## Why Privacy Matters

When working with AI and LLMs, you often need to convert documents containing sensitive information - business reports, legal documents, personal notes, medical records, or confidential research. Most online converters upload your files to their servers, creating privacy and security risks.

**Doc to Markdown is different:**

- **Zero data transmission** - Your documents never leave your device
- **No server, no cloud** - Everything runs locally in your browser
- **Works completely offline** - No internet connection required after loading
- **No accounts or tracking** - No sign-ups, no analytics, no cookies
- **Open source** - Audit the code yourself to verify privacy claims

This makes it ideal for:
- Converting confidential business documents for AI analysis
- Preparing sensitive legal or medical documents for local LLMs
- Processing proprietary research papers offline
- Anyone who values data privacy when using AI tools

## Features

- **100% Private & Offline** - All processing happens locally in your browser, no data ever uploaded
- **Word & PDF Support** - Convert both `.docx` Word documents and PDF files
- **No Server Required** - Works as a standalone HTML file you can double-click
- **Drag & Drop Interface** - Simply drag your document or click to browse
- **Copy to Clipboard** - Instantly copy the converted markdown with one click
- **Markdown Preview** - Expandable preview area to review your converted content
- **Three Image Handling Modes**:
  - **Separate Images** (Recommended) - Clean markdown with images in a folder
  - **Base64 Embedded** - Single file with embedded images
  - **Text Only** - Lightweight output without images
- **ZIP Bundle Output** - Download everything in a ready-to-use package
- **Dark Glassmorphic UI** - Modern, beautiful interface
- **Optimized for Local LLMs** - Clean markdown output perfect for Ollama, LM Studio, GPT4All, and other local AI tools
