    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.

Hi Tim

I just double checked with one of our engineers and we don't compress photos at all. There might be something else changing the resolution during the upload time. If you want, please write us on www.dropbox.com/support with detailed description of your original file and how you see it on Dropbox, including the methods you're using to upload them, so our team can investigate it further. 

Please do not disclose any personal information on the forum.

Thanks!
