4. ShortPixel

"A freemium easy to use, comprehensive, stable and frequently updated image compression plugin."


Key features

  • Compress JPG, PNG, GIF (still or animated) images and also PDF documents
  • No file size limit
  • Option to freely convert any JPEG, PNG or GIF (even animated ones!) to WebP for more Google love

What people say

ShortPixel is an image optimization tool that compresses images for the web, shaving off vital seconds on page-load times but also saving WordPress users the hassle of having to try to resize and compress their own images before uploading to their site. The free version is plenty for the average user but again, it's worth paying for premium if you're doing client work.
Dan Gissane, Website Consultant and Founder of Huxo Creative
This is a plugin that shrinks the file size of images on your website without losing quality. While the quality of the “shrinking” is really good the standout for me is ease of use.
David Katic, Founder,

5. Asset CleanUp

"Don’t just minify & combine CSS/JavaScript files ending up with large, bloated and slow loading pages: Strip the “fat” first and get a faster website."

Asset CleanUp

  • Decreases the number of HTTP requests loaded and eliminate render-blocking resources
  • Preload CSS/JS, Local Fonts & Google Fonts files
  • Minify CSS files
  • Minify JavaScript files

What people say

This plugin helps to substantially optimize page speed - something that is often neglected. Asset CleanUp helps to unload unused JS/CSS files on specific pages or page templates. By unloading those, you can increase the homepage speed 2-3 times which is huge.

This is, hands down, the best plugin I've ever used for improving site speed. I went from a dismal average of 43 on mobile to 95 on most pages instantly. That range varies, of course, but many of my page speeds for desktop are at 100!

  • The plugin can force re-compression of uploaded JPEG images and convert PNGs to JPEG

What people say

This plugin automatically decreases image size drastically. It also converts png images to jpeg unless if png image has a transparency layer. It compresses all the images automatically during upload. You don't have to take care of anything. Just imagine having a 5mb image, what it does to your site's speed is just beyond speaking.
Dipesh Purohit, Blogger

8. Optimole

"Optimole is the all-in-one solution to all of your image optimization needs."


Key features

  • Smaller images. Same quality
  • Fully automated; set and forget
  • Supports all image types
  • Supports both Retina and WebP images

What people say

It's an image optimization plugin that feels like it was designed by Apple. The image compression and lazy loading features are great, but it's really the on-the-fly image resizing that makes it amazing.
