Hi, I looked into couple API / SDK products regarding ability to extract PDF text and resave the PDF with updated text and not sure which one to use. There's PDF Extract API which extracts info into JSON but not sure how to resave PDF using changed text:
PDF is a format utterly unsuited to what you want to do. I suggest you completely re-evaluate your requirements to find something which does not involve PDF text editing. If you are happy with the limited and frustrating editor in Acrobat, you may just need to roll out Acrobat on Mac or Windows for everyone. I'm not aware of anyone trying to bring this strange and ill-fitting tool to web services.
