how to add a link

Hi Gnoria Bowens,

You can't add links using 'Acrobat.com Online Service', However you can use Acrobat Standard or Pro software to Create a Link in PDF.

In Order to Create Links using Acrobat software, Please Visit this Webpage- Adobe Acrobat X Pro * Create a link - This Link Describes the procedure to create link if you are using Acrobat X pro.

The options  detailed on the above link might differ from the One shown in your version of Acrobat, so if you can let me know the Version of Acrobat you are using, I can help you more Accurately.

Hope to hear from you soon,

Regards,

Rahul Tyagi
