It is not possible to upload a PDF file into a tag. However, there are 3 workarounds that still allow you to display PDFs inside your tags:
- If your PDF file is hosted somewhere, you can embed it into a tag. Copy the URL to the PDF, go to your ThingLink project and add a 'Add content from website tag', then simply paste the URL. See tag #1 in the example below.
- You can host your file on Google Drive. See tag #2 in the example below for more instructions.
- You can also used a text & media tag and add a link button that will lead to the file instead of embedding it. See tag #3.
