Frequently Asked Questions
How does Chat with PDF work on PDFtiny?
PDFtiny extracts the text from your PDF locally using PDF.js and sends your questions alongside relevant context to Google Gemini AI via your API key. Your entire document is never stored on any server.
Is my confidential PDF shared with anyone?
No. Text parsing runs entirely in your browser. When querying the AI, text snippets are transmitted via secure HTTPS directly to the Gemini API endpoint and are never recorded in any database.
What types of documents can I analyze?
You can upload research papers, financial reports, legal contracts, textbooks, student lecture notes, and user manuals up to 100+ pages.
