PDF Translator Tool

This tool translates PDF documents between languages while preserving layout and formatting where possible. Intended users include researchers, editors, localization teams, legal/compliance professionals, and students who need multilingual PDFs without manual reflow. Example: upload a 12-page English research paper, choose English to Spanish, and obtain a translated PDF with headings, tables, and figures kept in place.
Domain capabilities center on content extraction, translation, and layout reassembly. Required features: secure PDF ingestion, source/target language specification, translation pass, and downloadable translated PDF with preserved structure. Optional/advanced features: OCR for scanned PDFs, glossary/term mapping, translation memory, batch translation, and metadata retention.
Inputs include input_pdf (PDF file, required), source_language (ISO code, required), target_language (ISO code, required), ocr_enabled (boolean, optional), glossary_terms (list of terms, optional). Outputs include translated_pdf, translation_report, language_detected, status, and total_pages.
The tool uses a two-stage pipeline: content extraction and structure analysis, then translation with layout-aware reassembly. For scanned content, OCR extracts text prior to translation, and formatting heuristics map fonts, spacing, and tables to the translated output. Glossary terms ensure consistent terminology.
Error handling covers invalid PDFs, password protection, missing inputs, and unsupported languages. OCR may fail on poor scans; in such cases translation proceeds with best-effort layout. It supports ISO codes, UTF-8, and locale-aware formatting where available.
