PDF viewing has been with us in Gmail for a while now, and since many times I just need a quick info or two from a pdf, it became quite comfortable being able to open it right in my browser from Gmail. The Official Gmail Blog just announced that they have added tiff and ppt support as well!

I don’t really use tiff a lot, but scanned files are often saved in tiff, which can be a multi-page document that some software has problems with. I didn’t try this myself, but apparently Gmail will have no problem with these documents, they will open in the same way as they were intended to, multi-page images.

The ability to view presentations on the fly, in the same viewer, is also great, no need to download and open with office, or go to a separate viewer, it will open right there in your browser. Again, on my end I usually do not need to actually have these saved, I use ppt-s for data flow information and so on, no need to have them constantly on my hard drive.
