A zero‑data‑retention policy ensures that original and translated files are deleted within 24 hours, providing strong privacy protection for users in academia, marketing, e‑commerce and finance. Unlimited free translations, parallel processing of up to two tasks, and optional OCR for scanned PDFs make Belin Doc a practical choice for multilingual document workflows. The tool’s accurate layout retention, formula recognition and image translation further reduce post‑processing effort, positioning it as a reliable solution for anyone needing seamless, cost‑free document translation.

Belin Doc operates as a free web‑based AI document translation service that accepts files via drag‑and‑drop, parses their layout with proprietary format‑parsing algorithms, and forwards extracted text to selectable large language models such as Gemini‑2.0‑Flash, ChatGPT or Claude. OCR modules handle scanned PDFs, while formula‑recognition and image‑translation features preserve tables and graphics. After translation, the system reconstructs the original structure, delivering a file in the target language with high format fidelity. All processing occurs without user registration, and files are deleted within 24 hours to ensure privacy.
