Why choose AI Document Translator?

translate documents while keeping formatting

Layout Preservation

Forget the frustration of re-formatting your files after translation. The online doc translator keeps every image, table, bullet point, and chart in its original position. You get a translated document that looks identical to the source, with fonts and styles perfectly intact.

Large Document Context

Standard tools translate sentence-by-sentence, which leads to awkward phrasing and lost meaning. We process your files in large context chunks, analyzing entire paragraphs and document sections. This results in natural-sounding text and consistent terminology across the whole document.

Different File Formats

We handle all your translation needs, from Microsoft Office (Word, Excel, PowerPoint) and PDFs to technical files like JSON, HTML, and XML. We even support specialized formats like SRT for subtitles and XLIFF for professional translation workflows.

100+ Global Languages

Reach a worldwide audience. Our translation AI tool supports over 100 languages, providing high-accuracy translations that respect regional nuances. Whether it is a legal contract in Spanish or a technical manual in Japanese, the quality stays professional.

Secure & GDPR Compliant

Your privacy is a priority. We provide enterprise security with end-to-end encryption and full GDPR compliance. Your sensitive documents are processed safely and are never used to train AI models.

Human-Level Accuracy

Generic AI often struggles with specialized jargon. Our models are tuned for technical, legal, and business domains, so industry-specific terms are translated with the precision of a subject-matter expert. We capture the intended meaning and tone, not just the literal words.

One document translation tool for all your needs

Sales teams and business owners often need to translate high-stakes documents like pitch decks, contracts, and marketing brochures. If you have a 50-page PDF or a complex PowerPoint presentation, you cannot simply copy-paste the text without ruining the design.

Our translation app helps you send professional proposals to international clients in their native language. Your brand looks perfect because every image, chart, and font stays in its original place. It is the easiest way to grow your business globally without hiring a design team to fix your translated files.

Engineers and developers often struggle to translate technical manuals and data files like HTML, XML, CSV, YML, or JSON. The biggest risk is accidentally translating a piece of code, which breaks the file. Our AI translator is "structure-aware," meaning it only translates the human text while leaving the technical code untouched.

This is perfect for companies that need to localize software documentation or help centers quickly. You get accurate technical translations that follow your specific industry terminology, keeping your data files remain 100% functional and ready to use immediately.

For content creators and localization experts, translating video subtitles or app strings is usually a slow, manual task. We support specialized formats like SRT and VTT for video, and XLF or XLIFF for professional translation workflows.

Instead of editing line-by-line, you can translate entire subtitle files in seconds. This allows you to reach a global audience on YouTube or launch your mobile app in multiple countries at once. It turns a week-long localization project into a task that takes just a few clicks.

F.A.Q

Frequently Asked Questions

Upload your file to our online document translator, select your target language, and click "Translate." The translation tool uses layout-aware technology to map the text to its original coordinates, so fonts, images, columns, and tables stay exactly where they were in the original file.

Most tools (like Google Translate or ChatGPT) extract text as a "flat string," losing the document's spatial data. When the text is re-inserted, the formatting collapses. Our translation AI tool analyzes the visual structure of the file first, so the design is protected before the translation even begins.

Yes. We use end-to-end encryption for every upload. Unlike free public translation services, your sensitive business data is never used to train our models and is handled in full compliance with GDPR. All data is processed on servers located in the EU, and we follow strict data-protection standards for storage, access, and deletion. Once your translation is complete and downloaded, you can permanently delete the file from our servers.

Google Translate is designed for short snippets and often loses context over many pages. Our document translator uses "Large Document Context," analyzing entire sections at once. This maintains consistent terminology from page 1 to page 50, resulting in a more polished, professional flow. We translate full documents while maintaining 100% of the original formatting.

We support all major business formats: Microsoft Word (.docx, .doc), PDF, PowerPoint (.pptx, .ppt), and Excel (.xlsx, .xls). We also handle technical and localization formats like HTML, XHTML, TXT, RTF, XML, JSON, SRT/VTT (subtitles), CSV, YML, and XLIFF.

We support over 100 languages, covering 99% of global business communication. This includes major world languages like English, Spanish, Chinese, and German, as well as specific regional dialects and right-to-left languages like Arabic and Hebrew.

Our Large Language models provide "human-level" accuracy by understanding the context and intent of the writing. While AI is now advanced enough for most business and technical uses, we always recommend a quick human review for high-stakes creative marketing copy.

Yes. Our AI Doc Translator is trained on specialized datasets including legal terminology, medical research, and engineering manuals. It understands industry-specific jargon that generic translators usually get wrong.

Most documents are processed in minutes. A standard 20-page PDF usually takes less than 2 minutes. Very large files (100+ pages) may take up to 10 minutes so every page is perfectly formatted.

No! We offer a document translator free trial so you can test our AI translator free of charge before upgrading to a professional plan.
