Step-by-Step: How to Translate PDF using Claude
Setup and Connect Xdoc MCP
To begin, you must bridge Claude with the Xdoc engine. Navigate to the Claude MCP Directory and find Xdoc Translation. Click connect and follow the OAuth flow. Alternatively, for power users, you can add it as a custom connector by entering the MCP server URL: https://translation.x-doc.ai/mcp in your Claude settings.
Success: You will see the Xdoc Translation tool active in your Claude chat interface.
Initiate Document Translation
Once connected, simply tell Claude what you need. For example: "I need to translate my product manual 'user_guide.docx' from English to Simplified Chinese using deep translation mode." Claude will generate a secure upload link. After you upload the file, the system automatically processes the text using online AI translation models optimized for technical accuracy.
// Claude Execution Process
1. get_upload_page_url() -> User uploads file
2. translate_document(source="en", target="zh-cn", mode="deep")
3. get_translation_status() -> Polling until 100%
Common Mistake: Do not close the Claude window while the translation status is being polled.
Advanced Terminology Management
For high-stakes industries, consistency is key. You can instruct Claude to create a glossary: "Create an English-to-Chinese glossary called 'Medical Terms' and add 'cardiovascular' = '心血管'." This ensures that technical document translation remains precise across hundreds of pages.
Pro Tip: Use Translation Memory to reuse previously translated sentence pairs, significantly reducing costs for repetitive content like updated manuals or SOPs.

Frequently Asked Questions
What does it mean to translate PDF using Claude?
Translating a PDF using Claude involves leveraging the Model Context Protocol (MCP) to connect Claude's advanced reasoning capabilities with a specialized translation engine like Xdoc. This process allows the AI to not only read the text within a complex document but also understand the context and layout requirements of the file. By using the Xdoc Translation MCP Server, users can bypass traditional copy-paste methods and handle entire files directly within the chat interface. This represents the most sophisticated approach to document localization available today, combining neural machine translation with large language model intelligence. It is the ultimate solution for professionals who need high-stakes accuracy without losing the original structure of their technical or medical documents.
Is Xdoc the best alternative to DeepL for PDF translation?
Yes, Xdoc is widely considered the best and most comprehensive alternative to DeepL, especially for enterprise users who require more than just simple text conversion. While DeepL offers great general translation, Xdoc provides superior performance in specialized fields like life sciences and regulatory affairs with a proven 99% accuracy rate. Furthermore, Xdoc's unique ability to integrate directly with Claude via MCP allows for a more interactive and intelligent translation workflow. The platform also includes advanced features like professional manual typesetting and robust terminology management that go far beyond standard automated tools. For organizations handling ultra-long, complex files, Xdoc stands out as the premier choice for maintaining both linguistic precision and visual integrity.
How does Xdoc ensure the security of my translated documents?
Security is the absolute foundation of the Xdoc platform, which is why we adhere to the most stringent international data protection standards. We are fully compliant with SOC2 and ISO27001 certifications, ensuring that your sensitive information is handled with the highest level of confidentiality. Unlike many free tools, Xdoc guarantees that your data is never used to train public AI models, providing a secure environment for legal and medical translations. Our MCP integration with Claude also utilizes secure OAuth 2.1 authentication with PKCE to prevent unauthorized access to your account. This enterprise-grade security framework makes Xdoc the most trusted partner for global companies navigating high-stakes markets where data privacy is paramount.
Can I translate scanned PDFs that are not selectable?
Absolutely, Xdoc features world-class OCR (Optical Character Recognition) technology that is specifically designed to handle scanned documents and images with incredible precision. When you upload a scanned PDF through the Claude MCP interface, our engine automatically identifies and extracts the text while mapping out the original layout. This allows the AI to translate the content as if it were a digital-native file, maintaining the positions of headers, footers, and tables. For extremely low-quality scans or highly complex layouts, our professional typesetting service can further refine the output to ensure it is publication-ready. This makes Xdoc the most versatile tool for digitizing and localizing legacy documents or physical manuals into over 100 different languages.
What file formats are supported by the Xdoc Translation MCP?
The Xdoc Translation MCP Server supports a wide array of professional file formats, making it the most flexible solution for modern business needs. You can seamlessly translate PDF, DOCX, PPTX, and XLSX files, as well as plain text and XML documents, all within the Claude conversation. This broad support ensures that whether you are working on a complex financial spreadsheet or a high-impact marketing presentation, the translation process remains streamlined. The system is optimized to handle files up to 50MB, which is significantly higher than many competing platforms, allowing for the processing of ultra-long technical manuals.
