The Technology Behind BigTranslator
AI-Powered Translation
We use Claude AI, one of the most advanced language models, for accurate translations that understand context, idioms, and technical terminology.
Page-by-Page Processing
Unlike tools that choke on large files, we process your document page by page. This lets us handle 500+ page documents that competitors reject.
Format Preservation
Our system extracts text while mapping its position, translates it, then reconstructs your document with the original layout, fonts, images, and tables.
Secure Processing
Your document is encrypted during upload, processed in isolated containers, and permanently deleted after you download. We never store or train on your content.
Your Document, Just Translated
Everything you need stays intact.
