There are many WordPress plugins that have been specially developed for image editing and image optimization. They make it possible to edit images directly in the WordPress media library.

In this article, we present five of these WordPress plugins and explain how you can use them to optimize and improve the images on your website. So that your WordPress website offers the best possible performance. See also our e-book Making WordPress faster with other important tools.

What are WordPress plugins for image editing and optimization?

WordPress plugins are extensions that can be integrated into the content management system (CMS) and have been specially developed for use within WordPress. They enable all users to edit, optimize and manage images within the CMS. 

Other image editing programs, such as Adobe Photoshop, Figma or GIMP, are separate applications that can be installed on the user's computer and used independently of a CMS. 

These programs usually offer a more extensive range of editing functions and tools. However, inexperienced users usually require a significantly longer training period and the application is often more complicated than with WordPress plugins.

What problems can arise if I do not optimize images on the website?

If you don't optimize the images on your website, this can lead to some problems:

  • Longer loading times: Unoptimized images often have a larger file size and therefore take longer to load. This can affect the loading time of the entire website and cause visitors to leave the website before it has even loaded.
  • High data consumption: More data is consumed if your images are unoptimized. This can be expensive for visitors who access the website via a mobile connection.
  • Search engine optimization: Search engines such as Google take into account the loading times of a website when determining its ranking. If a website is slow, this can therefore lead to a lower ranking in the search results.
  • Poor user experience: A website with slow loading times and unoptimized images can be unpleasant for visitors. There is a high probability that they will not recommend the website to others or visit it again.
  • Waste of server resources: Unoptimized images require more storage space and computing power. This can lead to the server being overloaded and the website becoming slower.

So as you can see, it's important to optimize the images on your website to avoid these issues and improve the user experience.

WP Smush is one of the WordPress plugins designed to automatically optimize the image size and improve the loading time of your website. It removes unnecessary metadata from image files and compresses them without affecting the quality. The plugin supports the optimization of JPEG, PNG and GIF images. It can also optimize multiple images at the same time and offers a simple method for optimizing images that have already been uploaded.

WP Smush and WebP

WP Smush is a very useful tool that can reduce page load time and thus improve the user experience. The speed of a page is an important factor for search engine optimization (SEO), as search engines consider the loading time of the page as a ranking factor.

The plugin uses various techniques to reduce the image size without affecting the quality. It also offers the option of optimizing images that have already been uploaded, even with several images at once.
