Belin Doc is a free web translator for PDF, DOCX, PPTX, XLSX and EPUB files that preserves layout, tables and formulas. It needs no login, supports 60+ languages, offers several AI models, and also covers manga, video and text.
Belin Doc is a browser-based document translator that converts files between languages while trying to keep the original layout in place. Users drag in a PDF, DOCX, PPTX, XLSX, EPUB, TXT or image file, pick a target language, and receive a translated version with tables, figures and formulas still positioned as in the source. Scanned PDFs and images are handled through OCR, and the site says it understands more than 60 languages. The tool targets people who regularly receive documents they cannot read: academic researchers, marketing teams localizing collateral, cross-border e-commerce sellers working through product manuals, and finance staff handling spreadsheets. Because it requires no account, a first translation takes only a few clicks. The interface exposes a model selector with options from Gemini, ChatGPT, Claude and DeepSeek, plus toggles for translating images inside PDFs, enhanced formula recognition and email notification when a job finishes. A priority queue is marked as a premium feature. In practice, the homepage presents a free tier with a stated page quota that grows after registration, a cap on parallel tasks, and a per-translation page limit the operator says exists to keep the service available to everyone. Translation typically takes one to ten minutes depending on file size and server load. According to the FAQ, original and translated files are deleted within 24 hours and no personal data is required, although the feature list also describes a zero-retention policy, so buyers with strict confidentiality needs should read the terms closely. Beyond documents, Belin Doc offers a manga translator that keeps artwork, a video translator with subtitles, SRT export and AI dubbing, a text translator, and a separate premium translation page. Compared with general-purpose chatbots that flatten formatting, and with paid desktop translation suites, it occupies the free, format-faithful end of the market. The tradeoff is dependence on a free service with usage caps and no mobile apps yet, which the operator lists only as a future plan.
