6 Best WordPress Image Compression Plugins You Need to Try

Are you looking for the best WordPress image compression plugins? If so, keep reading this article. We will show you six of the popular plugins you can use to optimize your images!

But before going further, let’s look at what WordPress image compression plugins are and why you should use them.

What Are WordPress Image Compression Plugins and Why Use Them

If you run a tutorial website or online store, you will add many images to your articles or product pages. While images help the visitors understand what you are saying, they can also slow down the website.

That’s where image compression plugins come in handy. With the help of an image compression plugin, you can optimize the size of the files without losing quality. So, in the end, you will have the image of the same quality but with a reduced file size.

These days, most image compression plugins automate the task. Hence, when you upload photos to the WordPress media library, the plugin compresses them. If you are also using any shared hosting provider that limits disk space usage, compressing images will help you with that, too.

Now that you know the primary purpose of WordPress image compression plugins, let’s examine what to look for in one.

What to Look for In a WordPress Image Compression Plugin

If you need an image compression plugin, consider these factors:

  • Automatic compression: If the image compression plugin can automate that task, it will save you much time. This way, you do not need to focus on compressing images manually and can focus on other essential tasks.
  • Bulk compression: Consider whether the plugin supports bulk compression instead of compressing images individually (which will take a long time). This will reduce the time required for image optimization.
  • Compression methods: Check which type of compression the plugin uses. Most modern image compression plugins come with multiple compression methods, allowing users to choose a method according to their preferences.
  • Image backup options: Some plugins allow you to keep the original files in a backup folder. This way, if necessary, you can quickly restore the images.
  • Supported formats: You might upload images to your website in PNG, JPG, .webp, or JPEG formats. Ensure the image compression plugin supports these formats and can optimize them.
  • Pricing: Many free image compression plugins are available. Free plugins will be enough if you are new to this system and have a few images to compress monthly. But if you have more pictures to optimize, choose an affordable compression plan.

Next, let’s move to the article’s core, where we will list the popular image compression plugins you should try.
