Using high-quality images makes a site more appealing. However, using too many pictures can slow down the performance of your site.
There are many advanced WordPress image optimization plugins. But even plugins can slow down the performance of your website or they may even destroy the image’s quality.
In this article, we would like to discuss how to optimize WordPress images without a plugin.
Why Optimize WordPress Images without Plugin?
If you are planning on having a successful site with a lot of traffic, you must follow certain rules. As mentioned above, having images on your site is very important. By using pictures related to your content, other than making the post more appealing, you can add to your content’s wealth. You have probably heard the famous saying “A picture is worth a thousand words”.
But the problem is, having a lot of images on a site can reduce the performance. Users prefer a site that loads fast and without any issues. When your site’s speed is slow, they would probably leave your site before waiting for it to be fully loaded. As a result, you will have a negative bounce rate.
This issue has a direct impact on your ranking in search engines such as Google. Users usually wait only a few seconds for a site to load and if it takes longer, they leave for another site. Google fully understands this and gives negative points to your ranking.
The best solution is to have optimized images on WordPress. Image optimization means reducing the size of the image without sacrificing quality.
Using optimized images on WordPress improves SEO and UX. As a result, your site’s traffic increases. There are a lot of plugins in the WordPress repository that can optimize WordPress images.
But some users prefer not to install any unnecessary plugins, this is one main reason why most users don’t install any third-party plugins.
Installing plugins could leave you with a few issues:
- The installed plugins may be heavy and have a negative effect on your site.
- The installed plugins may not be compatible with your activated theme.
- Some plugins may change the appearance of your site.
Therefore, there are online tools designed specifically to optimize WordPress images without a plugin.
