How It Works

This tool uses the anydoc-wasm engine to parse documents locally in your browser via WebAssembly. The engine embeds a lightweight document parser with no external dependencies like PDF.js or LibreOffice. It directly reads byte streams from PDF/Word/Excel/PPT and other formats, extracts text content, table structures, and heading hierarchies, and outputs them in GitHub Flavored Markdown format. The entire 6.7MB WASM binary runs inside the browser sandbox — zero server dependencies.

Privacy & Security

All documents are processed exclusively within your local browser WASM sandbox. Nothing is uploaded to the cloud. Memory is automatically freed after conversion — no risk of data leakage.
