When you try to view a Word document or PDF in Google Chrome, the file is downloaded to the hard drive. That document may not have even been the one your were looking for. The result: You got a document you don’t need.
The Docs PDF PowerPoint viewer extension makes Google Docs your default online document viewer for Google Chrome. With this, you don’t need to download the document just to view the content. All you have to do is click the document (PDF, pptx or docx) link and the document opens in your Google Docs account. Next, you can download the document from Google Docs as usual.
