# 🚀 Speed up

{% hint style="info" %}
**Who can use this feature?**

Speed up is available on the Pro and Expert plans.
{% endhint %}

### What is Speed up?

Speed up turns on the optimizations your store needs — like faster images, smarter loading, and lighter code — without you touching any code.

You have two options:

* **Self-optimize** — flip on the optimizations you want. Available on **Pro** and **Expert**.
* **Speed up expert** — let our specialist do it for you. Available on **Expert** only. See **Speed up expert**.

### Why use Speed up?

* **Faster load times** — quicker pages mean lower bounce rates and better conversions.
* **No code required** — turn optimizations on with a toggle; the app handles the rest.
* **Pick what you need** — enable individual optimizations à la carte, mobile and desktop.
* **Safe to apply** — work on a theme duplicate and publish only when you're happy.
* **Two ways to optimize** — do it yourself, or hand it to a specialist on the Expert plan.

### ⚙️ How to use Speed up

#### Step 1: Open Speed up

Go to **Speed up**.

#### Step 2: Check your speed score

Check your current speed score on the left. Switch between **Mobile** and **Desktop** to see how your store performs on each.

#### Step 3: Review your Audit summary

Turn on the features you want. Locked features show an **Upgrade** link.

**Available on Pro and Expert:**

* **Lazy load (images)** — loads images only when customers scroll to them.
* **Instant page** — pre-loads pages the moment someone hovers a link.
* **Asset image optimization** — shrinks the images in your theme.
* **Lazy load (iframes and videos)** — defers heavy embeds like YouTube and Maps.
* **Preconnect** — gets a head start on external resources.
* **Font swap** — shows text right away instead of waiting for fonts to load.
* **Page loader** — keeps your layout steady while the page loads.

**Available on Expert only:**

* **Minify CSS and JS** — strips junk from your code.
* **JS deferral** — holds back non-essential scripts until customers interact.
* **Critical CSS** — loads only what's needed to show your page first.
* **HyperSpeed** — pushes hidden scripts to the back of the line.

#### Step 4: Apply your changes

Click **Speed up now** and pick how to apply changes:

* **Duplicate current theme** *(recommended)* — works on a copy. Your live store stays safe.
* **Select theme from library** — applies straight to a chosen theme.

#### Step 5: Let it run

Wait while the app works through each task. If anything fails, click **Refresh** to try again.

#### Step 6: Preview and publish

Preview the duplicate to make sure it looks right. When you're happy, publish it.

### 📌 Merchant Notes

* Edited your theme later (new pages, templates, or apps)? Just click **Speed up now** again to re-apply.
* **Duplicate current theme** is the recommended option — it keeps your live store safe until you publish.
* Locked features show an **Upgrade** link; some optimizations are **Expert-only** (Minify CSS/JS, JS deferral, Critical CSS, HyperSpeed).
* If a task fails during processing, click **Refresh** to retry it.
* Prefer hands-off? See **Speed up expert** to have a specialist do the work for you.
