    Why File-Based Translation Defines LLM Pipeline Quality

    Most teams building multilingual LLM applications discover the same bottleneck: raw text extraction destroys the structure that gives documents their meaning. Tables become unreadable, numbering breaks, and scanned files return nothing at all. By the time cleanup is done, timelines and budgets are already compromised.

    Evaluating a document processing API means looking beyond language coverage. Format fidelity, OCR capability for scanned files, security certifications, and batch throughput are the factors that determine whether your pipeline actually scales.

    Bluente's Translation API is purpose-built for file-based translation across 22 formats, including PDF, DOCX, PPTX, XLSX, HTML, XML, DITA, EPUB, and image formats with advanced OCR. It preserves tables, charts, footnotes, and styling so translated files are immediately usable downstream in your LLM workflows, without reformatting or manual correction.

    SOC 2 compliant, ISO 27001:2022 certified, and GDPR compliant, Bluente meets the security requirements of regulated industries from legaltech and financial services to healthcare and insurtech.

    Frequently Asked Questions

    Get answers to common questions about our Translation API. Learn about supported languages, performance, integration options, and how to get started with our enterprise-ready solution.

    Bluente's Translation API supports 22 file formats: DOC, DOCX, PDF, PPT, PPTX, XLSX, XLS, PNG, JPG, JPEG, INDD, EML, AI, EPUB, SRT, HTML, HTM, XLF, XLIFF, XML, and DITA. This includes scanned image files processed through advanced OCR, making it suitable for the full range of documents encountered in enterprise and LLM application pipelines.

    Bluente uses advanced OCR to convert non-selectable text in scanned PDFs and image files (PNG, JPG, JPEG) into editable, searchable, and translatable content. Critically, the document structure is preserved throughout, so tables, layout, and formatting remain intact after OCR processing. This is essential for LLM applications that depend on structured data from legacy or paper-origin documents.

    Yes. Bluente's layout-aware engine preserves tables, charts, images, footnotes, headers and footers, legal numbering, and styling across all 22 supported formats. Unlike generic text-based translation APIs that strip structure from documents, Bluente processes files in their native format and returns translation-ready outputs that require no manual reformatting.

    Bluente provides a RESTful API with end-to-end encryption. Developers can upload files directly, use batch upload for multi-document processing, and track job status in real time. Webhook notifications alert your system when translations are complete, enabling fully automated, asynchronous document processing workflows without manual intervention.

    Bluente supports translation across 100+ languages, covering the breadth of multilingual use cases in enterprise, legal, financial, healthcare, and edtech applications. The API offers customizable translation profiles and a choice of ML, LLM, or LLM Pro translation engines to match the accuracy and cost requirements of your specific workflow.

    Yes. Bluente is SOC 2 compliant, ISO 27001:2022 certified, and GDPR compliant. All file processing uses encryption, and files are automatically deleted after processing. These controls meet the security and compliance requirements of regulated industries including legaltech, financial services, healthcare, and insurtech, making it suitable for confidential or sensitive document workflows.

    Bluente's Translation API is backed by a 99.9% uptime guarantee supported by a global CDN. This ensures that time-sensitive document processing pipelines, such as those used in M&A due diligence, eDiscovery, or real-time LLM applications, remain operational and reliable at scale.

    You can contact Bluente's sales team to discuss your use case and integration requirements.
