Why Choose Our Patent Translation Services?
DocTranslator translates patent documents with AI and keeps their numbered claims, figures and page layout in place. Because a patent's scope depends on the exact wording of its claims, have a qualified translator or patent attorney review any translation you plan to file.
Below you will find detailed advantages of our service:
File Size Up to 1 GB
DocTranslator lets you upload and translate very large patent files without any size-related limitations. You do not need to split or compress your documents before translation. Even complex patent applications with hundreds of pages can be handled in a single process while keeping the translation workflow fast and efficient.
Formatting Preserved
Whether your patents are in PDF, DOCX, TXT, or image formats, the translated result will maintain the exact formatting and layout. Tables, diagrams, and page structures remain consistent across the translated file. This ensures your patent documents are ready for official submission or review without any additional manual adjustments.
120+ Languages
With coverage of more than 120 global languages, you can translate your patent documents for international jurisdictions without barriers. DocTranslator supports widely used languages like English, German, Russian, and Spanish, as well as more specific markets such as Japanese, Korean, and Chinese, ensuring smooth cross-border patent protection.
Translation Accuracy
Patent documents often contain complex terminology and legal phrasing. DocTranslator uses advanced AI technology to translate every section with high precision while preserving the original meaning. Our solution reduces human error and ensures that the translated patents meet legal and technical standards required by international offices.

Frequently Asked Questions
Can I translate large PDF files online with AI?
Yes, DocTranslator uses AI-powered technology to translate PDF files up to 1 GB or 5,000 pages in length on the Pro and Business plans. Basic takes files up to 100 MB and 300 pages, and Free up to 20 MB and 20 pages.
What file formats does DocTranslator support?
DocTranslator supports DOCX (Word), PDF, XLSX (Excel), PPTX (PowerPoint), IDML (InDesign), TXT, JPG, JPEG, PNG, CSV, and JSON files. You can drag and drop files or browse your device to upload them.
How much does it cost to translate documents with AI?
Signing up is free, and on the Free plan every AI translation is paid per document: $0.005 per word, or $1 per page for scans, with a $0.99 minimum. A subscription includes AI translation every 30 days: up to 1,000 pages on Basic (from $1.99 a week) and up to 5,000 on Pro ($19.99 a month) and Business ($49.99 a month). All plans include 120+ languages and full file format support.
How many languages does DocTranslator support?
DocTranslator supports over 120 languages including Spanish, French, German, Chinese (Mandarin and Cantonese), Japanese, Korean, Arabic, Portuguese, Italian, Russian, and many more.
How fast is the AI document translation?
It depends mostly on the document. A short PDF with a text layer comes back sooner than a long scan, because each scanned page has to be recognised (OCR) before it can be translated. There is no setup step before that: you upload the file, choose the two languages, click "Translate" and download the result in its original format and layout.
Does DocTranslator preserve the original document formatting?
Yes, DocTranslator maintains the original language style, formatting, fonts, and layout of your document. The AI ensures accuracy and context while preserving the natural flow of your original document across all supported formats.
Is my document secure when using DocTranslator?
Yes, all communications with DocTranslator are encrypted. Your private documents are handled with discretion, and only authorized personnel can view your files. DocTranslator has robust privacy policies in place.
Can I preview my translation before paying?
Yes. Every PDF translation includes a free preview of the first page, so you can check accuracy and formatting before you pay. For a fuller check, translate a short document first: AI translation is paid per document, from $0.99.
What's the difference between AI translation and human translation?
AI translation is instant and affordable ($0.005/word on Free, less on Pro, paid per document) and ideal for quick understanding of content. For official purposes like USCIS submissions that require certified and notarized translations, you must use human translation services.
How do I get started with DocTranslator?
Create a free DocTranslator account by signing up with your name, email, and password. Then upload your file (Word, PDF, PowerPoint, etc.), select source and target languages, click "Translate," and download your translated document.
