Why formatting matters in a Word document
A Word file stores the text and the layout as a single unit: paragraphs, bullet lists, tables, heading styles, page breaks and fields. When you copy text out of a document, paste it into an online translator and paste it back, the layout disappears, tables fall apart and the styles no longer apply to the translated text.
For reports, manuals, proposals and client deliverables, the formatting is part of the value. A tool that works on the document structure keeps that layout usable after translation.
- Paragraphs and bullet lists
- Tables and their columns
- Heading styles and document structure
- Hyperlinks and images
- Page and section breaks where the format carries them
What a document translation preserves
Polyglot Tool's Document Translator works on the document file rather than on a copy of the text. It reads each supported element — paragraphs, list items, table cells, headers and footers — translates the text and writes it back into that element inside the original file structure. Headings stay headings, lists stay lists and tables stay tables, using the styles that were already in the file.
Because the text is reconstructed in place instead of the document being rebuilt from scratch, the supported formatting is preserved. Translation can change text length, so a very tight source layout may reflow differently in the translated version. That is an inherent property of translation, not a formatting error.
What a translated DOCX looks like
The excerpt below shows how the same elements behave after an English-to-Spanish translation of a DOCX: content is translated in place, and the structure and styles of heading, list, table and image elements are retained.
How Word translation works in Polyglot Tool
Upload a .docx written in English. The tool analyzes the file first — format, size, approximate word count, source language and selected targets — before translation starts, and it will not start if the document exceeds the limits.
Translation runs on Polyglot Tool servers with open, offline models hosted on its infrastructure. The document is never sent to Google, DeepL, OpenAI or other external translation services, and files are deleted automatically after a short retention period.
- Upload an English .docx
- Review the pre-flight analysis
- Select one to five target languages
- Download each translated document or a ZIP of the completed translations
Target languages and limits
Documents are translated from English. In one operation you can choose between one and five target languages, and each one is processed as an independent job, so a failure in one language never blocks the others.
- Spanish, French, German, Italian and Portuguese
- Up to five target languages per operation
- Up to 10,000 words per document
- Up to 20 MB per document
How to check what was preserved
After translating, open the downloaded DOCX and compare the structure of the translated file with the source. Reopening the file tells you structure and styles survived; a quick diff of the two files confirms which text changed.
Reviewing a machine translation
The translation is automatic machine translation and can contain errors. Review important, legal, medical, financial or professional documents before relying on the translated version.
- Check tables and numbers after translation
- Re-apply any layout the target platform needs
- Keep the original English file as the master copy
Where your document goes
Document Translator has a server-side architecture, unlike Polyglot Tool's SRT and VTT translators, which process subtitle text in your browser. A Word document is uploaded to the Polyglot Tool server for processing, translated with models hosted on Polyglot infrastructure, and never sent to third-party translation services. The temporary files are deleted automatically after the retention period.
Because the architectures differ, the privacy statement for subtitle translation does not apply to document translation. The document itself travels to the server; only the output is delivered back to you.
