    I uploaded a 107.5MB TIFF file to Dropbox using a desktop browser, then downloaded the file. I then compared the file in my download folder to the source file. 

    Both were exact matches down to the byte: 107,525,5436 bytes.

    I then checked for JPG. Also an exact match 9,177,764 bytes.

    Then I checked CR2 files (Cannon's proprietary file extension) 

    Drumroll...both files were 23,921,835 bytes.

    If you are using some mobile app to upload your photos...switch to desktop if you care about such things, but blame the right party.

    Last I checked, I do not work for Dropbox, nor do I own any stock. If you call someone a liar, you better be able to back it up at least as well as dropbox backs up your files.

    So why is photo quality drastically reduced when I view a photo on my tablet, uploaded from desktop?

      I've noticed this to, but after a few seconds it's refreshing the picture to full resolution. Probably because the pic is been downloaded in the background.
