Not setting up gzip or Brotli compression

To improve your website’s performance, you should enable compression. Here’s how to set up both Gzip and Brotli compression:

Gzip Compression

For Apache:

Add this to your .htaccess file:

<IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html
    AddOutputFilterByType DEFLATE text/css
    AddOutputFilterByType DEFLATE text/javascript
    AddOutputFilterByType DEFLATE text/xml
    AddOutputFilterByType DEFLATE text/plain
    AddOutputFilterByType DEFLATE image/svg+xml
    AddOutputFilterByType DEFLATE application/javascript
    AddOutputFilterByType DEFLATE application/x-javascript
    AddOutputFilterByType DEFLATE application/xml
    AddOutputFilterByType DEFLATE application/xhtml+xml
    AddOutputFilterByType DEFLATE application/rss+xml
    AddOutputFilterByType DEFLATE application/atom_xml
    AddOutputFilterByType DEFLATE application/x-font-ttf
    AddOutputFilterByType DEFLATE application/x-font-opentype
    AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
</IfModule>

For Nginx:

Add this to your config:

gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
gzip_min_length 1000;
gzip_proxied any;
gzip_comp_level 6;
gzip_vary on;

Brotli Compression (newer, more efficient)

For Apache (requires mod_brotli):

<IfModule mod_brotli.c>
    AddOutputFilterByType BROTLI_COMPRESS text/html
    AddOutputFilterByType BROTLI_COMPRESS text/css
    AddOutputFilterByType BROTLI_COMPRESS text/javascript
    AddOutputFilterByType BROTLI_COMPRESS text/xml
    AddOutputFilterByType BROTLI_COMPRESS text/plain
    AddOutputFilterByType BROTLI_COMPRESS image/svg+xml
    AddOutputFilterByType BROTLI_COMPRESS application/javascript
    AddOutputFilterByType BROTLI_COMPRESS application/x-javascript
    AddOutputFilterByType BROTLI_COMPRESS application/xml
    AddOutputFilterByType BROTLI_COMPRESS application/json
</IfModule>

For Nginx (requires ngx_brotli module):

brotli on;
brotli_comp_level 6;
brotli_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

Testing Compression

After setting up, test with:

• Browser DevTools (check Content-Encoding header)
• Online tools like WebPageTest or Google PageSpeed Insights
