Can I Use Free Plugins To Optimize Images In My Website?

Yes, Free plugins are absolutely fine to use unless you have some extra requirements. You can go with any of the plugins mentioned above. They perform very well even in the free version.

How Can I Optimize A Scaled Image?

Run your site on GTmetrix and see the maximum display size of the image. Resize the image to that size. Now, compress the image. Remove the unoptimized image and upload the new one.

Is Image Compression Same As Image Optimization?

Image compression is a part of the whole image optimization process. In image compression, the image size is reduced making sure that the quality of the image is maintained throughout.

How Image Optimization Plugin Can Help Your Website Load Faster?

Well! First, let’s understand how the images can make your site load slower. Images are always more extensive than the plain text. This means they take a bit longer time to load compared to plain text. If your images are not correctly optimized, they can make your site load slow.

However, the image takes longer than text to load does not mean that you should use only text in your content and avoid images.

Instead, you should use images in such a way that they are served on your website in a much faster way. You can do this by using different image optimizing tools that are mentioned above.

How To Know If You need Image Optimization Plugin?

Before you go for an image optimization check, I suggest you check the site speed to see if your site is loading at an average pace. If your site is taking longer than the average load time, the unoptimized images can be one reason for this.

My favorite tool for checking the site speed in Gtmetrix.

You can also use the tools like Dotcom tools & Pingdom

Here I performed the Gtmetrix speed test for a blog page. The page load time here is 7.8 sec ( higher than average load time) which is not bad for which unoptimized images can be one of the reasons.

What next?

Now I will install a WordPress image compression plugin to optimize the image for the website automatically.

My favorite image optimization plugin here will be Smush.

This plugin will automatically optimize the image during the upload and optimize all the old images in bulk.

Now I performed the new speed test again( not the Re-Test ) to see if that made any impact on the page loading time

The page’s speed is now reduced to 5.8sec from 7.1 sec after the plugin was activated.

This is how the use of a plugin can help you load the WordPress website faster by optimizing images using image optimization plugins.
