I'm proofreading a document with Adobe Acrobat (free version) and want to save comments as I go along. But when I hit the 'save' button, I can only get the 'save as' function. This means that I have to save another version of the document each time I want to save my work, which is very unhelpful. I don't want to leave saving the comments till the end in case something happens and all of my comments are lost. How do I resolve this?
As the Acrobat Reader DC is a free version, you can only use the "Save as" option.
If you are adding comments, try saving the PDF using the "Save as" option for the first time. If you wish to save the changes to the original file, browse the same location and then select replace the existing file.
Then continue adding comments to the PDF and directly save the changes. You will not receive the "Save as" window a second time in the same session. it will directly save the comments in the PDF.
