Can somebody help to know if there is a way to delete all the comments from a PDF in a single go?
 
I have some 1000+ PDFs, those have too many comments, i want to delete it in 1 go for each file.
 
May be i can try building a bot for that after then.
 
Please help
 
Thanks in advance

This code will remove all the comments from a file:

 

this.syncAnnotScan();
var annots = this.getAnnots();
if (annots!=null) {
	for (var i=annots.length-1; i>=0; i--) {
		annots[i].destroy();
	}
}

 

If you have Acrobat Pro you can use it in an Action and process multiple files in a single process.

If you don't have Acrobat Pro, you can use a cheap 3rd party tool called BatchPurifier to remove comments from multiple PDF files in batch.

    I went to 1. More Tools - and found the "Action Wizard" and opened it up for the doc I am working on.  2. At the top of the page I found "New Action" and chose that.  Once the box opened on the right side I chose the circle with a cross (new action) and did a cut and paste of the code above there.  NOTHING HAPPENED. 

    So I tried a second route. 1. I went to the top of the page and chose "New Custom Command" 2. once the box popped up I scrolled down and chose "Execute JavaScript"  3.  When the box popped up I did a cut and past of the code in there.  NOTHING HAPPENED.  So I am not sure where you are posting this script but I have spent far too long trying to fix this document that I needed to submit yesterday!  So frustrating.

    Did you add a Save command?

    That's possible using JavaScript and can be automated with Acrobat. I know that code that does this has been posted in these and other forums, but post again if you can't find anything with a search.
