How to Speed Up Your Wix Site (An Honest Guide)

Here's something you don't often hear: when we scanned 1,432 small-business Wix sites, the median mobile PageSpeed score was 64 — which actually beats the all-sites median of 60. Wix has a long-standing reputation for being slow, but in our data, Wix sites did better than average. That said, 64 still isn't where you want to be — Google considers 90+ "good" — and the typical Wix site we scanned took 7.1 seconds to show its main content, well over Google's 2.5-second target. So there's real room to improve, and the levers are simpler than you'd think.

Why Wix sites are often slow

First, the honest bit: Wix has invested heavily in performance in recent years, and it shows. Wix controls the servers, serves modern image formats automatically, and uses a global network to deliver your site — so a lot of the technical heavy lifting is already done for you. That's why the myth that "Wix is always slow" didn't hold up in our numbers.

When a Wix site is slow, it's usually down to choices the owner made inside the editor, not the platform underneath. Because Wix handles the server and code for you, your main levers are the visual elements you add: oversized images, third-party apps, and heavy animations or video backgrounds. The flip side of Wix doing so much automatically is that a few enthusiastic design choices can undo a lot of that good work.

How to speed up your Wix site

1. Resize your images before you upload them

This is the biggest thing in your control. Wix automatically serves images in modern, efficient formats — but it can only work with what you give it. If you upload a 5,000-pixel-wide photo straight from your phone or a stock library, that's an enormous file being shrunk to fit a small space on screen, and it still weighs your page down.

Before uploading, resize images to roughly the size they'll actually display — a full-width banner rarely needs to be wider than about 2,000 pixels, and a small product thumbnail needs far less. A free tool or your computer's built-in image editor will do it in seconds, and it's the fastest way to shave weight off a Wix page.

2. Remove third-party apps you don't use

Every app you install from the Wix App Market adds its own code to your site — and that code loads whether or not the app is doing anything useful. Booking widgets, chat boxes, review feeds, pop-up tools and social feeds all inject extra scripts that the visitor's browser has to download and run.

Go through your installed apps and remove any you added but don't really rely on. Each one you clear out is less code to load. If two apps do a similar job, keep the one you actually use and delete the other.

3. Go easy on heavy animations and video backgrounds

Wix makes it wonderfully easy to add scroll animations, motion effects and full-screen video backgrounds — and they can look stunning. But they're also some of the heaviest things you can put on a page. A video background in particular is a large file that starts loading immediately and delays everything else.

You don't have to strip your site bare. Just be selective: keep motion for one or two key moments rather than on every section, and consider replacing a video background with a single well-chosen image. Your site will feel snappier and, honestly, often looks more premium for it.

4. Limit custom code embeds

If you've pasted custom HTML or embed code into your Wix site — an external form, a tracking pixel, a third-party widget — each one is an extra request that Wix can't optimise for you. A couple are fine. A dozen start to add up. Keep only the embeds you genuinely need, and remove any left over from things you've since stopped using.

5. Use Wix's built-in optimisation settings

Wix includes site and image optimisation settings that are worth checking are switched on. In your site settings, make sure image optimisation is enabled so Wix can compress and reformat your images automatically. These built-in tools are doing real work behind the scenes — the point is simply not to override them by uploading giant files or piling on apps faster than Wix can compensate.

6. Keep each page focused

Long pages that stack section after section — galleries, feeds, forms, videos and multiple apps all on one page — give the browser far more to load before anything feels ready. On Wix, where you don't control the underlying code, a leaner page is one of the few reliable levers you have. Split very long pages into shorter ones, lead with the content that matters most, and remove sections that aren't earning their place. Your visitors get to your key message faster, and your score benefits too.

How much difference will it make?

Because Wix already handles the technical layers, your gains come almost entirely from images, apps and animations — and those gains can be substantial. A Wix site sitting at our median of 64 can realistically reach the 80s by resizing images and trimming a few unused apps. Reaching a perfect 90+ is harder on Wix than on a platform like WordPress, simply because you don't control the server or the underlying code — but "needs work" to "good" is very achievable.

Keep your expectations honest: you're optimising within Wix's framework, not rebuilding it. For context on what the scores mean, see what a good PageSpeed score looks like, and if your site is slow for reasons beyond Wix's control, our guide to why websites are slow covers the rest.

Check your own Wix site

The quickest way to know what's holding your Wix site back is to measure it. A free scan gives you your real mobile PageSpeed score, your load time, and a plain-English breakdown of which images, apps or effects are costing you the most — so you can spend your effort where it counts. You'll get honest numbers, not a sales pitch.
