PolyglotPDF is a Python-based multilingual eBook and PDF translation tool that preserves original layouts while translating, supporting both digital and scanned PDFs via OCR. It offers a web UI, online and offline translation via LLM APIs (DeepSeek, GPT-4o-mini, Qwen, Doubao) and traditional services (DeepL, Bing, YouDao), and handles math formulas and tables.
Use cases
- translate a pdf document to another language while keeping the original layout
- translate scanned pdfs with ocr
- translate ebooks in any format preserving formatting
- translate academic papers with math formulas and latex
- batch translate large pdf reports with tables
- self-host a pdf translation web service
- translate pdfs offline without cloud services
When to choose
- you need layout-preserving pdf translation rather than plain text extraction
- you work with scanned pdfs or complex layouts like tables and formulas
- you want a self-hosted tool with a choice of translation backends including LLMs
- you need to translate ebooks in multiple formats beyond pdf
When to avoid
- you only need raw text extraction from pdfs without translation
- you need pixel-perfect handling of complex vector math formulas inside tables
- you require a fully mature, bug-free tool for heavily styled or bold/colored mixed text
- you want a lightweight cli-only one-liner translation utility
