How do you need a compression plugin for your WordPress image?

Images are bigger than plain text so they take longer to load and can slow down your website.

You probably heard the saying, however: “a picture worth a thousand words.” The images make your content more interactive and engaging.

You need to optimize your images for the Web to improve your WordPress website speed. The easiest way to achieve this is to use Photoshop or other image processing tools before posting the file to WordPress. This gives you a great deal of power over the picture content on your website.

Not all people work happily with the picture processing software, however. Sounds like a lot of work to others automate any single picture they upload.

Fortunately, there are several compression plugins for WordPress pictures that can support you with this. These plugins transform the images by compressing them dynamically and making use of the smaller version on the website.

Having said that, let ‘s look at the best compression plugins for WordPress images, and how they stack up in terms of image processing, speed , and efficiency.

reSmush.it is the perfect compression plugin for WordPress images. It allows you to optimize the upload images automatically as well as offer a bulk optimization option for older images.

This uses the reSmush API to optimize images and allows you to pick the level of optimization for your uploads. The downside is that it has no different degrees of compression.

Using the plugin does not require an account, but for extra functionality you should sign up for their API.
