How to change a PDF's title? (not file name) My question is in reference to the title shown in Acrobat Reader's tab and title bar that reads "Modern business letter."



I generated the PDF from a .docx document, and the document is generated based on a LibreOffice template (.odt) named "Modern business letter", which is where the title name comes from.

I know how to change the template name in LibreOffice, but that can cause unwanted error if I forget to change it the next time I use the same template. Im looking for other macOS options so I don’t have to struggle in LibreOffice. 

How do I change the individual PDF title, either in Acrobat Reader or in Finder?
To answer the question you asked, &quot;How do I change the individual PDF title, either in Acrobat Reader or in Finder?&quot;, you can't. Neither Acrobat Reader or Finder, by default and natively, have the capability to edit that information. It needs to be done before being exported/printed to PDF or use an app capable of editing PDF Documents.
The industry standard is Adobe Acrobat however it's an expensive app and overkill if looking to just edit that information.

If you have exiftool installed and want to do it from the command line in Terminal, use the following syntax:
exiftool -Title=&quot;New Title&quot; /path/to/filename.pdf


To clear the Title, just use: -Title=&quot;&quot;
Other meta-data can be changed in a similar fashion.
