Making internationalization/localization in WordPress faster than ever before.
Attention: most functionality of this plugin has been merged into WordPress 6.5! You might not need it anymore.
However, this plugin is still relevant for cases where language packs are not downloaded from WordPress.org but somewhere else, for example if you are developing your own plugins or using commercial plugins.
The Performant Translations plugin converts the translation files of those plugins to the new file format introduced in WordPress 6.5, to really optimize them for speed.
This project uses a new approach to handle translation files in WordPress, making localization blazing fast.

Very helpful! Easy to access and accurate.
Works great. Assisted with the issues, and it’s easy to use.
What this plugin does is amazing! There were some issues that made my website slow. The website achieved a mobile page speed of 52. Blocked display for more than 10 seconds. I don’t have the technical knowledge to fix this in the code. This would have cost me around $600. I found this plugin and all errors were removed from the website with one click. I am incredibly happy with the result. And that with a free plugin! I knew it should be possible. Because I am so happy, I take the paid subscription! Thank you very much!
Browsing the dashboard feels instant snappier, even if your hosting is already fast and performant – it still makes a difference!
I’ve got a multi language site (with WPML) that has a huge performance problem. I was not able to figure out what is actually causing the performance problem, the main problem probably has nothing to do with i18n, this plugin still helps cause it significantely speeds up the translations, leaving the only bottleneck to be the unknown problem.
Many thanks for your efforts!
