Help & Answers

Frequently Asked Questions

Are my uploaded documents stored on your servers or used for AI training?
No. Uploaded documents are processed in volatile memory solely to generate your translated PDF. Documents are never permanently stored, cached, shared with third parties, or used for model training.
How does the automatic source language detection work?
When you upload a document, text samples are analyzed locally and linguistic patterns are checked using Gemini AI to automatically determine the language with high confidence. You never have to guess or manually select the source language.
Does the translator preserve original page formatting and layout?
Yes. The translation engine matches original page geometry, orientation (portrait/landscape), headings, paragraphs, and list structures, generating a download-ready PDF document matching the original layout.
Can I translate into right-to-left (RTL) languages like Urdu or Arabic?
Yes. The rendering engine includes native BiDi layout support with specialized typography stacks for Arabic, Urdu, Persian, and Hebrew.
Can I translate scanned PDF documents?
The translator requires digital selectable text. If your PDF is a scanned photocopy or photograph, you must perform optical character recognition (OCR) first before translating.
