1. Insert a link: In the Squarespace editor, navigate to any page and add a button or hyperlink

2. Upload the PDF: Switch the link type to File in the Link Editor and upload your PDF file there

3. Select the file: After the upload finished, you now can use checkbox next to the file to select it. By default Squarespace will generate a URL starting with /s/ (e.g., /s/sample-file.pdf). You can use this URL for embedding or sharing.

4. Since Lightbox Studio can convert the links to PDF lightbox directly, you might not need to copy the PDF URL
