Embedded PDFs can be displayed in four PDF viewer modes:
- Lightbox: Displays PDF files in a modal.
- Sized Container: Displays PDF files in a presentation-style container with landscape orientation. Each page of the embedded PDF file appears as a slide. This is the default mode that applies to all embedded PDFs.
- In-Line: Displays PDF files inline within the content of the page or post itself. When using this mode, all pages within the embedded PDF file are displayed at once.
- Full Window: The viewing area fits the size of the parent element and can be customized to cover the entire browser window. Unlike the Sized Container mode, which also fits the size of the parent element, the Full Window mode allows your visitors to use annotation tools, navigate pages using PDF thumbnails, and access other features of the Full Window embed mode of the Adobe PDF Embed API.
