Till now if you receive any PDF file as attachment on Gmail, you had to click on ‘view’ link that will bring up PDF file contents in HTML format minus formatting and images. Well, from here on clicking ‘view’ link will open PDF file in all its glory within web browser.
In short, you can view PDF file in original format even on computer that does not have software to read PDF files (like Acrobat reader). You will see PDF file with thumbnails on the right side for easy browsing and view. This new Gmail feature is powered by Google Docs PDF File support.
So next time you receive a PDF file as attachment on Gmail, no need to download the file and open it with Acrobat software (that takes ages to open). Just click on view link and preview PDF file quickly within web browser without worrying about additional software – neat!
