Changing the WordPress site language to any other than English slows down page generation times. A lot. This is caused by the slow and inefficient way of text domain loading. PO and MO files are designed to be used with PHP Gettext-extension. But since it’s an extension, it’s not installed by defalt on very hosting platform. To overcome this barrier, WordPress has re-implemented the whole MO file parsing in PHP, but WordPress’ implementation is quite slow and memory intense.
This plugin replaces the default MO-Reader with another implementation of MO parsing, which is faster than the default one. Only used text domains are loaded (since version 4.6 this is also WordPress’ default behaviour) and from these only used translations are loaded. It also makes use of hash tables included in mo files, which are ignored completely by WordPress’ default implementation. To boost the performance even more, the plugin also caches translations to the object cache, if one is installed. For optimal performance you need a fast object cache backend like Redis, Memcached or APC(u).
Fast Translate is a minimalistic fork of <a href="https://wordpress.org/plugins/wp-performance-pack" rel="ugc">WP Performance Packs</a> localization improvements. <a href="https://wordpress.org/plugins/wp-performance-pack" rel="ugc">WP Performance Pack</a> offers additional control and more optimizations for WordPress performance, e.g. use of PHPs native gettext extension, improved image handling and CDN support.

Loco Translate

must have


Great plugin. Very useful to be able to translate plugins without an external tool like poedit.


Great tool

I'm using it in all one language projects


So easy to translate strings in any plugin or theme! Also big plus for keeping updating plugin instantly, especially with the recent bug in WP 6.7


Outstanding plugin!


We recommend this to all of our clients who ask about translations.



It can even be used to "translate" (alter) default English texts within a plugin/theme too.


Awesome Plugin

Great support!


A must-have plugin for managing the lifecycle of translations in custom plugins and themes. 



There's a steep learning curve to climb when it comes to language and translation management. This plugin helps a lot and works really well.



Also impressed with the speed of response to my help topic. Thanks Tim!


Excellent plugin and support


This is a great tool. I've been using it for years, and it has never let me down.
