For InDesign to PDF file conversion, you can open Adobe InDesign files in the Adobe Acrobat .pdf file format, using helpful features in Markzware’s IDMarkz app. You will be able to add annotations and see the PDF comments in InDesign! Read more about it and see the video, below:
InDesign to PDF
Markzware’s IDMarkz app can open your InDesign file in Acrobat. You can, then, annotate in Acrobat and save the PDF. This will allow you to see those comments in InDesign’s PDF Comments Panel. This is useful, because it frees you from being restricted to using InDesign files created in only CC 2019 or later.
Markzware develops preview, preflight, and file conversion software for printers, publishers, graphic designers, creative professionals, and the like. Markzware’s IDMarkz is a standalone, multi-featured application that previews and converts Adobe InDesign files, for use in several file formats on the macOS platform.
IDMarkz can help you to convert InDesign to PDF. This video demonstration walks you through the steps:

You can create a PDF from an Adobe InDesign file, using IDMarkz. You will be able to mark up the PDF, by adding comments, notes and annotations.
You can, then, send the PDF to the client for review. The client need not run nor “rent” the Adobe InDesign program, nor pay for a Creative Cloud subscription, to be able to inspect the document, suggest changes, and express level of approval.

[with IDMarkz]…
“it seemed quite a more or less seamless integration, immediately when you export. If you have the Adobe Creative Cloud software on your computer, it opens up, immediately. So, you can check if it’s been converted in a way you’re happy with, so… And the same, like about… You immediately get it opened. If you export a PDF, you get it immediately opened in Acrobat DC. I see many, many types of users that would appreciate this kind of commercial software.”
