Privacy & Security

Your privacy is guaranteed. All PDF splitting happens directly in your browser using JavaScript and the pdf-lib library. Your PDF file is never uploaded to any server, stored, or transmitted. The splitting process is 100% client-side, ensuring complete privacy and security. Once you close or refresh the page, all data is permanently deleted from memory.

Technical Details

Our PDF splitter uses pdf-lib for PDF manipulation and PDF.js for page rendering. The tool loads your PDF, extracts specified page range, creates a new PDF document, and saves it locally. Page previews are rendered using Canvas API for accurate visualization. All operations occur in your browser's memory with no server interaction.
