following list of the 10 best WordPress image optimization plugins has a way to make your site really speed up.

Why You Need an Image Optimization Plugin for WordPress
Pictures transform any site into a more attractive and interesting place to exist, but there is a secret price for page speed. Beauty photos are eaten up in bandwidth, and they can severely slow down your site, which puts people off and raises the bounce rate. The number of pages that take a long time to load may also negatively impact your SEO because search engines give priority to fast and efficient websites.
This is why an optimization plugin for the image is necessary:
- Reduced loading time: Optimized and compressed images lessen the amount of weight on the page and enable your site to load significantly faster. This will retain visitors and enhance customer experience.
- Better SEO: Google and other search engines favor higher-performing websites. Optimized images lead to the improvement of Core Web Vitals and search position.
- Less Storage and Bandwidth Consumption: Smaller picture files occupy less hosting space and consume less bandwidth, which is vital to those sites that have numerous pictures.
- Improved Mobile Interaction: Optimized image loading will be facilitated across all devices and leaving mobile visitors with a positive browsing experience.
- Automatic Optimization: Compression, resizing, and format conversion are done automatically by most of the plugins and therefore save time and effort, ensuring that your site remains efficient.

Tips to Optimize Images for WordPress
Image optimization does not only imply installing a plug-in; you can also adopt a few best practices to optimize it. Here are some tips:
- Select the Best Format: Photos are better with JPEG format, graphics with transparency need PNG format, and the last generation formats, such as WebP or AVIF, to load faster and have a smaller size.
- Resize Before Uploading: Do not upload large pictures that are not necessary. It is possible to resize them to the exact display size of your site and save some space and load time.
- Compress Photos: It is always recommended to compress your images to a smaller size before uploading, using embedded 3rd-party tools or external software to decrease the size of the file, but with no significant loss of quality.
- Enable Lazy Loading: Lazy loading is through which images are loaded only as they are seen on the screen. This enhances faster loading of the first page and customer satisfaction.
- Clean out Unused Pictures regularly: Unused pictures in your media library build up over time. Eliminating them will decrease the load on the server and make your site lean.
