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 scans your site and provides one-click fixes to speed up WordPress in a flash.

You’ll get faster loading pages, higher search rankings (SERP) and PageSpeed scores, and happier visitors with Hummingbird’s WordPress speed optimization. Optimizing the speed of your site has never been easier!

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.

Optimização de recursos

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.

Integração Cloudflare nativa

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.

Our Membership gives you access to Hummingbird Pro – which features automated scanning, uptime monitoring, enhanced minify compression (with 2x the regular optimization), CDN hosted minification – alongside Smush Pro image optimization, all our premium WordPress plugins, and 24/7 WordPress support.

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 está a ficar mais inteligente em cada actualização. Hoje já se tornou tão bom que me obrigou a remover gigantes plugins de cache e optimização como WP Super Cache and WP Sweep porque agora Hummingbird inclui todas essas funcionalidades – mas de um modo ainda mais impressionante.” – swagatam1975


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


“Apenas criei um site WP que parece um saco inchado e depois de configurar Hummingbird e deixá-lo fazer o seu trabalho, o site na verdade está rápido — mas rápido do que tem direito…Estou impressionado.” – Cacarr

Perguntas frequentes

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.

Hummingbird funciona com Cloudflare?

Sim! Hummingbird está construído para tirar todas as vantagens das funcionalidades Cloudflare. Apenas adicione a sua API para começar.

Hummingbird funciona com WooCommerce?

Sim! Hummingbird funciona muito bem com plugins ecommerce como WooCommerce or MarketPress. Para obter melhores resultados, quando configurar a cache de página, siga as opções recomendadas por WooCommerce. Hummingbird irá excluir o carrinho, as páginas de minha conta e finalização de compra para manter o conteúdo dinâmico.

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?

Hummingbird is a great free plugin, and Hummingbird Pro is even better. You can find out more here.

Alguém me ajude! Activei a Optimização de Recursos e danificou o meu 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 🙂

I've spent way too much time trying optimization plugins, both paid and free. I've installed Hummingbird on 3 sites instead of a paid product and the performance is very good.
