Have you ever used Acrobat to edit a PDF and then couldn't save it? Here we'll explain how to fix that issue.
It's simple: save the file as a PostScript, then use Acrobat to convert the PostScript back to PDF; you can then save. Note this flattens images and may reduce image quality.
- File > Export To > PostScript
- Open the PostScript file in Acrobat.
- Convert to PDF — done.
