## What it is
RetainPDF is an open-source PDF translation tool that preserves layout, formulas, and document structure, with special support for scanned/image-based PDFs and complex inline formulas. It ships as desktop apps for Windows/macOS/Linux and a Docker-deployable web service with OCR, translation, and typesetting modules.

## Use cases
- translate scientific papers while keeping the original layout
- translate scanned or image-based PDFs
- preserve inline math formulas when translating PDFs
- batch translate technical documentation with custom translation rules
- self-host a PDF translation service for a team via Docker
- compress translated PDFs and control font sizes

## When to choose
- you need layout-preserving translation of scanned PDFs or complex formulas
- you want a self-hosted or API-driven PDF translation pipeline
- you translate scientific or technical documents regularly

## When to avoid
- you only need plain text extraction or translation without layout
- you need a lightweight CLI-only tool
- you require a fully offline solution without any model/API dependencies

## Facets
- artifact type: application
- maturity: active
- function: ocr, pdf, nlp, machine-learning, image-processing
- domain: pdf, files, education
- platform: windows, self-hosted, cross-platform
