What It Does

This plugin allows you to use DeepL translation API to translate posts and pages right from your WordPress Admin.

Adds a translate button to the edit post page and shows current and remaining API usage.

This plugin requires an active DeepL API subscription with access to the API. Please note that DeepL User or Teams plans do NOT include API access. You have to get a DeepL Developer plan (both DeepL API Free and DeepL API Pro work with this plugin).

Want to translate Products, meta fields, or translate in batches? Get the DeepL Pro API plugin.

Please note: the free and the premium version works the same relative to content editors (Elementor, Blocks, etc.). You are free to test this plugin on your website to see if your specific configuration works well with the plugin. We cannot guarantee that all content editors work perfectly with the DeepL API so please test this plugin before buying the premium (you’ll need the premium only if you need extended features like meta translations and batch translations).
