Thank you. Two excellent suggestions.
I posted on the Adobe forum and discovered that I have access to all my Acrobat tools on: https://documentcloud.adobe.com/link/home/
I haven’t tried it yet, but it appears to have all the same function I was using on my desktop version of Adobe Acrobat Pro DC. I am sure it will be somewhat slower, but probably not enough to worry about.
Thanks to everyone for the help!
