Absolute-to-Relative URLs


If you were to use this on a website like http;//, you would get results like these:

    • Before: http;//
    • After: ../another-test/#anchor
    • Before: http;//
    • After: /wp-content/themes/twentyten/style.css
    • Before: https;//
    • After: https;//
    • Before: http;//
    • After: //
    • Before: ../../../../../../../../#anchor
    • After: /#anchor
    • After ($output_type=1): ../../#anchor

All string parsing. No directory browsing.

If you’re looking for a plugin that will automatically convert all URLs on your WordPress site, instead check out my other plugin, WP-HTML-Compression.
Before you copy this code and add it into your own, keep in mind that there will probably be future updates. Keeping the code within an installed plugin will make sure that you’re notified.


  1. Download the plugin (zip file).
  2. Upload and activate the plugin through the “Plugins” menu in the WordPress admin.


Why isn’t this automatic?

Check out WP-HTML-Compression instead.

How does this work?

Just use absolute_to_relative_url($url).

Will this plugin work for WordPress version x.x.x?

This plugin has only been tested with versions of WordPress as early as 3.2. For anything older, you’ll have to see for yourself.
