GZIP Compression Frequently Asked Questions

What you need to know about GZIP compression.

What is GZIP compression?

GZIP is a compression algorithm used on web servers. It shrinks your web pages by 70-90%, which speeds up page loads and reduces bandwidth usage.

Why is GZIP important?

With GZIP compression enabled, page load times drop significantly. This improves the user experience and has a positive effect on your Google rankings, since Google favors fast-loading sites.

How do I enable GZIP?

Apache (.htaccess):
AddOutputFilterByType DEFLATE text/html text/css application/javascript

Nginx:
gzip on; gzip_types text/html text/css application/javascript;

Which files should be compressed?

HTML, CSS, JavaScript, JSON, XML and other text-based files should be compressed. Files that are already compressed, such as images (JPEG, PNG, WebP) and PDFs, should not be compressed again.
