Hello,
You do not need any plugins. All options have been already provided.
1. Upload PDF to the media library.
2. Add the Tabs element from the WP bakery chart, insert a row inside divide it into columns.
3. insert a single image into one column, upload an image (you can upload one and the same) and then find the option to assign a link to your PDF from the Media library.
4. You can combine a single image and a Product Grid and your tabs would have both products and PDF images to open PDF.
Best Regards
