Check GZIP Compression

This online tool will check if GZIP compression is enabled for your website. GZIP compression can save 50% to 80% bandwidth, significantly improving your website's loading speed. When GZIP is enabled, files are compressed on the web server before being sent to the visitor's browser. The browser then automatically decompresses the files, allowing them to be displayed quickly. This compression and decompression process is highly efficient, taking only a fraction of a second, and is seamless and imperceptible to the end user. By reducing file sizes, GZIP not only speeds up page load times but also enhances the overall user experience and can lead to better search engine rankings due to improved site performance.

How to Add GZIP Compression to Your Server

Enabling GZIP compression on your server is a straightforward process that can greatly improve your website's performance by reducing file sizes and speeding up load times. Here’s how you can add GZIP compression to different types of servers:

Apache Server

Enable mod_deflate Module: Ensure that the mod_deflate module is enabled. You can do this by adding the following line to your Apache configuration file (httpd.conf or .htaccess):
```
LoadModule deflate_module modules/mod_deflate.so
```

Configure Compression: Add the following lines to your Apache configuration file to specify which file types to compress:

<IfModule mod_deflate.c>
  AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css
  AddOutputFilterByType DEFLATE application/javascript application/json application/xml
  BrowserMatch ^Mozilla/4 gzip-only-text/html
  BrowserMatch ^Mozilla/4\.0[678] no-gzip
  BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
  Header append Vary User-Agent
</IfModule>

Nginx Server

Enable GZIP Module: Ensure the GZIP module is enabled by adding the following configuration to your nginx.conf file:

gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
gzip_proxied any;
gzip_vary on;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_min_length 256;

Restart Nginx: Apply the changes by restarting Nginx:
```
sudo systemctl restart nginx
```

Microsoft IIS Server

Open IIS Manager: Go to the IIS Manager and select your site.
Enable Compression: Under the "Compression" section, enable both "Static Compression" and "Dynamic Compression".

Edit Configuration: If necessary, you can manually edit the web.config file to include:

<system.webServer>
  <urlCompression doStaticCompression="true" doDynamicCompression="true" />
  <staticContent>
    <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />
  </staticContent>
  <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
    <dynamicTypes>
      <add mimeType="text/*" enabled="true" />
      <add mimeType="message/*" enabled="true" />
      <add mimeType="application/javascript" enabled="true" />
      <add mimeType="*/*" enabled="false" />
    </dynamicTypes>
    <staticTypes>
      <add mimeType="text/*" enabled="true" />
      <add mimeType="message/*" enabled="true" />
      <add mimeType="application/javascript" enabled="true" />
      <add mimeType="*/*" enabled="false" />
    </staticTypes>
  </httpCompression>
</system.webServer>

By following these steps, you can enable GZIP compression on your server, resulting in faster load times and an improved user experience for your website visitors.
