Belin Doc

Belin Doc lets you select the source language, target language, and model, then upload files such as PDF, EPUB, DOCX, PPTX, XLSX, TXT, and images. The settings section also offers options like translating images within PDFs, enhancing formula recognition, email notifications, and a priority queue, all aimed at minimizing post-translation reformatting.

The current public upload area displays up to 2 concurrent tasks and shows the remaining pages, OCR pages, and the number of accelerations; for this session, the displayed page count is 0 if you’re not logged in. Although the FAQ advertises free, unlimited usage and specifies a per‑submission page limit, it does not guarantee unlimited submissions without any quota, nor does it automatically grant Premium or OCR benefits to the free tier. Translations, formulas, and formatting must be reviewed item by item.

Researchers, office workers, and multilingual document users

2026-10-25 Currently, the control column supports a maximum of 2 concurrent tasks; for unlogged-in users, the remaining number of translation/OCR pages is displayed as 0. Although the FAQ states that the service is free and unlimited, it also explicitly specifies a limit on the number of pages per session. In practice, the actual submitable volume, OCR capabilities, and Premium conditions are verified based on the account; do not enter any page limits or amounts that have not been confirmed.
