Let’s talk about image optimization and the best 7 WordPress plugins to reduce image size in a brief. 

What Do Plugins for WordPress Image Optimizer Do?

Image optimization is the process of changing an image’s size to make it load more quickly and take up less disk space. It involves a two-pronged approach: You want your photographs to load as rapidly as possible and you want to ensure that they look their best.

The usage of an WordPress image compress plugin is the most obvious option to accomplish both of these objectives at once. Plugins for image compression do much more than merely improve the graphics on your website:

  • It employs lossless compression to reduce the size of your photographs, individually or collectively (no quality is lost in the image file).
  • lazy loading to improve the speed of the page
  • Auto-resizing
  • They can make the image files smaller.
  • Delete any extraneous metadata
  • Remove any Exif information that could be there.

Why Is WordPress Image Optimization Vital?

It’s very important to optimize the photos on your WordPress website. Here are four explanations:

  • Boost the speed of web pages. Unoptimized photos bloat and slow down the loading of your website pages. WordPress may be made faster by optimizing your huge photos without compromising on quality.
  • Improve user experience. Visitors to websites find it annoying to have to wait longer than usual for a page to load. For websites that take longer than three seconds to load, the bounce rate—the percentage of visitors who arrive on a page and leave without exploring the rest of the site—is very high.
  • An improved search engine optimization (SEO). Search engines like Google reward websites that load quickly and punish those that load slowly. You have a better chance of ranking well on search engine results pages if your website is quick and your photos are optimized (SERPs).
  • Conserving disk space You may use your hosting resources more effectively by optimizing your WordPress images. You will have more room to add more sorts of content and features to your website if your image files take up less space.

How to Select the Most Appropriate Image Optimization Plugin

WordPress image optimization will shorten load times and enhance user experience.

But what exactly do you do after image optimization? Delivering high-quality photos in the proper format, dimension, and resolution while keeping the size as little as feasible is known as web image compression.

There are several methods for optimizing photos, including scaling, compression, and lazy loading caching.

There are several plugins available that can perform this task automatically for you. However, not every plugin is made equally. We’ll go over some of the most important characteristics to consider when picking a WordPress image compress plugin in this section.

  • The practice of automatically encoding or transforming an image file so that it uses less space than the original file is known as a compressing function.
  • Verify that the plugin supports the desired file types, including JPEG, PNG, PDF, GIF, and WebP.
  • Images automatically converted to WebP format: A cutting-edge image format called WebP offers greater lossless and lossy compression for pictures on the internet. The plugin you select should support and convert this highly efficient web standard.
  • The lazy load option uses less bandwidth by only displaying images when visitors request them.
  • Select whether you want your image to be compressed using a lossless or lossy approach for optimization. Then, confirm that the plugin offers both options in accordance with your requirements. a choice that enables you to optimize the pictures that are currently on your website.
  • Both options—bulk optimization vs. individual optimization—are quite helpful because you might wish to bulk-improve your current media collection or manually choose whatever image to optimize.
  • If you need to return to the original photos, you have a backup option.
