 ## Supported file types in Chat
 
 Chat empowers you to work with a wide range of file types, both for input and output. Upload documents, images, and data files to provide context to your conversations, and generate new files based on your Agent's responses or built-in Agent outputs. Whether you're analyzing spreadsheets, processing PDFs, or creating presentations, Chat seamlessly handles file operations across different model providers.
 
 Here's a comprehensive breakdown of supported file types by model provider:

+### File preview capabilities
+
+Chat can preview 70+ file types directly in the interface, so you can view a file without leaving the conversation. Supported categories include:
+
+- **PDFs**
+- **Images:** PNG, JPG, GIF, WebP, SVG
+- **Videos:** MP4, WebM, MOV
+- **Spreadsheets:** CSV, XLSX
+- **Code files:** JS, TS, Python, JSON, HTML, CSS, Markdown, and 20+ other programming languages
+
+Files without extensions (such as `Dockerfile`) are treated as plain text and can be previewed. If a file type is not supported for preview, Chat displays a "This file type can't be previewed" message.
+
+<Note>
+File preview (viewing a file in the chat UI) is separate from file processing (what the LLM can read and reason about). Preview support does not affect which files an LLM can process — that remains provider-dependent. See the file capabilities section below for details.
+</Note>

 ### File size limits by provider
 
 File size limits vary by model provider. Each provider has limits for individual files and combined attachments in a single message.
