DeepL API translation plugin

by malaiac

Description

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.
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’re 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)

Installation

Upload plugin folder to the /wp-content/plugins/ directory
Activate the plugin through the ‘Plugins’ menu in WordPress
Enter your API key in the Settings/DeepL settings page

Screenshots

To be used with an active DeepL plan WITH API access

Good plugin

By leonliang on January 15, 2024

It's simple to use. I used it to translate my content with DeepL api. Thank you to the author.

Decent, but not good when making constant edits.

By GeddeDev (ggedde) on January 9, 2024

This translates your content within the Admin panel, but it forcefully translates your text in the Admin panel, meaning you have no way of seeing the original text you wrote. There is an option to translate it back, then make edits, then run the translation again, but that will eat up your Deepl API costs and add extra time to your project. This can make adding new text to an existing page or making edits extremely difficult.

This does not give you any type of help when organizing your site or pages for translation. You will still need a separate plugin for that or WP Multi site and get help setting that up with a language switcher, etc. This can be an advantage if you want to control that yourself and all you need is a translator.

Good work

Good work. It is a plugin that has been giving me very good service for years and is very well maintained and updated by its developer.

Works fine for me

Great Work!

Awesome plugin

By jonathanbertholet on August 17, 2023

Love it! Just not always clear how much can be translated in one go.

Would be good to have the option of splitting up the page's content into multiple pieces to translate if it's too much to do in a single time.

Translates only title and excerpt, not the content

By Sven Woltmann (svenwoltmann) on June 24, 2023

I've activated all three checkboxes in the settings for title, excerpt and content.

When I click the translate button, it shows "This post has been translated." ... but only the title and the excerpt are translated, not the body.

Although the title is only 25 characters and the excerpt is 225 characteres, it removed 1,000 characters from my DeepL credit. The remaining 750 characters are not the content, the content has 90,000 characters.

Using WordPress 6.2.2 with the (now default) Gutenberg editor.

I have to say thank you to the developers!

By Ilias Antonopoulos (elias69) on January 30, 2023

This plugin is a life saver for me. A big thank you to the developers!

It works without problems and uses DeepL to translate a post, page, CPT (Custom Post Type) to the selected language.

I've tested it both with Free and Pro API DeepL accounts.

I use it to translate a website with hundreds of posts, pages, CPTs, from Greek to English.

Any limitations is not for this plugin to blame. The translation quality is based on DeepL's quality.

In my case, after translation, I have to check the translation and apply changes. But even this way, this plugin saves so much time and money.

You have to be fluent in the translated language output to spot and perform changes. This is a DeepL's issue, but I am sure that will be improved in the future.

This plugin is a life and time saver as it helps minimize the time to translate content.

Thank you Developers!!

wp:heading partially translated

By moeee on October 26, 2022

Hi, first this plugin saved me so much time, exactly what i was searching for. I noticed that the  translation was alway partially translated in the html "text" , e.g.  <h2 id="h-buongiorno-a-tutti">Buongiorno a tutti</h2>  Translated from It to eng become  <h2 id="h-buongiorno-a-tutti">good morning everyone</h2>  How this work? in that case if not corrected the heading translation, search engine crawlers are going to see the old untraslated language?

Great plugin

By doriusinio on October 7, 2022

Great plugin thanks but please you should add a feature to hide my API keys as people could steal my credits if they hack one of my website.

Perfect plugin, just what I needed.

By DesertTh0rn (marmotmarketing) on April 27, 2022

Thank you for this great plugin, it does exactly what I need in my workflow! Saves a lot of time.
