Word and DOCX translation

Translate Word Documents While Preserving Formatting

Upload a DOCX, choose target languages, and get an editable Word file.

Get a translated Word file in three steps

01

Upload DOCX

Upload .docx files from Microsoft Word 2007 or later. The source language can be detected automatically or specified manually.

02

Confirm terminology before translating

The system first parses the document and extracts terminology. Full-document translation begins only after you confirm the translations and cost.

03

Proofread and download Word

Review translations online, edit and regenerate as needed, then download an editable translated DOCX.

Structure-aware translation

More than body text extraction—understands Word document structure

SimplifyAI links translatable content with formatting, position, and structure information, then writes translations back to their original locations to reduce reformatting and omissions.

Character and paragraph styles

Preserve formatting such as bold, italics, underlines, fonts, font sizes, colors, highlights, superscripts, subscripts, and paragraph styles during translation.

Tables and cells

Detects translatable paragraphs in tables, writes translations back to the corresponding cells, and preserves the original table structure.

Footnotes and endnotes

Footnotes and endnotes outside the main text also go through the same translation pipeline and are written back to their original note locations when complete.

Comments and comment anchors

Translate Word comments while preserving their start and end anchors in the document for continued team review.

Headers, footers, and text boxes

Covers headers, footers, and floating text boxes that standard text extraction tools can easily miss.

Numbering, table of contents, and links

Preserve bullet points and multilevel numbering, update table of contents text, and retain internal and external hyperlinks.

Embedded Visio graphics

Detects text in embedded Visio graphics in DOCX, writes translations back to VSDX, and refreshes the visible preview.

Cross-script font repair

Adds font slots for target languages such as Chinese, Japanese, Korean, and Arabic to reduce missing glyphs or incorrect fonts in translations.

Translation quality control

Define terminology and requirements before sending the full document

Review every step, from language detection and model selection to term confirmation and cost estimates. You can also go straight to the fully automated translation pipeline.

Pre-translation terminology analysis

AI first extracts key terms and suggests translations. After you confirm, it translates the full document.

Manual glossary and translation requirements

Edit term translations individually, add terms manually, and specify tone, style, and context requirements.

Models and multiple target languages

Choose available AI models for each job and generate versions in multiple target languages from one source document.

Pre-translation confirmation

Review word count, terminology, and cost estimates before translation. You can also skip confirmation and process directly when needed.

Cloud processing for long documents

Long documents are split into batches and translated in the cloud, with progress saved continuously. After submitting, you can close the page and return later to view the results.

Online review and regeneration

Edit translations in your browser and regenerate the DOCX, while keeping file versions from each revision.

Post-translation review

Machine translation is complete, but the workflow is not over

Review source text and translations segment by segment

Filter entries that need review by keyword

Regenerate DOCX after editing translations

Keep revision history and the latest delivered file

Export bilingual Excel or XLIFF files for professional translators

Import external revisions and continue generating the final Word file

Human control

Edit translations in your browser, then generate a new Word file

Translations and source text are aligned by stable document units. After edits, the system writes back to the original DOCX and generates a new version instead of overwriting historical delivery files.

Teams can also export bilingual Excel or XLIFF files, review them in familiar CAT tools, then import them back into SimplifyAI to generate the final DOCX.

Supported documents

Built for complex Word documents in real-world workflows

Contracts and business documents

Process contracts, policies, and internal documents with numbered clauses, headers and footers, comments, and tables.

Research reports and papers

Covers long-form body text, footnotes, endnotes, hyperlinks, chart descriptions, and complex chapter structures.

Product manuals and training materials

Generate multilingual versions while preserving heading levels, lists, tables, and text box structure.

FAQ

Which formatting is preserved when translating Word documents?

SimplifyAI parses the underlying DOCX structure, preserves common character and paragraph styles, and handles tables, footnotes, endnotes, comments, headers and footers, text boxes, numbered lists, tables of contents, and hyperlinks. Document complexity varies, so a final check is still recommended after download.

Are legacy .doc files supported?

Currently, only .docx files based on Office Open XML are supported directly. Please save legacy .doc files as .docx in Microsoft Word or compatible office software before uploading them for translation.

Can I control terminology and style before translation?

Yes. The system first extracts terms and suggests translations. You can edit, delete, or add terms, specify tone, style, and context requirements, then confirm to start translation.

Can I make manual edits after machine translation is complete?

Yes. Edit translations paragraph by paragraph in the online review interface, then regenerate the DOCX based on your revisions. You can also collaborate with external translators through bilingual Excel or XLIFF.

Do I need to stay on the page while a long document is translated?

No. Long documents are split into batches and translated in the cloud, with progress saved continuously. After submitting a job, you can close the page and return to the job list later to view the results or download the file.

Will text in images be translated?

The current public DOCX translation pipeline primarily processes editable text in Word structures and supports text in embedded Visio graphics. OCR translation for text in standard bitmap images is coming soon.

Will mathematical equations in the document be changed?

Content in Word equations (OMML) is not sent for translation and is preserved as is in the translated document. Explanatory text around equations is translated normally.
