Remove PDF annotations via command line

Question

Is there a way to remove all PDF annotations (including highlights, comments, notes, arrows) in bulk (e.g., via command line)?

Answer 1

The following series of commands solved my problem:

pdftk in.pdf output - uncompress | sed '/^\/Annots/d' | pdftk - output out.pdf compress

Thanks @Farid Cheragi for the oneliner!
