DeepL Pro is a subscription service that provides access to the full capacity of DeepL's AI translation technology. DeepL Pro is intended for software developers who would like to develop new apps and services with our API, professional translators who would like to incorporate DeepL's translations into their workflow, and corporations who require fast, accurate translations to conduct business.

DeepL Translator is a machine translation service that produces translations of unprecedented quality. A subscription to DeepL Pro includes improved web translation features.

We’re always on the lookout for new talent. Current job vacancies can be found here. If you don’t see the role you’re looking for, but you think you’ve got the skills, please contact us!

We have several DeepL Pro plans that offer flexible access to our services. A basic overview of what DeepL Pro plans include is as follows:

• The guarantee that your texts are not stored for any purpose
• Unlimited use of the Web Translator (except DeepL API plan)
• Fully-editable document translations
• Integration of DeepL's translation engine into CAT tools (Advanced and Ultimate plans)
• Access to the DeepL API (DeepL API plan only)

Please also consult our Pricing page for further information.

DeepL Pro supports translations in the same language combinations as available on DeepL Translator. There are currently 110 possible combinations between English, German, French, Spanish, Portuguese, Dutch, Italian, Polish, Russian, Japanese, and Chinese. Further languages will become available in the near future.

DeepL Pro offers options for both individuals, teams, and developers and is available through several different plans. Prices depend on how much you would like to translate, how many team members you have, and how (or if) you would like to integrate DeepL's translation technology into various platforms. For more detailed information, please also consult our Pricing page.

DeepL Pro plans are available on both monthly and annual payment schedules. The minimum duration of any plan is one month (one billing period). In the case of annual plans, the billing period is equal to one year. You can cancel your subscription at any time before the end of the current billing period. The contract then runs until the end of that billing period and will not be renewed.

Annual plans are paid up front, after the conclusion of your free trial period (with the exception of Ultimate plans). With monthly billing, payment is due at the beginning of each monthly billing period.

Please note: The DeepL API plan is available only on a monthly basis. The base price (€4.99) and usage-based charges are paid at the end of the billing period. Two exceptions to this rule apply. If, in the first billing period of a new DeepL API subscription, costs (base price plus usage) reach €50, DeepL reserves the right to charge the credit card provided by the customer immediately, as a guarantee of payment. Subsequently, when costs exceed €500 within one billing period, this amount is charged each time it is reached. At the end of the billing period, any outstanding costs will be charged as normal.

Yes. We offer several plans and the flexibility to customize those plans and switch between them, should your needs change. After signing up for a DeepL Pro plan, options to change your plan can be found on your Account page. Upgrades take place immediately, whereas a switch to a more limited plan will take effect at the end of the current billing period.

We accept payment by credit card and direct debit (SEPA). Team plans billed annually may also be paid by bank transfer. We accept euros (EUR, €), American dollars (USD, $), and Canadian dollars (CAD, $).

Annual billing offers the greatest savings; monthly billing offers the greatest flexibility. If you opt for annual billing, the full year is paid up front, after the conclusion of your free trial period (with the exception of Ultimate plans). With monthly billing, payment is due at the beginning of each monthly billing period. However, this does not apply to the DeepL API plan, which is billed at the end of each monthly billing period. Both payment schedules allow you to modify or cancel your plan.

Microsoft Word (.docx) and PowerPoint (.pptx) files can be translated using the free version of DeepL Translator. DeepL Pro subscribers can also translate plain text (.txt) files, and the DeepL API plan also enables translation of HTML (.htm and .html) files. Note that files must be uploaded one at a time. For further information about which file formats can be translated in CAT tools, please contact the CAT tool provider.

After signing up for a DeepL Pro plan, you always have the option to add more document translations to your plan. As with other changes to your plan, you can do this from your Account page.

You can change your subscription from an individual plan to a team plan at any time. You also have the option to set the number of users on your team plan as you like. You can make these changes on your Account page. Please note: The minimum number of users on a team plan is three.

DeepL Pro does not store the texts from your requests or their translations. Only metadata about the request (e.g. the time of the request, the IP address, or the number of translated characters) are saved for billing and statistics purposes. Please see the DeepL Pro Terms & Conditions for details regarding data privacy.

As a company based in Germany, all our operations comply with European Union data protection laws. Read more about the advantages offered by European Union data protection standards here.

With DeepL Pro we add another layer of data security. We guarantee DeepL Pro subscribers that all texts are deleted immediately after the translation has been completed.

In order to enjoy the benefits of DeepL Pro while using our online translator, you need to be signed into your account.

You can cancel your subscription at any time.

To do so, log into your DeepL Pro account. Select My Account from the menu, then select Account. Cancel your subscription by clicking Terminate subscription. Your DeepL Pro subscription will then cease to be active at the end of the current billing period. You can continue to use DeepL Pro up until that point in time.

There are several plans that allow people to use DeepL Pro within CAT tools. Both the individual and team versions of the Advanced and Ultimate plans allow DeepL Pro users to use DeepL’s translation technology within CAT tools. Please note that these plans do not include access to the DeepL API for integration in applications other than CAT tools.

Below is a list of CAT tools that allow DeepL Pro integration:

• SDL Trados Studio 2017 and 2019
• memoQ 8.7.6 or higher
• Déjà Vu X3 or higher
• Wordfast Classic, Wordfast Anywhere, & Wordfast Pro 5.7 or higher
• Across Translator Edition and Across Language Server
• Memsource
• Weblate

This list is far from exhaustive. If your favorite CAT tool is not listed here, please contact the provider to see if they can create a plug-in to allow you to integrate DeepL Pro!

The DeepL Pro plug-in may only be supported in certain versions or editions of the CAT tool providers’ products. In order to find out more about plug-in support, please contact your CAT tool provider’s customer service.

You will be able to use the web translation service with the same advantages as integrating DeepL Pro into CAT tools; no restriction of text length, full document translation, and excellent data protection, as your clients' texts will never be stored.

A DeepL Pro subscription allows you to use DeepL's technology to translate between the following languages in CAT tools: English, German, French, Spanish, Portuguese, Dutch, Italian, Polish, and Russian. Further languages will become available in the near future.

Important: Should you encounter difficulties when using DeepL Pro with memoQ 8.7.6, please make sure that your plug-in is up to date, either by installing updates automatically, or by checking for memoQ updates manually.

The DeepL API plan is specifically designed for software developers to build new software and applications on top of our translation technology. Please note that the DeepL API plan is the only plan that allows this. Also, the DeepL API plan does not allow you to use DeepL Pro within translation software.

The DeepL API plan offers you the option to set a limit on the number of characters that you can translate per month and thereby control your maximum costs. You need only activate Cost Control in your Account settings. Simply click "Change cost control settings," tick the checkbox to enable, and enter either the maximum number of characters or the maximum amount and apply the changes. You can make further changes at any time.

The Authentication Key is a code that enables DeepL Pro subscribers access to our API. The Authentication Key looks similar to “df4385c2-33de-e423-4134-ca1f7b3ea8b7”. You can find your unique Authentication Key in your DeepL Pro Account page.

DeepL Pro can automatically recognize the language of a text. The reliability of the result increases with the length of the text, and short texts can sometimes lead to incorrect results.

If you specify the language of the text in a query, the DeepL Pro translator always uses that language. If you know the language of the source text, you should use the source_lang parameter to specify the corresponding code.

With tag handling enabled, you can translate sentences with tags (e.g. XML tags). The translation engine will map the tags onto the appropriate location in the target sentence as well as it can. Please consult the API documentation for detailed information on types of tags supported.

Please note that the DeepL API does not currently translate whole XML files.

The sentence splitter splits the source text into individual sentences. However, if you only send single sentences to the API, you can disable the sentence splitter so that the text is translated as one sentence.

Yes, this is actually advisable for long texts, since the length of URLs is limited by the web server.

This error occurs if the API URLs are too long and is due to a length limit of the web server. You can avoid this error message by using a POST request instead of a GET request.

In a POST request, you do not send the data in the URL, but rather as data in the body of the request. There exist libraries for most programming languages to support the easy sending of POST requests.

However, if you have to create a POST request yourself, you should consider the following points:

1. Use POST as the request method.
2. Set the Content-Type request header to application/x-www-form-urlencoded.
3. Set the Content-Length request header to the number of bytes in the request body.
4. Insert your translation request parameters into the request body. The parameters should be URL-encoded using the UTF-8 character set. In other words, the body looks exactly like the query part of the equivalent GET-request (the characters after the question mark of a GET-request).
5. Use the same URL as for GET-requests, but without parameters, i.e. https://api.deepl.com/v2/translate.

The request https://api.deepl.com/v2/translate?auth_key=00000000-0000-0000-0000-000000000000&text=This%20is%20a%20Test.&target_lang=EN should look like this as a POST request:

POST /v2/translate HTTP/1.1
Host: localhost
Content-Type: application/x-www-form-urlencoded
Content-Length: 87

auth_key=00000000-0000-0000-0000-000000000000&text=This%20is%20a%20Test.&target_lang=EN
    

The DeepL API plan places no limit on the amount that you can translate, and counts your usage by the character. The characters counted are those in the source text, i.e. the original text you would like to translate.
One character corresponds to one unicode code point, where a single character can consist of several bytes. For example, the character é is represented as two bytes in UTF-8. However, DeepL only considers this as one character. Invisible characters such as spaces, tabs, line feeds, etc. are also counted.
