How to Speed Up a Website on Webflow (Speed Optimization)

A fast website keeps visitors engaged and helps them convert. A slow one increases bounce rate, damages your rankings on Google, and lowers the overall trust in your brand.
Optimizing speed is especially important if you work with animations, custom code, or large assets - all of which can impact Webflow website speed.

‍

Large images are the #1 reason behind Webflow performance issues. Luckily, Webflow provides built-in responsive image scaling - but you still need to prepare your images properly.

Best practices

• Export images in modern formats (WebP or optimized JPG).
• Keep hero images under 250–350 KB.
• Compress everything before uploading (TinyPNG, Squoosh).
• Use SVG for icons and logos.
• Lazy-load non-critical images.

Example

If your homepage features a full-width photo, compress it from 2.5 MB to 300 KB and export as WebP.
Result: instant Webflow speed optimization without changing the design.

‍

Beautiful animations are great, but too many will slow the page down.

Tips

• Remove unused interactions in the Interactions panel.
• Avoid complex animations on mobile.
• Limit “scroll into view” triggers - they can slow rendering.
• Keep animations simple and short.

Animations that run constantly (e.g., looping background elements) can cause Webflow speed issues, especially on older devices.

‍

Every external script adds loading time. Many slow Webflow websites contain unnecessary tracking codes, chat widgets, or old scripts.

How to clean it up

1. Audit your project settings → Custom Code.
2. Remove scripts you don’t actively use.
3. Load heavy scripts only on specific pages.
4. Use “async” or “defer” attributes for better Webflow performance optimization.
5. Replace third-party widgets with native Webflow features when possible.

Webflow automatically minifies CSS & JS, generates responsive images, and uses AWS hosting. When used properly, this alone can significantly increase Webflow page speed.

Checklist

• Enable CSS minification
• Enable JS minification
• Enable HTML minification
• Use Webflow’s built-in CDN
• Keep your class structure clean

These settings help with Webflow page speed optimization and reduce file sizes automatically.

‍

Custom fonts can easily add 300–500 KB to your page load.

Font rules

• Use 1–2 font families max.
• Keep weight variations minimal (e.g., Regular + Bold).
• Host fonts locally via Webflow for faster delivery.

This alone can have a noticeable impact on Webflow website speed.

Large CMS lists can add unnecessary load to your page.

How to manage it

• Limit items per collection list (6–12 is ideal).
• Paginate long lists instead of loading everything at once.
• Use “Load more” with AJAX carefully - it loads scripts on the fly.

If you notice slow dynamic pages, this is often the cause behind your Webflow speed issues.
