Gzip-compression of EOT, TTF, WOFF and WOFF2 fonts and other

Gzip-сжатие шрифтов EOT, TTF, WOFF и WOFF2 и других

A computer font is a file that contains a description of a set of alphabetic, numeric, service and pseudographic characters used to display these characters (in particular text) by the program or the operating system.

When developing Internet projects, plug-in fonts are used. However, after testing the speed of loading one of the sites with the PageSpeed ​​Insights tool, a message was issued saying that the file with * .WOFF2 fonts does not use Gzip compression , although it has long been enabled and configured.

How to compress the connectable fonts using Gzip, we will discuss later in this article.

To date, the Internet uses four formats of font containers: EOT, TTF, WOFF and WOFF2 . But, unfortunately, as usual, despite the choice, there is no single format that would work in all browsers:

  • EOT is available only in Internet Explorer.
  • TTF is only partially supported in this browser.
  • WOFF is more common than others, but it can not be used in some older browsers.
  • Over the support of WOFF 2.0 are working now.

There is another format for the font container - SVG . But it was never supported in Internet Explorer and Firefox. And now it ceases to be used in the Chrome browser.

In this regard, we need to use all these formats to make the page look the same for users of different browsers.

Let's continue with compression. Since I have Nginx as the frontend on the server and the Apache backend, it was enough to enable Gzip only in Nginx. It turns on very simply. You need to add a line in the configuration file:

  gzip on; 

Now, we list the file pharmas that we need to compress through Gzip:

 application / atom + xml
 application / javascript
 text / javascript
 application / json
 application / ld + json
 application / manifest + json
 application / rss + xml
 application / vnd.geo + json
 font / ttf
 application / x-font-ttf
 application /
 application / font-woff
 application / font-woff2
 application / x-web-app-manifest + json
 application / xhtml + xml
 application / xml
 font / opentype
 image / bmp
 image / svg + xml
 image / x-icon
 text / cache-manifest
 text / css
 text / plain
 text / vcard
 text / vnd.rim.location.xloc
 text / vnd.wap.wml
 text / vtt
 text / x-component
 text / x-cross-domain-policy; 

In Ubuntu Server, this file is located here: /etc/nginx/nginx.conf

For the changes to take effect, restart Nginx: nginx -s reload

More detailed settings of Gzip-compression in Nginx can be found on the official site of Nginx.

In the same file, be sure to check the values ​​of the gzip_types parameter. First of all, it usually does not specify application / font-woff2 , and therefore this font file was not processed by Gzip-compression. At the same time, check the availability of other font formats:

 application / x-font-ttf
 application /
 application / font-woff
 application / font-woff2

That's not all. Now open /etc/nginx/mime.types and check whether these types are listed in this file. Below, I will simply list the contents of this entire file:
