About formatting
Styles, headings, tables, images, headers, footers and numbering all survive. The one thing that does not: if part of a paragraph was bold or coloured — a few words in the middle of a sentence — that paragraph comes back in a single style. There is no way to know which words in a translation correspond to the ones that were bold in the original.
Häufige Fragen
Is my document uploaded to your server?
No. The .docx is opened in your browser, which pulls the text out of it. Only that text — not the file — is sent to be translated, and the translated document is put back together on your device.
That is a real distinction rather than a slogan: the text does leave your browser, because something has to translate it. What never leaves is the file, with everything else in it — the images, the metadata, the tracked changes, the author name, the comments.
Will the formatting survive?
Almost all of it. The translation is written back into the original document rather than into a new one, so styles, headings, tables, images, headers, footers, page breaks and numbering are all exactly as they were.
The exception is formatting that applied to part of a paragraph. A sentence with two bold words in the middle comes back with the whole sentence in one style, because a translation has a different word order and there is no way to know which words the bold belonged to.
Why only five pages?
Because translation costs money to run, and this is the free tier. A page here means about 1,800 characters, which is roughly a full page of prose. Paid credit for longer documents is not available yet.
Can it do PDFs?
Not yet. A PDF has no paragraphs to write into — text sits at fixed positions on the page — so translating one means rebuilding the document rather than editing it, and translated text is a different length to the original. That is being worked on separately.
How good is the translation?
It is done by a language model with the whole paragraph in front of it, which is why it handles sentences that Word has split across several pieces. It is good enough for understanding a document and for most everyday use. It is not a certified translation, and for anything legally binding you want a human.
