Using the cPanel Optimize Website feature

The Optimize Website feature in cPanel allows you to improve your site’s performance by enabling Apache’s mod_deflate module. This compresses content before sending it to visitors’ browsers, reducing load times and bandwidth usage.

Why Use Optimize Website?

• Speeds up page loading by compressing text‑based content (HTML, CSS, JavaScript).
• Reduces bandwidth consumption.
• Improves user experience and SEO rankings.

Steps to Enable Optimization

1. Log in to cPanel.

2. On the Tools page → Advanced section, click Optimize Website.

3. Under Compress Content, choose one of the following options:

   • Disabled → Turns off compression.
   • Compress All Content → Compresses all files before sending them to visitors.
   • Compress the specified MIME types → Compresses only selected file types.

4. If you choose Compress the specified MIME types, enter the MIME types you want to compress (e.g., text/html, text/plain, text/css, application/javascript).

5. Click Update Settings.

Note

• Compression applies only to text‑based content. Images, videos, and PDFs are not compressed by mod_deflate.
• Over‑compression may cause issues with certain file types. Use specified MIME types for more control.
• If your site uses a caching or CDN service (like Cloudflare), check compatibility before enabling compression.
