does Dropbox compressed photo files???
I'm sending full resolution photo files to clients instead of burning them on a disc, but I want to make sure they are the full resolution. I had a client that had pictures made at Walgreens, and the...
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.

Sorry but i think you're being a bit slow as I said, I have an Android phone so CAN'T test it myself, telling me I should go and test it is simply ignoring what I have said or failing to read it.
And anyway, I did have it tested as I said, and he didn't "checksum" the files he didn't need to he performed a binary compare on the data and found it identical.
The orginal files consisted of 4 camera photos, 4 existing photos, 4 added photos
The original files were compared to (1) web downloads from DB : identical
The original files were compared to (2) desktop synced from DB : identical (data stream)
The only differences detected was the addition of the DB ADS stream attached to the file when downloaded via the desktop client, for most users they would not even know this exists, and its content has no reference to the datastream.
