Many factors can prevent a PDF from opening in Adobe Reader or Acrobat. Try the following suggestions as your first troubleshooting steps, or refer to the topics below for additional information.

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.

Open a PDF in your browser

Try this if you’re having trouble opening a specific PDF on a web page. This won’t work for other PDFs.

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

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

    • (Google Chrome) Save Link As
    • (Internet Explorer) Save Target As
    • (Firefox) Save Link As
    • (Safari) Download Linked File
  3. Make sure Adobe Acrobat Document is selected for the file type, and save the file.

    Note:

    If you don't see a Save As dialog box, your browser may have downloaded the file automatically, possibly in a separate downloads window.

  4. Locate the saved PDF, and double-click the file to open it. If your browser opened a downloads window, double-click the PDF in the downloads list.

Other issues you may encounter

Viewing password-protected PDFs

Issue:
The creator of a PDF can add password security to a document to prevent unauthorized users from viewing the PDF.

Solution:
To open this type of document, enter the password when prompted. If the PDF creator has not shared the password with you, you cannot open the PDF.

Handling suspicious PDFs

Issue:
Reader and Acrobat block PDFs that do not conform to certain industry-specific PDF standards, or may contain potentially harmful content.

Solution:
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, then proceed with the rest of the troubleshooting steps.

PDFs won’t display on the web

Issue:
When you try to view a PDF on a website, you see one of the following:

  • A blank page in your browser
  • A red X icon 
  • A broken-link indicator (a red square, a blue triangle, or a blue circle) 
  • The error message: "The Adobe Acrobat/Reader that is running cannot be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again."

Solution:
Try the solutions beginning at the top of this page, and if you still can’t view the PDF, view Troubleshoot viewing PDF files on the web.

Opening PDFs created with older, or non-Adobe products

Issue:
PDFs created with non-Adobe products or earlier versions of Reader or Acrobat may not open in Reader or Acrobat.

Solution:
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.

(Reader) See Reader older versions.

(Acrobat) See Acrobat 8 and 9 or Acrobat XI and X.
