5 Best WordPress Image Optimization Plugins to Speed Up WP sites
By James Flarakos | December 12, 2022
Comparison of the 5 best WordPress image optimization plugins and how they can help speed up your website, increase SEO and benefit your visitors with faster page loading times.
How Can Image Optimization Plugins Help Speed Up Your Site?
Plugins can help optimize your images in many ways, foremost it uses compressions to compress your images and create a smaller image file. By having smaller image files they will load much faster on a page. If your have many large images on one page this can cause long load times, leading to visitors leaving or getting frustrated.
Next thing they use is lazy loading, this means when a visitor opens a page on your website, rather than loading all the images or videos at once it will load them only as the viewer scrolls to that section. This optimizes loading times as the page wont have to load every single image on first load and rather only loads one or two at a time as the user scrolls down the content.
Converting images to WebP format is another way the optimize your WordPress images, this new more efficient method of compressing images.
Finally, some of the plugins also use caching to help with loading times, this will let the users browser remember a your website page in their cache. So after the first visit the browser wont need to keep loading the page, rather it loads the cached page. This means that pages with images get better optimized due to the page not having to load from new every time.
If you don’t feel confident in using plugins or find the tutorials a bit hard to understand, take a look at our technical support services and how we can help optimize your website for you.
