PDF (embedded viewer)
Displays the PDF directly within the page using an inline frame.
Image
Renders the file as an image. Works best with actual image formats (PNG, JPG, etc.) — a PDF may not display this way in all browsers.
Video
Attempts to play the file as a video. This won't work with a PDF — included here for reference with video files (MP4, WebM, etc.).
Download Link
Provides a clickable link that downloads the file to the user's device.
Download File
Object Embed
Embeds the file using the browser's built-in handler. For PDFs, this typically renders a viewer similar to an iframe.
