Many factors can prevent a PDF from opening in your browser or on your computer using Acrobat Reader DC or Acrobat DC. Try the suggestions below to troubleshoot the problems.

Note that you cannot repair a damaged PDF itself. However, if you have the source file, you can re-create the PDF using an Adobe product, such as Acrobat or Photoshop Elements.

Can't open PDF in your browser

Download the PDF and open it in Acrobat Reader DC or Acrobat DC

  1. Right-click (Windows) or control-click (Mac OS) the link to the PDF file.

  2. Choose the appropriate save or download option for your browser:

Symptom or error TechNote or solution
Can't open a password-protected PDF Opening secured PDFs
Opening suspicious PDFs: Reader and Acrobat block PDFs that do not conform to certain industry-specific PDF standards, or may contain potentially harmful content. Be cautious. These PDFs can pose a security risk to your system. Double-check with the source of the doc, such as the person who sent it to you or the website you downloaded it from, to make sure the document is safe to open.
Can't open a PDF created with older, or non-Adobe products

If you trust the creator of the PDF and its origin, consider reverting to an earlier version of Reader or Acrobat to open the PDF. Reverting to an older version requires first uninstalling the version of Acrobat or Reader currently on your drive.

You get an error message when trying to open a PDF created in InDesign or Illustrator.
