Practical overview

When it fits

Use it when a scientific PDF needs translation and retaining its mathematical, visual and structural elements matters.

Who it is for

  • Researchers reading papers in other languages
  • Developers building document-translation workflows
  • Teams seeking CLI, GUI, Docker or MCP access to PDF translation

Documented uses

  • Translate scientific PDF documents
  • Preserve formulas, charts, tables of contents, annotations and layout
  • Connect translation workflows to listed services such as Google, DeepL, Ollama or OpenAI
  • Run document translation through local or containerized interfaces
Before you choose

Requirements & limits

The project is documented as open source under the AGPL-3.0 license. The repository documents local Python use, Windows packaging, Docker and online demos; online demo computing resources are described as limited.

  • Whether preserving formulas, charts, annotations and layout is important
  • Which listed translation backend fits the workflow
  • Whether CLI, GUI, Docker, MCP or Zotero integration is the most useful interface
  • Whether the environment can use the documented Python 3.11–3.12 local setup
  • Whether the AGPL-3.0 license fits the intended use

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Pdfmathtranslate with pip and translate a PDF

    Documented command
    pip install pdf2zh

  2. Run pdf2zh document.pdf.

  3. Find the generated files in the current working directory.

Expected outcome

A translated PDF workflow is run from the command line, with generated files placed in the current working directory.

Guide limitations

  • The supplied documentation does not specify backend configuration or output details for a particular document.
