PDF to Word Converter

🇨🇳 简体中文 / Simplified Chinese

A skill to extract text from scanned PDF documents and convert them into reusable Word (.docx) files using the free, local docr OCR engine.

Prerequisites

1. Initialize the OCR engine by downloading the binaries:

   bash scripts/install.sh
   

2. Install the required Python dependencies:

   pip install -r scripts/requirements.txt
   

Usage

Run the Python script passing the input PDF file and the desired output .docx file path. You can also append any additional standard docr arguments (such as engine preferences).

python scripts/pdf2word.py \x3Cinput.pdf> \x3Coutput.docx> [docr_args...]

Examples

Convert a single file with the default local engine:

python scripts/pdf2word.py sample.pdf sample_output.docx

Using Other API Engines

By default, the script uses the local RapidOCR engine. The underlying docr tool also supports other engines like the Google Gemini API for potentially higher recognition accuracy on complex layouts.

To use Gemini, first configure your API key:

mkdir -p ~/.ocr
echo "gemini_api_key=your_gemini_key" > ~/.ocr/config

Then pass the -engine gemini argument to the script:

python scripts/pdf2word.py sample.pdf sample_output.docx -engine gemini

If your document has tables, you can force Gemini to output them in Markdown format so the script can parse them into native Word tables:

python scripts/pdf2word.py sample.pdf sample_output.docx -engine gemini -prompt "Extract all text and preserve tables in Markdown format using | symbols."

How it Works

1. The script calls docr, which uses the specified OCR model (RapidOCR by default) to read text from the scanned PDF.
2. The extracted text is temporarily stored.
3. The python-docx library is used to read the temporary text and construct a formatted Word document.
4. Temporary files are cleaned up automatically.
