Translate PDFs & Keep the Original Layout

PdfTranslator deeply analyzes the underlying PDF grid structure. Translated text is perfectly embedded into its original position — images, charts, tables, and multi-column layouts remain fully intact without shifting. Whether it's an academic paper with complex formulas, a business contract with precise formatting, or a patent document with detailed diagrams, every element stays exactly where it belongs. The result reads like a native document, not a translation.

PdfTranslator gives you the best of both worlds. The Apple on-device translation engine runs entirely on your iPhone — no internet needed, complete privacy for sensitive documents like medical records or unpublished research. For complex content that needs deeper understanding, switch to the cloud Large Language Model (LLM) engine. The app intelligently selects the optimal engine for each document, balancing privacy, accuracy, and speed.

Say goodbye to rigid word-for-word translation. PdfTranslator leverages cutting-edge on-device Large Language Models for deep contextual understanding and semantic reorganization. Technical terminology is translated with precision. Sentence flow is natural and fluent — as if written by a native speaker. Plus, Smart Layout Optimization dynamically adjusts text positioning and font sizing to preserve readability while respecting the original document structure.

Researchers and students rely on PdfTranslator to quickly conquer foreign-language academic papers and track global research trends. Legal and business professionals use it to review multilingual contracts, industry whitepapers, and patent specifications offline with complete peace of mind. Avid readers enjoy imported original PDF eBooks and lengthy technical manuals without language barriers. Wherever your documents come from, PdfTranslator makes them readable.
