Common Ways to Verify PDF Integrity
Once a PDF is corrupt, you can’t open it and make changes to it. This is pretty confusing. Like others, you may wonder: how to check if PDF is corrupt. Fortunately, you can verify PDF integrity through some methods.
For instance, try opening the PDF via a PDF viewer or editor to see if it opens normally. If it opens properly, it means that the PDF file isn’t corrupt. If it doesn’t open or shows an error message, it might be corrupted.
It is reasonable to doubt that PDF is corrupt when issues like Edge not opening PDF, PDF not opening in Chrome, or PDF not opening in Outlook happen. It’s worth noting that you should try a different viewer or browser to open the PDF if it doesn’t open in one viewer or editor.
