GroupDocs Viewer Java is a server‑side component that renders over 100 document types—including CMX—into web‑friendly formats. It abstracts file parsing, rendering, and resource handling, letting you focus on business logic instead of low‑level file processing.

## Why use GroupDocs Viewer Java for CMX conversion?
- **Zero‑dependency rendering** – no need for native CMX tools.
- **High fidelity** – preserves layout, fonts, and images.
- **Scalable** – suitable for both single‑file requests and large‑scale batch jobs.
GroupDocs Viewer Java supports **50+ output formats** and can process **multi‑hundred‑page documents** without loading the entire file into memory. It delivers high‑fidelity rendering, zero external dependencies, and scales from single‑file requests to high‑throughput batch jobs.

## Prerequisites
- **Java Development Kit (JDK)** 8 or newer.

The `Viewer` class is the core component that loads a document and provides rendering methods.
`HtmlViewOptions` configures the HTML output, such as embedding resources and setting page ranges.

Load the CMX file with `new Viewer("sample.cmx")` and call `viewer.view(htmlOptions)` – that single call renders the whole document to HTML with embedded resources, preserving layout, fonts, and images. This approach works for any CMX file and requires no additional libraries.
