How does it work?

For PDF files, this tool uses PDF.js (Mozilla's official library) to render the first page directly onto an HTML5 canvas in your browser. For Office files (Word, Excel, PowerPoint), the tool extracts text content and structural information to generate a readable text-based preview. Because all processing happens locally, your sensitive documents are never transmitted to any server.
