Combine JS


WordPress plugin that combines, minifies, and compresses JS files. The JS files that this plugin combines and minifies must be enqueued by using wp_enqueue_script. The plugin combines and minifies JS and writes the output into files in the uploads directory. This plugin uses jsmin.php – PHP implementation of Douglas Crockford’s JSMin. This plugin combines all local JS files into a single file and includes the file in the footer of the theme (requires wp_footer being used in your theme files). Also see the companion plugin, Combine CSS.

Features include:

  • option to change the JS domain if a CDN is used
  • option to change how often JS files get refreshed
  • option to exclude certain JS files from combining
  • option to turn on/off GZIP compression
  • option to move all enqueued JS files to the footer of the site
  • option to turn on debugging


  • This is a screenshot of the Combine JS settings page.


  1. Upload combine-js folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress


JS is not working properly after activating the plugin. What can I do?

You can debug the plugin by activating the debug option on the settings page and reviewing the server’s error log for details. You can try excluding certain JS files from getting combined to see if that fixes the issue. The plugin will not minify any javascript files that have ‘-min’ in the file name, so if you can narrow the issue to a single file, try renaming it with -min and see if that fixes the issue.

Thought Google Page Speed is saying the JS files could be compressed more.
