Translate PDF
Translate a PDF, page by page, into any major language. You pick the AI provider, you bring the key — imisspdf never sees the file.
Unlike our other tools, this one sends your document content to the AI provider you choose (OpenAI, Anthropic, Google, or your own Ollama server). Your key and your file content never touch our servers — the request goes directly from your browser to the provider you pick. Don't use for documents that can't go to any third party.

What "Translate PDF" means here
Translate PDF takes the text of a PDF document and rewrites it in a target language using a large language model. We extract the text page-by-page, send each page individually to the AI provider you choose, and stitch the translations back into either a clean Word document or a plain text file. The original PDF stays where it is on your computer; what comes back is editable text in the new language.
We deliberately do NOT try to overlay translated text onto the original PDF layout in this version. Translated text length varies dramatically across languages — a short English sentence can become much longer in German or much shorter in Chinese — and overlaying breaks the original\'s visual rhythm. A Word document lets the new text reflow cleanly, which is almost always what people actually want.
Why BYOK
A typical online "translate PDF" service uploads your file to its server, runs the translation there, and emails you the result. That route works fine for non-confidential content but it inserts a third party into the loop. We side-step this: you bring an API key from OpenAI / Anthropic / Google AI Studio, or run Ollama locally for zero-cloud translation. Either way, imisspdf is not in the request path.
Privacy & security
Your key lives only in localStorage. Document text is extracted locally and sent directly from your browser to the AI provider. imisspdf doesn\'t proxy, log, or store anything related to the translation. To wipe saved keys, click "Forget all keys" or clear site data.
Frequently asked questions
No. The page extracts the PDF text locally and sends each page directly from your browser to the AI provider you pick. Your key sits in localStorage — it never reaches us.
Honesty over false promises. Translated text length swings wildly — a 5-word English line can become 2 ideograms in Chinese or 12 words in German. Overlaying that on the original PDF without re-typesetting produces an ugly broken-looking PDF. We give you clean translated text or a Word document instead, so you can re-typeset cleanly. A future "best-effort PDF overlay" mode is on the roadmap.
Yes. We translate page by page (rather than dumping the whole document into one call). This keeps us comfortably inside model input limits, lets you see progress as the document moves through, and means a single bad page doesn't take the whole document down — that page is marked but the rest still translate.
Any language the underlying AI supports — which is most major world languages. The dropdown lists the 12 we currently localise the site UI in, but you can also type a free-form language name like "Vietnamese" or "Tagalog" by switching to the custom option.
Not directly — there's no text to extract from a scan. Run it through our OCR tool first to produce a text-bearing PDF, then translate that.
