docx-to-pdf-native 0.1.4

A zero-dependency DOCX to PDF converter using only the Python Standard Library.

docx_to_pdf_native (High-Fidelity Converter)

A powerful, zero-dependency Python package to convert .docx documents (invoices, reports, resumes) to high-quality .pdf files using only the Python Standard Library.

Key Features

• Zero Third-Party Dependencies: No pip install requirements other than this package. Built using only built-in modules (zipfile, xml, zlib).
• High-Fidelity Rendering:
  • Bold, Italic, and Highlights: Preserves inline styling from Word documents.
  • Precision Word Wrapping: Intelligent layout engine using font metrics for accurate line breaks.
  • Image Extraction: Automatically embeds images (JPEG/PNG) from the DOCX at their original dimensions.
  • Tables: Renders borders and layouts structured data, ideal for invoices.
  • Bullet Points: Supports numbered and bulleted lists with proper indentation.
• Advanced Engine:
  • Unicode Support: Safely handles non-ASCII characters (like smart quotes, em-dashes, and currency symbols) via CP1252 encoding.
  • Multi-Page Support: Automatic pagination and page-break management.
  • Native PDF Generation: Independently constructs the binary PDF structure (Xref tables, font dictionaries, and trailers).

Installation

Since this is a zero-dependency project, you can simply include the folder in your project or install it via pip:

pip install .
