How do I translate a PDF for free?

Drop the PDF above, pick your language, and choose Google or Bing as the engine. The free engines run directly in your browser, with no account and no sign-up. You get a live preview and a downloadable translated PDF.

Does the translated PDF keep the original layout?

Yes. In replace mode the original page stays as it is, colours, images, tables and lines, and only the text blocks are covered and redrawn with the translation in place. There is also a bilingual mode that adds a clean translation page after each original page.

What file formats can I translate?

PDF, Word (docx), Excel (xlsx), PowerPoint (pptx), EPUB ebooks, plain text, Markdown, HTML, and the subtitle family including SRT and VTT. Text, Markdown, HTML, EPUB and Word also support a bilingual download with the original and translation together.

Is my document uploaded to a server?

The file itself never leaves your browser. It is parsed locally and only the extracted text is sent to the translation engine, Google or Bing on the free path, or the AI engine you pick. Nothing is stored by default.

Can AI translate the document, not just Google or Bing?

Yes. With the Swiftin browser extension installed and signed in, AI engines translate the rendered preview in context, which keeps terminology consistent across a long document. The free plan includes 50,000 AI tokens a month, and Google and Bing keep working after that, unlimited.

Free engines or AI

Google and Bing are free, unlimited, and need no account, fine for getting the gist of a manual or an invoice. AI translation earns its keep on text with voice: contracts, books, anything with idioms or domain terms, because it reads whole blocks in context so terminology stays consistent. The AI path runs through the Swiftin browser extension and includes 50,000 AI tokens a month on the free plan; when they run out, Google and Bing keep working.
