When we launched file uploads and attachments last month, we heard your feedback that you’d also like to be able to see PDF files in-line with other page content. As of today, you can do exactly that!
After you’ve attached a PDF to a page, right click it to open your display options. Select "Embed,” and resize as desired. Be advised that the file has to finish uploading for the “Embed” option to be available.
Pro tip: This also works for mp4 files!
You can still click on the file to view it in the light box, or right click to download. Cheers!
