# View and edit workspace files in Palette Desktop

> Use Palette Desktop's viewer to read and edit Markdown, preview HTML, and inspect files beside the chat that created them without leaving the workspace.

The viewer is where you see and work with your files inside Palette Desktop, without switching to another app. Open a file from the file panel and it shows up in the viewer.

## What you can do

* **Read and edit markdown.** Markdown files open in a clean editor you can type into directly, and they stay plain markdown on disk. See [Editing markdown in the viewer](/docs/desktop/editing-markdown).
* **Preview HTML.** HTML files render right in the viewer, and you can open them in a browser or share them. See [HTML files](/docs/desktop/html-files).
* **View your other files.** It also previews files like PDFs, images, and code, and shows the red and green diff when you review a session's changes.

## Why it matters

Your work stays in one place. You do not need a separate markdown app to read your notes, or a browser tab to check a prototype. You edit, preview, and review right next to the chat that produced the work.
