Compress Served Files by MIME Type There are a number of file types we know we want compressed on the way out, and with mod_deflate, we can direct the server to do so:

.htaccess - Compress Served Files by MIME Type.htaccess

<IfModule mod_deflate.c>

    # Compress all output labeled with one of the following MIME-types
    # (for Apache versions below 2.3.7, you don't need to enable `mod_filter`
    #  and can remove the `<IfModule mod_filter.c>` and `</IfModule>` lines
    #  as `AddOutputFilterByType` is still in the core directives).
    <IfModule mod_filter.c>
        AddOutputFilterByType DEFLATE application/atom+xml \
                                      application/javascript \
                                      application/json \
                                      application/rss+xml \
                                      application/vnd.ms-fontobject \

                                      text/xml
    </IfModule>
