PDFMathTranslate

An AI based PDF translation tool that preserves formulas, charts, tables of contents, and annotations, with Google, DeepL, Ollama, and OpenAI among its translation backends.

PDFMathTranslate is a PDF scientific paper translation tool that preserves formatting. The README says it keeps formulas, charts, table of contents, and annotations intact, supports multiple languages, and can be driven as a command line tool, an interactive user interface, or through Docker. The project appears as an EMNLP 2025 demo. Python is the primary language, the license is AGPL-3.0, and the homepage is pdf2zh.com.

Executing the translation command produces two files in the current working directory: a translated document and a bilingual document. Google is the default translation service, with more services available. The repository description names Google, DeepL, Ollama, and OpenAI among the supported backends.

Advanced options cover local files, online files, entering the GUI, partial document translation, source and target language settings, translation service selection, multi threading, and an output directory. The README points to an advanced usage document for the full list of each option, so the main file stays short.

Version 2.0 moved to a new repository and the official release has been published. Public free services online are recommended for people who do not want to install anything, including an immersive translate option and a demo hosted on ModelScope. Docker images exist, with a GitHub Container Registry alternative. The README also warns that users in specific regions may hit network difficulties loading the AI model, documents an environment variable workaround, and covers other issues in an FAQ. A Windows tip suggests installing a runtime if a downloaded file will not open.
