Translatable Files: Optimizing Translation Costs and Timelines

When it comes to translation, not all files are created equal. The choice of format can significantly impact the translation process, affecting both costs and delivery times. This article explores the differences between the main types of translatable files, focusing on those that facilitate translators’ work and those that require an additional Desktop Publishing (DTP) step.

Before diving into the various file types and formats, an important disclaimer is needed: all files are translatable. Simply put, some are better suited to translation than others.

Translatable Files: The Best Formats

Files such as Word, Excel, PowerPoint, and certain InDesign formats are among the most preferred by professional translators. Their structure allows easy access to text and efficient management of linguistic resources.

1. Word (.doc, .docx): Word documents are one of the simplest and most widely used formats globally, not just for translation. Most Computer-Assisted Translation (CAT) tools can handle these files seamlessly, allowing the original formatting to be maintained. This means the text can be translated directly, significantly reducing costs and timelines.
2. Excel (.xls, .xlsx): Excel spreadsheets, often used for data, lists, or tabular content, are also easily managed by CAT tools. The cell structure helps isolate the text to be translated, avoiding interference with numerical data or formulas.
3. PowerPoint (.ppt, .pptx): PowerPoint presentations can be translated while preserving the original formatting and layout. This is especially useful for corporate or academic presentations, where visual impact is crucial. The ability to work directly on the slides eliminates the need for pre- or post-translation adjustments, further reducing costs.
4. InDesign (.indd): Some InDesign files can also facilitate translation work. If prepared correctly, these files can be imported into CAT tools, maintaining the design and layout elements intact. This process makes it easier to translate brochures, catalogs, and other marketing materials while keeping costs down.

Files That Require DTP

Not all files, however, are so straightforward to handle. Some formats require an additional Desktop Publishing (DTP) process to ensure that the translated document retains the original visual quality. Among these, PDF files are the most common.

1. PDF: PDF files are widely used for final documents due to their portability and ability to preserve formatting across devices. However, translating a PDF can be complex—or at least more complex than editable files mentioned earlier. Often, the text in PDFs is embedded as an image or distributed in a way that prevents easy extraction. This means the text must be extracted manually or via Optical Character Recognition (OCR) software before it can be translated. After translation, the document must be reconstructed, requiring DTP expertise to maintain the original layout. This extra step, of course, increases both translation time and cost.
2. Images (JPEG, PNG, TIFF): Images containing text, such as JPEG, PNG, or TIFF files, present an even greater challenge. The embedded text must be extracted and translated separately, then reintegrated into the image. This requires not only translation but also graphic skills to recreate the image with translated text, preserving the original appearance.
3. Other Formats: Other files that may require DTP include graphic formats such as Illustrator (.ai) or Photoshop (.psd). Although they contain text, these files require post-translation graphic editing to ensure that the design and translated text are harmoniously integrated.

Conclusions

The choice of file format for translation is not a trivial detail. Files created in software such as Word, Excel, PowerPoint, and in some cases InDesign can greatly facilitate translators’ work, reducing associated time and costs. On the other hand, files such as PDFs, images (JPEG, PNG, TIFF), and other graphic formats require an additional DTP process.

Understanding these differences can help optimize the translation process, ensuring a high-quality final result that aligns with the set timelines and budget.
