HTML object element

The <object> HTML element represents an external resource, which can be treated as an image, a nested browsing context, or a resource to be handled by a plugin.

The <object> element can display PDFs using the browser’s built-in PDF viewer. Its children provide fallback content when the resource cannot be displayed. You can use this to provide a link to the PDF, but also provide a link outside the element so it remains available if the viewer loads but fails to display the PDF.

Unlike <iframe>, <object> has no attributes that control loading. The embedding page’s Content Security Policy controls its sources through .
