35k-star PDFMathTranslate: upload any paper or ebook, get a translated PDF with formulas, figures and layout intact. Pre-wired to AllRouter.

Why use this one

Most PDF translators flatten the document: equations turn into garbled text and two-column layouts collapse into one stream. PDFMathTranslate parses the layout first, so a physics paper still reads like a physics paper.

How to use it

  1. Upload an English paper (PDF) — no page limit for normal papers
  2. Pick a model; DeepSeek is cheapest for bulk pages, Claude reads dense math best
  3. Download the bilingual PDF — formulas, figures and two-column layout stay intact

What it costs

Free anonymous quota to try it. Register (free) for about 15× more. Or paste your own AllRouter key for unlimited use — it stays in your browser and is never sent to our server. Every run shows its exact cost, down to $0.0001.

Questions

Do I need to install Python or Docker?

No. The project normally requires a local Python environment and a model API key. Here it runs on our machine — open it and upload a file.

Is my PDF stored?

The file is processed and returned; we do not build a library of user uploads. For anything confidential, run the project locally — the repo is open source and linked on this page.

What does it cost?

You get a free anonymous quota to try it, and a larger one after registering. Long books consume more tokens than short papers because every page is sent to the model.
