Hi Tom,
You should be able to do this by uploading the PDF to the files section of your Shopify admin:
- Go to https://YOURSHOPIFYSTORE.myshopify.com/admin/settings/files
- Click the Upload Files button in the top right and select the PDF to upload
- Once it uploads copy the text in the URL field, it should start with https://cdn.shopify.com/s/files…
Once you have that URL you can place it into your pages. Depending on how you’re theme’s setup you could use the following HTML:
View](https://cdn.shopify.com/s/files…">View) Returns Policy
Where "https://cdn.shopify.com/s/files…" is the URL you copied from before.
Hope this helps!
