A Python runtime compiled to WebAssembly that lets Python code run inside a web browser.
Pyodide is a project that compiles the CPython interpreter to WebAssembly, allowing Python packages to run inside a web browser. This converter uses Pyodide to run pdfminer.six, a Python library for PDF text extraction, entirely in the browser. Because Pyodide runs locally, the PDF parsing happens on your device without any server involvement. Pyodide is approximately 10-15MB and is cached by your browser after the first load.
Pyodide includes the CPython 3.x interpreter compiled to WebAssembly via Emscripten. It provides a virtual filesystem in browser memory, allowing Python packages to read files as if they were on disk. The converter loads the bank statement PDF into this virtual filesystem, runs pdfminer.six to extract text and layout information, and returns the results to JavaScript via Pyodide's JS-Python bridge. Pyodide supports many popular Python packages (NumPy, Pandas, etc.) but this converter only uses pdfminer.six to minimize download size.
