Gzip compression of EOT, TTF, WOFF and WOFF2 fonts and others

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

A computer font is a file containing 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 download speed of one of the sites with the PageSpeed ​​Insights tool, it was reported that Gzip compression was not applied to the file with * .WOFF2 fonts, although it was turned on and configured for a long time.

How to compress plug-in fonts using Gzip, we will describe later in our article.

To date, four font container formats are used on the Internet: EOT, TTF, WOFF and WOFF2 . But unfortunately, as is usually the case, despite the choice, there is no single format that would work in all browsers:

  • EOT is available only in Internet Explorer.
  • TTF is supported in this browser only partially.
  • WOFF is more widely distributed, but it cannot be used in some older browsers.
  • Over support WOFF 2.0 are currently working.

There is another font container format - SVG . But it was never supported in Internet Explorer and Firefox. And now it is no longer used in the Chrome browser.

In this regard, we need to use all these formats so that the page looks the same among users of different browsers.

Continue on compression. Since I have Nginx running as a front-end on the server, and Apache backend, it was enough for me to turn on Gzip only in Nginx. It is included very simply. It is necessary to add a line in the configuration file:

  gzip on; 

Now we will list the pharmacy files 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 here: /etc/nginx/nginx.conf

Restart Nginx for the changes to take effect: nginx -s reload

For more detailed settings of Gzip-compression in Nginx can be found on the official website of Nginx.

In the same file, be sure to check the values ​​of the gzip_types parameter. First of all, it is there that application / font-woff2 is most often not specified, and therefore this font file was not processed by Gzip compression. At the same time, check for the presence 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 if these types are listed in this file. Below I just give the contents of this entire file:
