Format error

I have a PDF format file which I use regularly on (daily basis). I don’t remember how I saved it last time but, when I open it now it gives me an error “Format error: not a PDF”.

Can you help? Any idea how to open or fix PDF file?

I am using Adobe Acrobat Reader DC
Windows 8.1

Thank you

Does the PDF file creation process generate open-able files as of now?

It’s quite possible that the file got corrupt during saving.

What is the file extension? Does it say “.pdf” or something else?

Following are the common reasons behind getting this error:

  • Due to the network issue.
  • Issue with your Browser
  • The file got corrupted
  • Improper download
    However, you can easily fix this error by making use of any repair tool.
