Overview

RetainPDF is an open-source, layout-preserving PDF translation tool built for scientific and technical documents. It handles scanned and image-based PDFs with OCR, renders complex inline formulas correctly, avoids translating code, and keeps the original layout, tables, and structure intact. It ships as a full-stack project (frontend/backend separated) with an API for automation, Docker deployment for teams, desktop apps for Windows, macOS, and Linux, and continuous PDF compression optimizations.
