uploading jpegs and movie files to iCloud
I have a backup of photos and videos around 50gigs so I upgraded my iCloud to 200gigs then uploaded the whole lot from my iMac to my iCloud drive... now they are only sized 5gigs and I have noticed all the jpegs and videos have been compressed.... the jpegs used to be between 4-5mb now they are 1/10th of the size 50k... I cannot find any information on this happening to anyone else..
thanks for your help
iMac (27-inch, Late 2012), OS X Yosemite (10.10.2)
