Image plays an imperative role in making your website resonate with your visitors.
Visual imagery generates emotions and responses that are fundamentally unpredictable or uncontrollable and is an effective mode of appealing them over.
Insertions of appropriate and sharp images are vital for a website to connect with the users but high resolution images have certain drawbacks in term of loading speed.
Furthermore, Google and other search engines confer high preference to web pages that are highly optimized for speed while as slow site speeds degrade the user experience.
I’ve short listed some magnificent image optimization plugins for WordPress that can enhance your site pace without compromising image usability factor.
