Hummingbird – Optimize Speed, Enable Cache, Minify CSS & Defer Critical JS


Hummingbird makes your website faster and optimizes site performance by adding new ways to boost Google PageSpeed Insights with fine-tuned controls over file compression, deferring CSS and JavaScript styles and scripts, minify for CSS and JS, Lazy Load integration, and world-class caching.

Hummingbird is brought to you by the WordPress speed specialists that created Smush image optimization, now active on more than +1 million websites. Get the complete speed boost with Hummingbird and Smush.

If PageSpeed Insights is making these speed recommendations Hummingbird can help:

  • Enable text compression – Use gzip to make your site fly.
  • Preconnect to required origins – Use Hummingbird to establish earlier connections.
  • Preload key requests – Prioritize resources based on order.
  • Avoid enormous network payloads – Consider Lazy Load for comments or breaking up smaller posts.
  • Use efficient cache – The Hummingbird Cache suite offers effective browser cache for caching any site.
  • Fix your JavaScript execution time – Deliver smaller JS payloads, preload JS, and defer JS.
  • Minify CSS – Strip unused code from your CSS.
  • Minify JavaScript – Speed up the time it takes to parse your JS files.
  • Eliminate render-blocking resources – Move critical CSS and JS inline and defer all non-critical JS/CSS.
  • Defer unused CSS – Defer the loading of CSS not used for above-the-fold content.
  • Lazy Load offscreen images (Smush free integration).

Hummingbird Features to Speed Up WordPress

Scan and One-Click Fix

Hummingbird is a WordPress speed optimization plugin. It will scan your site, find files that are slowing it down, and provide tips and fixes for making your site run at top speed.

Hummingbird even has one-click improvements like a full cache suite, one-click minify for styles and scripts, and deferring CSS and JS for quickly optimizing performance. What could be easier!

World-Class Caching

You’ll get a world-class caching suite, including full-page, browser, and Gravatar cache.

Make your site load even faster with Hummingbird’s complete set of cache tools that give your visitors a faster browsing experience. Including full-page, browser and Gravatar caching.

Asset Optimization

Did you know that the more files you add to your site’s header, the slower it will load? With Hummingbird, you can easily customize the load position of your CSS, JavaScript (defer CSS and Javascript) and other files to increase your page speed.

Quickly reorder, compress, and reposition files with Hummingbird’s minification feature. But play carefully – minification is a powerful tool (though if you need it, you can reset any changes you make in one click).

Transfer Data at Top Speed With GZIP

Hummingbird has GZIP powers to make sharing your site more efficient.

Sending zipped files is faster and can save you money on hosting. And don’t worry about setup, send Hummingbird instructions with the click of a button and she’ll handle the rest.

Built-in Cloudflare Integration

Hummingbird can be used to control your Cloudflare browser cache settings as well! Simply add your Cloudflare API key and configure away.

Fully Compatible With Smush Image Optimization

You can complement Hummingbird’s WordPress speed optimization features with our award-winning sister-plugin Smush image optimization. Smush compresses your images, giving your site less to load – and thus a faster load time. Hummingbird + Smush integrate perfectly together, and are the perfect match to speed up WordPress.

Compress, optimize (optimise), and fix PageSpeed performance with properly sized images, lazy load, next-gen WebP convert, image formatting, and more.

Faster Websites Rank Higher, Convert Better

Every millisecond counts: your visitors expect an ever-faster website, with a page load time of under two seconds expected – and the norm. If visitors don’t get that on your site, they will leave.

If you’re running a business website or eCommerce store, that means if your website does not load quickly, you will lose sales.

Hummingbird is here to help you; it’s a one of a kind WordPress performance optimization plugin that can make your site run at superspeed, for free!

You get our WordPress performance optimization suite, which includes minification and GZIP for small page sizes, full caching for faster loading, and integration with Cloudflare’s browser cache, and our sister-plugin Smush image optimization.

Hummingbird is built with ease-of-use in mind; it makes your WordPress site faster, but it’s also fast to set up. You can scan your site and implement recommended changes in one-click, getting a fast site in mere minutes.

All the above is free and will speed up WordPress for you. If you need the very fastest WordPress site, you should get a WPMU DEV Membership.

What do People say About Hummingbird?


Hummingbird is so easy to use. I thought it wouldn’t change my speed much because I already made improvements. I ran the scan, it gave me recommendations, I pushed a button to apply them and it made my site even faster!” – Camilo


“Hummingbird is getting smarter with each update. Today it’s become so good that it forced me to remove giant cache and optimization plugins like WP Super Cache and WP Sweep because now Hummingbird includes all those features – but in a more impressive way.” – swagatam1975


Hummingbird took me from 32 to 84 on Google page speed plus made my site 50% faster on GTmetrix!” – Nicolas


“I just built a real bloated sack of crap of a WP site, and after configuring Hummingbird and letting it do its thing, the site is actually fast — much faster than it has any right to be…I’m impressed.” – Cacarr

Întrebări frecvente

Do I need Hummingbird if I already have caching like WP Rocket or W3 Total Cache?

Yes! Of course, our cache suite is more than enough, but if you already use WP Rocket or W3 Total Cache, the special monitoring tools Hummingbird offers still make it worth it. To ensure compatibility, only activate overlapping features in one of the plugins.

Does Hummingbird work with Cloudflare?

Yes! Hummingbird is built to take full advantage of Cloudflare features. Just plug in your API to get started.

Does Hummingbird work with WooCommerce?

Yes! Hummingbird works great with ecommerce plugins like WooCommerce and MarketPress. For best results, when configuring full-page cache, follow the WooCommerce recommended cache settings. Hummingbird will exclude the cart, my account and checkout pages to keep content dynamic.

Why is my WordPress slow?

There are plenty of factors involved in why you’d have WordPress slow. Hummingbird’s scanning and one-click fixes can work out why your site is slow, and with one click, speed up WordPress for you. Easy peasy!

What’s the difference between Hummingbird and Hummingbird Pro?

The free Hummingbird plugin is a powerful suite of WordPress speed optimization features! You can deliver big improvements in your page speed in mere minutes using our one-click implementation of recommended fixes. Some of the reviews above show you the results you can get.

Hummingbird Pro is available as part of the WPMU DEV Membership, and adds automated scanning, uptime monitoring, enhanced minify compression (with 2x the regular optimization), and CDN hosted minification. This will make your site even faster.

Membership also gets you all our premium WordPress plugins, including Smush Pro, for the very best image optimization with image resizing, lazy load, and next-gen WebP convert, and 24/7 WordPress support. Hummingbird is a great free plugin, and Hummingbird Pro is even better. You can find out more here.

Somebody help! I turned on Asset Optimization and it broke my site!?

Asset Optimization is a great way to speed up your site but moving, combining, using minify, and rearranging CSS and JavaScript (.JS) files can also mess with styling and break functionality. We recommend making incremental changes and testing your site as you go so you can undo the changes if something breaks. And remember, don’t panic. If something goes wrong you can start over with the click of a button 🙂

Without comparison! The best! It has amazing tools that no other plugin has.

1. Does not reduce page load. My GTMetrix page size went up to 25MB with this on. It is now 953KB with W3 Total Cache. 2. Causes endless 503 errors because of the asset optimization settings. Website wouldn't update, kept crashing. Elementor would not update my page. 3. Messes up the CSS intermittently on mobile. I've had a lot of headache figuring out what I was doing wrong before I realized this is incompatible with my Elementor site. If you're running Elementor, be warned. Asset Optimization seems inviting but will break your site completely. Have migrated to W3 now.

I've very happy with Hummingbird and I recommend it. I got a good increase in overall speed. I like that you can select individual CSS or JavaScript components and combine them and move them to the end of the page. Very nice for the landing page where many components are not needed at all. However it's a little thin in the caching options (at least the free version) so I use WP Rocket as well and let it control the caching. Hummingbird combined with WP Rocket has given me a nice performance boost. I can still do more with Hummingbird because there are a lot of detailed options.
