# PDF Viewer

The integrated **PDF Viewer** allows viewing PDF attachments directly within Business Central without leaving the application.

### Features

- **FactBox**: The PDF Viewer is displayed as a FactBox on the search result page. When selecting an attachment, the PDF is rendered directly in the FactBox.
- **Full screen view**: The full-screen page allows viewing a PDF in a larger format.
- **Alternative PDF Viewer URL**: For on-premises environments with restricted internet access, an alternative URL for the PDF Viewer can be configured in the Freeze Setup.

### Supported File Formats

The PDF Viewer displays PDF files directly. For other file formats, a placeholder PDF can be uploaded in the Freeze Setup, which is displayed instead of the file that cannot be rendered.
