Hi Kenny Shutterbug,
If you share a file from Lightroom desktop version it would be in Jpeg format and the quality can be managed from 1 to 100 or you can even limit the file size as well.
And if you share via Lightroom Mobile it will share the 1:1 smart preview and you can control the quality of the images while uploading to Facebook via Lightroom Mobile.
Somehow, I doubt that sharing to Facebook will allow you to see any quality differences between desktop and mobile. Facebook limits the size in pixels of your photo (last I knew the limit was 2048x2048 pixels). So your photos shared from the desktop will be downsized by Facebook anyway.
oh I totally hear you on this, but when an image is heavily edited and not processed from the RAW vs the preview, you can tell the difference. I just don't know which happens when processing and sharing from Lightroom Mobile. It totally depends on whether or not Lightroom CC syncs the originals or only the smart previews to the cloud.
Also, I don't mean so much the output format, yeah, it will ultimately be in jpeg on Facebook, but it does matter what you process the edits from: original RAW vs Smart Preview. They are most certainly not the equivalent, and if Mobile only has assess to the preview version, there is no way that the quality from Mobile sharing will be the same as from Desktop sharing.

Good to know

Have you actually done a comparison where you can see the difference between the same photo, processed the same way, from the RAW vs the Smart Previews, as seen on Facebook?
Nope, but it sounds like I definitely should. I really just wanted someone
internal to just chime in and say "yes it processes from the original RAW"
or "no, it does not, it processes from the smart preview". No one thinks
the Smart Preview is the equivalent of the RAW.
Well, just to be 100% clear, here is what I think will be equivalent
Original RAW processed in Lightroom and exported and uploaded to Facebook and shrunk down to max of 2048 pixels on one side by the Facebook compression algorithm IS ROUGHLY EQUIVALENT IN QUALITY TO Smart preview processed in Lightroom and then uploaded to Facebook.
But I don't really know, I haven't tried. You should, if you are using Lightroom and Facebook as you describe.
I can confirm that when I share from lightroom mobile the quality sucks compared to when I share from desktop. I mean, Im looking at it from a photographers eye, so Im sure the difference isnt that bad, but to me it seems like a lot. Enough that I get up and go downstairs to share photos from my desktop once Im ready
I was just researching to see if there was anything I could do about it, and came upon this old thread
