**Definition anchor:** `Viewer` is the core class of GroupDocs.Viewer that loads a source document and renders it into the selected output format.

Now let’s dive into the concrete conversion scenarios.

## Implementation Guide

### Feature 1: Render TXT to Multi‑page HTML *(multi page html java)*
**Direct answer:** Use `HtmlViewOptions.forEmbeddedResources` and call `viewer.view(documentPath, options)` – this generates a series of HTML pages, each representing a portion of the original text, while automatically embedding CSS and images.

#### Overview
This example converts a TXT document into a **multi‑page HTML** file, preserving line breaks across separate web pages.
**Definition anchor:** `HtmlViewOptions` configures how the Viewer renders a document to HTML, including pagination, resource embedding, and CSS handling.

*Explanation:* `HtmlViewOptions.forEmbeddedResources` bundles CSS, fonts, and images directly into the HTML output, making it portable.

### Feature 2: Render TXT to Single‑page HTML *(convert txt to html java)*
**Direct answer:** Call `HtmlViewOptions.forEmbeddedResources().setRenderToSinglePage(true)` before invoking `viewer.view`; the entire TXT content will be collapsed into one HTML file, ideal for quick previews.

#### Overview
Condense the entire text file into a single HTML page—perfect for quick previews.
**Definition anchor:** `setRenderToSinglePage(true)` forces the Viewer to merge all generated pages into a single HTML document.

*Explanation:* `setRenderToSinglePage(true)` merges all pages into one HTML file.

### Feature 3: Render TXT to JPG
**Direct answer:** Create a `JpgViewOptions` instance, optionally set DPI for higher quality, and pass it to `viewer.view`; the Viewer will output a JPEG image for each page of the source TXT file.

#### Overview
Convert a TXT file into a high‑quality JPEG image, useful for sharing on platforms that only accept images.
**Definition anchor:** `JpgViewOptions` defines image‑specific rendering settings such as resolution, quality, and output folder for JPEG conversion.

### Feature 4: Render TXT to PNG
**Direct answer:** Use `PngViewOptions` with a desired DPI (e.g., 300) and invoke `viewer.view`; the result is a lossless PNG image per page, preserving the exact visual layout of the text.

#### Overview
Generate lossless PNG images from text files—ideal when you need crisp, scalable graphics.
**Definition anchor:** `PngViewOptions` provides configuration for rendering documents as PNG images, supporting lossless compression and custom resolution.
