From a couple of days my Google Chrome pdf viewer doesn't work. Whenever I try to open a pdf, nonsensical characters show up (see the image below).

Google Chrome pdf viewer gives a nonsensical output

Apart from the vertical watermark, all the characters are messed up. If I save the file on my pc and then I open it with another pdf-viewer everything works perfectly, hence the problem is strictly related to Chrome. What's strage is that the Ctrl-f function works well even for the messed-up pdf: if i look for "Hello", a string of nonsensical characters is enlightened, exactly where the actual word "Hello" is present in the correct pdf.

Any idea on how to solve this big problem?


By default, Chrome opens PDF files in the Chrome browser window.
To disable this and have PDF files open in your PDF reader program (Adobe Reader or other), follow the steps below.

Open Google Chrome
In the Chrome address bar, type about:plugins or chrome://plugins and press Enter.  

Disable the Chrome PDF Viewer plug-in by clicking the Disable link for that plug-in.  

To enable the ability for Chrome to open and display PDF files in the Chrome browser window, follow the following steps:

  • Click chrome settings in your Chrome Browser (the up right corner of the Address Bar) and then scroll down, click on Show advanced settings and then under the 'Privacy' section click on Content settings.
    In the box that pops up scroll down to Plugins. (OR Chrome Menu Button icon --> Settings --> Click Show advanced settings --> In the "Privacy section", click the Content settings button)
  • Look for the Adobe PDF Reader and Enable it (Before this step Install Adobe Reader or Adobe Acrobat if it is not already installed)
