Why high-quality automatic document translation matters for global businesses

Accurate, automatic document translation is so valuable because the task of translating documents is so complicated. Translating text is just one part of the process. It’s just as important to preserve the way those words are set out in document designs. 

Every element is crucial to the end result:

• Paragraph ordering and numbering in a contract
• Annotations on a diagram
• How words and images work together in a brochure or a PowerPoint slide
• Timings of video subtitles

Translating documents by copying and pasting the words and then flowing them back into designs is hugely time-consuming. And it comes with increased risks. 

Pasting legal copy into the wrong paragraph can result in serious legal consequences. Websites break when the format of HTML documents goes awry. When dealing with multiple languages manually, the risk of these mistakes grows.

The ability to translate documents accurately and efficiently while avoiding these issues is crucial for international businesses. That’s why DeepL is committed to innovating and enhancing the document translation experience, as well as our language models’ accuracy.

How DeepL Translator creates a superior document translation experience

We’ve developed techniques and processes that adapt designs to work with translated copy and carefully preserve original document formatting. They give you greater control over translated documents, cut the need for extensive corrections, and avoid tedious hours fixing layouts. 

DeepL Translator supports a wide range of business file types, including these:

• Office documents: Word, Excel, and PowerPoint files
• Web and structured content: HTML code and XLIFF data files
• Media and localization assets: SRT subtitle files
• Complex layouts: PDF documents with detailed images and designs

For pioneering aviation electronics firm JAE, this type of trustworthy document translation has proven a game changer for internal communication. 

“We can now send the documents immediately without waiting for the translation,” explains Takashi Ito, general manager of JAE’s Information Security Management Office. “In the past, this used to take a week to be done manually. DeepL has reduced the number of occurrences where we had to send materials but were too busy to do so.”

The value of DeepL Translator’s document translation comes from multiple factors:

• Quality of the translations themselves
• Accurate capture of formatting and design
• Features that let businesses leverage document translation in the way that works best for them 

These strengths create a faster, safer way to localize critical files at scale.

5 practical ways to use DeepL Translator for document translation 

Here are five ways you can use DeepL Translator to transform document translation. Each example reflects real use cases, from PDFs and contracts to technical manuals and marketing assets.

Your teams can work faster without sacrificing accuracy or layout control.

1. Drop PDF files directly into the document translation window without copying, pasting, or using OCR tools

Most documents translated with DeepL are PDFs. Our document translation solution extracts text from PDFs automatically.

You don’t need to worry about copying and pasting or using separate optical character recognition (OCR) tools to grab copy. You simply drag your PDF file into the document translation window to get started.

2. Generate translated documents in their original formatting

DeepL Translator’s document translation supports all the most important business formats, including these:

• DOCX, PPTX, and XLSX from Microsoft
• HTML code
• XLIFF data files
• Simple TXT and SRT subtitles

In all these formats, you generate a translated document in its original formatting with elements like layouts, paragraph numbering, footnotes, and timecodes preserved.

Crucially, it does the same for PDF documents’ visual layouts, retaining original design and formatting copy to work with. It maintains integrity even when the length of translated text changes. As a result, you can rapidly localize even external marketing collateral.

3. Save time by translating multiple documents at once

If you have a set of documents to translate, you can save time by uploading them as one batch. You can do this even if the documents are in different formats and you need to translate them into different languages. 

When you upload your document batch, you can specify the language you want to translate each document from and to. Alternatively, you can let Translator detect the languages for you.

4. Apply glossaries to keep document translations consistent

Once you’ve uploaded a document or set of documents, you can also apply a glossary to your translations. This allows you to translate your brand vocabulary and specialist technical terms consistently across all the documents you’re translating. 

DeepL automatically reflects the tone of your original documents. If you prefer, you can also choose to specify a formal or informal tone for your translations.

5. Edit translated documents so that you stay in control

When translating individual documents, you can use Edit mode to generate a preview of your translated copy alongside the original. Then, you can refine it using the dictionary or alternate features. 

Once you’ve finished editing, you can download the formatted document with your changes or discard them and revert to the original translation.

When translating PDFs, Translator gives you the option of downloading your translation as a Word document or a fully designed PDF. Because Translator preserves designs accurately, the PDF option is usually the most efficient. 

With this option, it’s easy to make minor font and text box position adjustments using Adobe Acrobat editing tools. If you have complex layouts and want greater design control, you can download Word documents for designers to reflow into layouts.

How DeepL document translation delivers both accuracy and control

In all areas, DeepL document translation delivers accurate, nuanced copy translations alongside accurate layout and formatting reproductions.

It also gives you the control you need to ensure the final result delivers what you need. That’s the key to transforming document translation, saving time, enabling better communication, and accelerating productivity for localization teams. 

It’s about having the confidence that a document reads the right way in every language you need.
