An experimental control that shows the content of a PDF file.

Description

Show text, graphics, and other content in a PDF file by adding this type of control and setting its Document property to the URL, enclosed in double quotation marks, of the file that you want to show.

Limitations

  1. The security architecture of Power Apps requires the PDF Viewer to support only HTTPS links, not HTTP.

  2. The Document property must link directly to the PDF file. Server redirects or HTML views of the document aren't supported.

  3. The server that hosts the document must not require authentication.

  4. You may not be able to view a PDF document in your app if the document resides on a server that has restrictive cross-origin resource sharing (CORS) settings. To resolve this issue, the server that hosts PDF documents must permit cross-origin requests from powerapps.com.

App users can work around these limitations by opening PDF documents in an external browser, as prompted if the control can't open a document. This option is also available in the control menu for all external documents.
