Are images missing when you open your PDF, or are you seeing black lines where the images should be, like this? Missing or blurry images, or black lines in a PDF usually happen when the file is opened in an outdated or incompatible PDF viewer. Here is an example of black lines you may see in a PDF if it is opened outside of Adobe Reader:
In most cases, switching to the latest version of Adobe Acrobat Reader resolves the issue. For example, Mac computers use an application called Preview by default, which may not work 100% with all PDF files.
- Make sure you have the latest version of Adobe Acrobat Reader installed.
- Open Adobe Acrobat Reader.
- Go to "File" at the top of your screen.
- Choose "Open" and select the PDF from your computer.
After installing Adobe Acrobat Reader, you may be prompted to make it the default program for opening PDF files. It's a good idea to say yes, so you won't have to repeat the "Open With" process for every PDF that you want to view or print. There are many applications for PC and Mac that will open a PDF, but Adobe remains the most compatible.
