Debutify is a Shopify theme optimized for all niches and designed to boost the conversions and overall performance of your website or online store. It’s, in fact, considered the highest converting Shopify theme that you can get for free and that’s also suitable for all types of products and industries.

Why are Some Themes Fast, and Some Slow?

Faster themes have a handful of characteristics that give them an advantage over slower ones: 

  • They contain less code, which means they get processed faster on the server. 
  • Their file size is smaller, which makes them easier to download. 
  • They don’t rely on jQuery JavaScript library.
  • They have cleaner CSS and inline CSS so the site can render faster.

All of these characteristics enable the server to download and render the site faster from the server, also taking the load off the browser so it can assemble the page easily and in less time. 

Slower themes usually need to download more JavaScript and frequently use off-shelf libraries and APIs, not necessarily optimized for speed such as Google Maps APIs and Google Fonts. 

When setting up your Shopify store, one of the first decisions you need to make is choosing your theme. Of course, the theme of your choice should be customizable, have a beautiful and responsive design, and simple navigation, among other things, but one feature that’s often overlooked is theme speed

Did you know that a site’s bounce rate worsens with each second the page takes to load? 

The average bounce rate of pages that take 2 seconds to load is 9%, whereas the average bounce rate of pages that take 5 seconds to load is 38%. Let’s give you some more eye-opening statistics related to page speed. 79% of online consumers won’t return to a slow-loading site, 46% of mobile users say that slow load time is what they dislike the most when browsing the web, and even a 100-millisecond delay in load time lowers conversion rates by 7%! 

Given that page-speed is a crucial part of user experience and an important ranking factor, you need a fast and reliable theme for your online store. This is why we chose and reviewed the 8 fastest Shopify themes that can give you a better spot in search results but also bring you more conversions and revenue.

What Should I Consider When Choosing a Shopify Theme?

Before we go over the themes one by one, let’s see the key features that the best and fastest Shopify themes should include.

Website Speed

As we already mentioned, site speed influences your Google rankings, and with that, your visibility, conversation rates, and user experience. The faster your site is, the better ranking it will have and the more customers it will bring.

This is why in this article we included only the fastest Shopify themes available in 2021, while also paying attention to design and flexibility.

Design and Flexibility

Speed is not the only precondition for a successful online store, as the store’s design is another important factor. That is why in our quest for the fastest Shopify themes, we were looking for those with appealing designs that online consumers will appreciate. And not only that, but we also ensured that the themes are flexible and customizable so you can show your creativity and create the online store just as you’ve envisioned it.

What Makes a Theme Fast?

Well, a fast theme is a small theme. A fast theme has a clean CSS and fewer CSS files that are easily downloadable when the page loads. There is also less pressure from the javascript of the browser which makes the page display much faster.

A fast theme essentially has a fast rendering speed. Shopify, as one of the fastest e-commerce platforms, also offers hosting services with good infrastructure that contributes to the speed of your online store. That is why the fastest Shopify themes are quick to download and render very fast.


Turbo's landing page

We can’t mention Flex without mentioning Turbo, its more affordable counterpart. Turbo is another super popular theme choice created by the award-winning team of developers called Out of the Sandbox.

Why is it so popular, you might ask? Well, the name of the theme says it all! Turbo offers amazing speed and performance power for your Shopify online store. As feature-packed as it is, this theme is perfect for online stores of all sizes. If you have a shop with a huge inventory, you will feel the benefits of the super-fast loading speed and caching functionality that will dramatically improve your user experience.

Sport and Ludicrous Speed Modes

How about a Shopify theme that comes in two-speed modes? Well, Turbo is built and optimized for speed, but when it comes to the performance setting, it enables you to choose between two options: Sport and Ludicrous.

In Ludicrous mode, the page preloading uses advanced methods to attempt to predict the next page the user visits and starts loading that page in the background. However, certain third-party apps might crash with this mode, which is why you can also choose Sport. This mode offers all the performance capabilities of the Turbo Shopify theme, without the preloading page technology but with seamless integration with third-party apps.


Turbo comes in six urban and beautiful designs named by some extraordinary cities like Portland, Florence, Dubai, Seoul, Tennessee, and Chicago. These designs are packed with useful features that can be operated with intuition and simplicity, leaving you to showcase your creative and selling capabilities.

Frequently Asked Questions

What else is important when it comes to site speed?

Theme speed is pretty important when it comes to improving the overall site speed, but of course, it’s not the only factor. Other important factors in this equation are: 

  • Hosting provider (hosting quality);
  • Hosting location;
  • The use of CDN (Content Delivery Network);
  • The overall size of the page – page weight in MB.

How do I test my site speed?

You can try our free speed testing tool Once you put your site in there, it will give you a more detailed overview of what you need to improve and provide you with advice on how to make your site load faster. 

Does theme speed impact SEO?

The answer is a definitive yes. Site speed is considered a ranking factor for SEO and the theme speed has a big impact on the site speed. 

In our years of experience optimizing sites for speed, we’ve come to the conclusion that the size of each page in megabytes (or the page weight) is a key factor here. So, a site that has a lot of pages, especially ones that go over the 3-5mb limit, will most likely not rank well. 

Some of the techniques you can implement for making your pages weigh less are: 

  • Image optimization;
  • Use of lazy loading;
  • Use of next gen webp file formats.
