You drag a file into the page, choose source and target languages, optionally select which AI model should do the translation, and download the result. Headings, multi-column layouts, tables, embedded images and mathematical formulas are reconstructed in the target language rather than dumped out as plain text. The format list is unusually broad for a free tool: PDF, DOCX, PPTX, XLSX, EPUB and TXT documents, plus JPG, JPEG and PNG images. Scanned PDFs and pictures inside documents are handled with OCR, which means photographed contracts, scanned manuals and image-heavy brochures are still translatable. The service advertises support for more than 60 languages and lets you choose between several model backends, so you can trade speed against nuance for a given job. Beyond document translation, BelinDoc bundles adjacent tools: a manga translator that keeps the original artwork while replacing dialogue, a video translator with subtitle and dubbing output, and a plain text translator. The core document workflow requires no account, and the service states that uploaded and translated files are deleted within 24 hours. Paid Premium options exist for higher throughput, priority processing and extra quota. **Pricing & Plans:** BelinDoc's document translation is free with no registration, and the site also offers Premium options for faster processing, priority queues and additional quota, plus TransPDF API access for developers. Contact BelinDoc for enterprise or API pricing. - **Layout-preserving translation:** The translated output keeps headings, columns, tables, figures and formulas in their original positions, so you rarely need to reformat after conversion. - **Wide format coverage:** PDF, DOCX, PPTX, XLSX, EPUB, TXT plus JPG, JPEG and PNG images are all accepted, with OCR for scanned or image-only documents. - **Multiple AI model choices:** Pick between ChatGPT, Claude, Gemini and DeepSeek as the translation engine depending on the tone and accuracy you need. - **No login and privacy-focused:** Upload and translate without registering an account, with a zero-retention policy and file deletion after translation. - **Specialised translators:** Separate tools for manga pages, subtitled or dubbed video, and plain text, so you are not forced through the document pipeline for everything. **Strengths:** Genuinely free core document translation with no account required; Strong format fidelity — tables, columns, formulas and images survive translation; OCR support makes scanned PDFs and image documents usable; Choice of multiple leading AI models for the translation engine [Profile (Markdown)](https://openaitools.app/tool/belindoc.md) ## LangPDF LangPDF is an online tool focused on producing professional PDF documents from short text prompts. You start by describing the document you want — an invoice, resume, contract, report, proposal, quote or letter — and the platform assembles a structured, downloadable PDF. A library of templates is included so you can begin from a professional layout and adjust it rather than designing everything from scratch. Typical workflows include generating business documents without manual formatting, customizing ready-made templates, and standardizing recurring paperwork such as receipts, product requirement documents, reports and standard operating procedures. Everything is done in the browser: you preview the result online and download it when it looks right. The pricing is tiered by output volume. A free plan covers occasional needs with a small monthly quota, while Pro and Team tiers raise the number of documents you can generate each month for regular professional or high-volume business use. Exact quotas and prices are listed on the official pricing page. **Pricing & Plans:** Freemium with tiered plans by monthly output volume: a Free plan for occasional use (about 5 documents per month), a Pro plan for regular professional output (about 300 per month) and a Team plan for higher-volume business use (about 1,500 per month).
