Document Translation in 6 Steps
Import your document, choose your settings, and get a professional translation. Supports TXT, Markdown, DOCX, PDF, and ZIP files up to 2 million characters.
Document to be translated
PDF, DOCX, TXT or MD files, e.g. an English PDF file to be translated into German
Choose Import Method
Click 'Text Import', 'DOCX Import', or 'PDF Import', or simply drag & drop your file.
Drag & Drop
Drop your file anywhere on the page. We'll detect the format automatically (TXT, MD, DOCX, or PDF).
Configure Options
Choose your target language, translation mode, and optional glossary for consistent terminology.
Translation in Progress
Watch the progress bar. Large documents are processed in chunks for reliability.
Review & Export
Review your translation, then export as DOCX, Markdown, or copy to clipboard.
Images Preserved
Images from DOCX and PDF files are extracted during import and restored during DOCX export.
ZIP Import: Markdown with Images
Have a Markdown file that links local images, e.g. from a Pandoc-based workflow (document.md + media/image_1.jpg)? Since a browser can't reach files sitting next to an uploaded document, pack them together into a single ZIP archive — the Markdown file at the top level and its images inside a media/ folder — and drop the ZIP onto TranslateFlow like any other file.
We unpack it, translate the text, and keep the images linked so they appear correctly in your exported DOCX or Markdown — no manual re-inserting needed. This also means a Markdown-with-images ZIP exported from TranslateFlow can be re-imported later, e.g. to translate it into another language.

Choose the right mode for your content. Our AI adapts its approach based on your selection.
Standard
Best for documents & non-fiction
Accurate, precise translation that preserves the exact meaning. Perfect for business documents, technical texts, and factual content.
Creative / Poetic
Best for literature & artistic texts
Preserves style, rhythm, and emotional impact. Prioritizes how the text feels over literal accuracy.
Culturally Adapted
Best for localization
Adapts idioms, references, and cultural elements to the target audience. Makes content feel native, not translated.
Example: German → English
"Das ist nicht mein Bier."
"That is not my beer."
"That's none of my concern."
"That's not my cup of tea."
