Theme & Front-End Speed

Fast themes, fixed at the code level.

Most speed problems live in the theme: bloated Liquid, render-blocking scripts, oversized images. We fix them at the source, so your store loads fast for real instead of masking the problem with another plugin.

Why are Shopify themes slow? Most theme slowdowns come from bloated Liquid, render-blocking scripts and oversized images. We fix these at the code level so pages paint faster, instead of adding another plugin on top.

What we do

Engineered for real speed

We fix theme bottlenecks at the code level so pages paint faster, without breaking your design or features.

Liquid Refactoring & Render-Blocking

We clean up bloated Liquid and templates and stop scripts and styles from blocking the page, so your content starts appearing sooner.

Images & Critical CSS

We modernise and compress images (WebP/AVIF), add lazy loading, and inline the critical CSS the first screen needs, so the page paints fast on the first visit.

CDN / Storefront Renderer

We make sure your store takes full advantage of Shopify's CDN and Storefront Renderer, so pages are built and delivered as fast as the platform allows.

Frequently Asked Questions

How do you find out whether my Shopify theme is slowing the store down?

We inspect the theme's Liquid templates, scripts, styles and images, then measure how they affect loading and rendering. The audit separates theme bottlenecks from problems caused by apps or other third-party code.

What do you change in a Shopify theme to improve speed?

The changes depend on the audit. They may include simplifying Liquid code, reducing render-blocking scripts and styles, optimising images, and improving how essential content is loaded.

Will theme optimisation change how my store looks or works?

The goal is to improve performance while preserving the storefront's design and features. We review affected components and test them after changes rather than treating a faster page as successful if something has broken.

Do I need to replace my current theme?

Not necessarily. We first look for bottlenecks that can be fixed in your existing theme. If a theme has deeper limitations, we can explain those findings before recommending a larger change.

Can image optimisation affect product image quality?

Images should be sized and delivered appropriately for where they appear. We aim to reduce unnecessary image weight while checking that product photography still looks right on the storefront.
