Webflow automatically enables GZIP compression for all assets, including HTML, CSS, and JavaScript files. However, if a speed test tool flags missing compression, it may be due to cached files or third-party resources.
1. Verify GZIP Compression
- Use tools like Google PageSpeed Insights, GTmetrix, or WebPageTest to check GZIP compression.
- If results show missing compression, confirm it's for Webflow assets and not third-party scripts.
2. Clear Webflow and Browser Cache
- Publish your Webflow site again to refresh assets.
- Clear your browser cache or use an incognito window to test fresh resources.
3. Check Third-Party Resources
- External scripts (e.g., Google Fonts, analytics, embeds) may not be compressed if the provider doesn’t serve them with GZIP.
- Use a content delivery network (CDN) for non-Webflow-hosted assets if needed.
4. Reduce File Sizes
- Webflow already compresses images and code, but you can further optimize:
- Enable WebP format for images in Webflow.
- Use fewer custom fonts and minimize weight variations.
- Reduce unused CSS and JavaScript from third-party integrations.
Summary
Webflow enables GZIP compression by default, so no additional setup is needed. If a speed tool flags issues, check for cached resources, third-party scripts, or test with another tool for verification.
