Images are larger in size than plain text which means they take longer to load and can slow down your website.However you’ve probably heard the saying: “a picture is worth a thousand words”. Images make your content more engaging and interactive.To improve your WordPress website speed, you need to optimize your images for the web. The best way to do this is by using Photoshop or another image editing software before you upload the image to WordPress. This gives you a lot more control on the quality of images on your website.However, not all users are comfortable working with image editing program. For some optimizing every single image they upload sounds like a lot of work.
Luckily, there are several WordPress image compression plugins that can help you with that. These plugins optimize your images by automatically compressing them and using the smaller sized version on your website.That being said, let’s take a look at the best WordPress image compression plugins, and how they stack up in terms of image optimization, performance, and quality.

3. ShortPixel Image Optimizer
Image optimization plugins are must-have tools for any WordPress website owner. ShortPixel is one of them and I heard a lot of good things about it lately. So I decided to to put it to the test, and see for myself what it can do. For this, I downloaded some free big images, and I added them to my WordPress Media Library. Let’s see what ShortPixel did to them.
ShortPixel: Installation and use
It took a second to sign-up for me to get a ShortPixel account and get the API key from shortpixel.com. The free monthly account includes 100 image optimization credits. We will use them to optimize those large pictures I told you about.
The easiest way to install ShortPixel is from the plugins section of the WordPress dashboard. I went there, I clicked the ‘Add New’ button, and found ShortPixel. Then, I opened the plugin settings, and I successfully validated the API key received by my email. ShortPixel was ready to work and chew some bytes from my big images.
All process took less than 5 minutes and it was straight forward.
How ShortPixel works?
ShortPixel can optimize images individually from the Media Library, but I didn’t have time to lose, so I went directly to the the ShortPixel Bulk page located under the Media section. I clicked the Start button, and the plugin begun to process my images.
4. Compress JPEG & PNG images
Compress JPG and PNG is a WordPress plugin developed by the developers behind Tinypng, a free online image compression tool.

A strong point about this plugin is that it preserves metadata, creation dates, copyright information and GPS location ensuring that you can take full credit for all the images uploaded on your website.

HOW DOES IT WORK?
After you upload an image to your WordPress site, each resized image is uploaded to the TinyJPG or TinyPNG service. Your image is analyzed to apply the best possible optimization. Based on the content of your image an optimal strategy is chosen. The result is sent back to your WordPress site and will replace the original image with one smaller in size. On average JPEG images are compressed by 40-60% and PNG images by 50-80% without visible loss in quality. Your website will load faster for your visitors, and you’ll save storage space and bandwidth!
