Improving your Webflow site’s performance is essential for faster load times, better SEO, and user experience. Here’s a step-by-step guide to help you optimize your Webflow project.
1. Optimize Image Assets
- Compress all images before uploading using tools like TinyPNG or Squoosh.
- Use WebP format for images where possible for smaller file sizes.
- Enable lazy loading for all images and video embeds by setting
loading="lazy"
. - Use SVGs for icons and simple graphics instead of PNGs or JPEGs.
2. Use Global Swatches and Utility Classes
- Reduce redundant CSS by using global color swatches and consistent utility classes.
- This minimizes CSS generation and improves render performance.
3. Limit Fonts and Font Variants
- Stick to 1–2 font families and include only the necessary weights (e.g., 400 and 700).
- Remove unused fonts in Project Settings > Fonts.
4. Minimize Custom Code and Third-Party Scripts
- Remove or defer unnecessary custom code snippets and third-party integrations.
- Use async or defer attributes on any external scripts added via Embed elements.
5. Enable Webflow’s Built-In Minify Options
- Go to Project Settings > Hosting and enable:
- Minify HTML
- Minify CSS
- Minify JS
- Use secure frame headers
6. Clean Up Unused Styles and Components
- Manually delete unused classes, interactions, and symbols.
- Use the Style Manager panel to clean up unused definitions.
7. Use Page Load Interactions Carefully
- Avoid overly complex Page Load animations, especially those relying on continuous loops or blocking content visibility.
- Keep animations lightweight and ideally non-blocking.
- Use Chrome DevTools > Lighthouse Audit to analyze performance.
- Address recommendations such as avoiding large layout shifts and reducing unused JavaScript.
9. Use Webflow’s CMS Efficiently
- Limit the number of Collection list items loaded per page.
- Use pagination or filtering to reduce DOM load.
Summary
To maximize your Webflow site's performance: optimize all assets (especially images), minimize fonts and scripts, use built-in minification, and keep interactions lean. Regularly auditing with Lighthouse ensures you’re proactively catching performance bottlenecks.
