# Why Office Files Must Be Converted to PDF

> The technical rationale for converting Word, PowerPoint, and Hangul files to PDF for 100% loss-free grounding.

## The Vector Loss-Free Grounding Principle

> \[!IMPORTANT]
> **Mandatory PDF Pre-Processing Policy**:
> Word (`.docx`, `.doc`), PowerPoint (`.pptx`, `.ppt`), and Hangul (`.hwp`) files must be converted (baked) to **PDF (`.pdf`)** prior to uploading to AXON.

### Why Are Raw Office Files Restricted?

1. **Parser Layout Skew**: Proprietary office XML formats frequently experience dropped tables, misplaced footnotes, and font substitution during server-side text extraction.
2. **Hallucination Vectors**: Missing table cells or misplaced footnotes in a financial or legal report cause AI models to hallucinate figures.
3. **Exact Visual OCR Grounding**: Exporting to PDF preserves the **fixed vector layout, exact coordinates, and typography**. AXON's multimodal vision engine indexes the exact visual page, guaranteeing **100% loss-free grounding and citation accuracy**.

### How to Prepare Files for Upload

* **Microsoft Word / PowerPoint**: Use **File > Save As / Export > PDF**.
* **Hancom Office (HWP)**: Use **File > Save As PDF**.
* **Google Docs / Slides**: Use **File > Download > PDF Document (.pdf)**.
