Should I use brotli or gzip compression for better performance?
Asked on Sep 18, 2025
Answer
Using Brotli compression generally provides better performance than Gzip due to its higher compression ratios, which can lead to faster page load times by reducing the size of transmitted files.
Example Concept: Brotli is a modern compression algorithm that typically achieves better compression rates than Gzip, especially for text-based files like HTML, CSS, and JavaScript. It is supported by most modern browsers and is particularly effective for HTTPS connections, offering both faster downloads and reduced bandwidth usage.
Additional Comment:
- Brotli is more CPU-intensive than Gzip, so consider server resources when implementing it.
- Ensure your server and CDN support Brotli to take full advantage of its benefits.
- Fallback to Gzip for older browsers that do not support Brotli.
- Test your site with tools like Lighthouse to measure the impact of compression changes on performance metrics.
