8 Best Free WordPress Minify Plugins (2022)

wordpress minify plugins

We spent many months testing the best free WordPress minify plugins to bring you the ultimate eight.

Make your website FASTER!

Remember, not all modification tools keep their word.

Unfortunately, we found many poor performers. (They just didn’t do a good job at minimizing CSS, JS & HTML.)

But the ones that are here are not.

Minification is a great way to speed up your site. It won’t necessarily be a big BOOST, but better a little faster than not. (Google likes speedy sites & blogs!)

Note: Larger/heavier websites can see more improvement than lighter.

Make it FAST LIKE Sonic!

2. Fast Velocity Minify (Advanced)

The moment I saw many positive reviews about the Fast Velocity Minify plugin, I knew I need to test it out.

Even though this is a more ADVANCED modification tool, I still had no issues using it.

In fact, I even reach out to the author for some custom work, and he was happy to help me out.

Note: The minifcation happens on the first, un-cached request.

The other pages that require the same CSS and JavaScript will then use the generated static CSS/JS file.

If LiteSpeed Cache was the ideal companion for beginners, then Fast Velocity Minify is perfect for experts.

Hummingbird is (BY FAR) the best name for a WordPress minify plugin. That’s the first cool thing about it.

And the second – which is even better than the first – is the one-click minification function.

Minify scripts and styles like a champ even if you don’t really know what you’re doing.

Hey, we’ve all used a minification plugin for the first time once. You’re in GOOD HANDS with Hummingbird.

But its features go way beyond that, including cache, deferring CSS, lazy loading, etc.
