How to Enable Gzip Compression in WordPress

by admin

Used by more than half of all websites, Gzip Compression remains popular today.

According to W3Techs.com, 55.3% of all websites, including major sites like Microsoft.com, Github.com, and Apple.com, use gzip compression technology.

As the name suggests, Gzip is a compression technology. This technology compresses static files on the server side and sends them to browsers. Browsers will then automatically decompress and display these compressed files. This process makes the web page open faster.

Enabling it is extremely easy if you know which web server you have.

1. How Enable Gzip Compression in Apache

In order to enable gzip compression on Apache servers, the mod_deflate module must be installed. Almost all hosting companies install the mod_deflate module on their servers, so you don’t have to worry.

You need to add the following code into the .htaccess to enable gzip in Apache servers.

# BEGIN Gzip

AddType x-font/woff .woff
AddType x-font/ttf .ttf
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/x-font-ttf
AddOutputFilterByType DEFLATE x-font/ttf
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE font/opentype font/ttf font/eot font/otf

# END Gzip

Note: If gzip is not active despite following the instructions above, we recommend contacting your hosting company.

2. How Enable Gzip Compression in Nginx

On servers using Nginx, gzip compression cannot be activated automatically, so you have to enable gzip compression manually.

You need to add the following code into the /etc/nginx/nginx.conf to enable gzip in Nginx servers. Do not add anywhere. You should add it inside the http {} section.

gzip on;
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types image/svg+xml text/plain text/html text/xml text/css text/javascript application/xml application/xhtml+xml application/rss+xml application/javascript application/x-javascript application/x-font-ttf application/vnd.ms-fontobject font/opentype font/ttf font/eot font/otf;

After adding the gzip compression lines, save and close the config file and restart NGINX with the command.

sudo service nginx restart
