Why Can’t I Save Changes to My PDF? 

There are countless reasons as to why you may not be able to save changes made to a PDF. Common reasons may include: 

  • Your PDF editor or software is outdated. 
  • The settings are misconfigured in your PDF software, or they’ve been changed.
  • The PDF is in read-only mode or restrictions have been placed on the PDF.
  • A problem with your Adobe account.
  • Other reasons. 

Save vs Save As

While similar, Save and Save As actually do different things. 

Save 

Save means that the original file is updated and overwritten with all the changes that have been made to it. 

Save As

Save As means that a new file is created, that includes all the changes made to the original. But the original file is left as is, so you’re left with the original file and a new file with the changes. 

If you need to keep the original or “master” copy of the file, use Save As. If having an original copy doesn’t matter, you can use Save to overwrite the original file.
