LR Mobile: Export vs Share file sizes

Before the latest update, Share had two options: 2K image and largest available size (something like that.). Largest size gave me a file size that was around 4mb.

Now, the Largest size option is gone from Share and I have to go through Export (An extra step, now. Not an improvement, imo.). The Export options seem more robust, now, or maybe I didn't notice them before. But Export at 100% gives me a file size that's around 12mb for an image that's 4K.

Does that make sense? A 4K image yields a 12mb file size. The old Largest size Share option gave me a file size that was usually around 4MB.

So what was going on with the largest file option, before? Was I getting the best image I could, before, or is Export at 100% including a bunch of stuff I don't need?

Thanks for any help. I sense this might be why they took away the Largest size option under Share.

I believe that the old Largest Size option used a Quality setting of 80%. With Quality at 100% you'll get a larger file size. You won't always see the same amount of file size difference - how much larger the file is at higher quality settings depends on how much fine detail there is in the image.

Thank you, Laura. I makes sense the old Largest Size option was a lesser quality.

The „Largest Available Dimensions“ is still there in "Share to...“ together with the „Image Quality".
The „Export as..." gives you the additional possibility to export the original file type, i.e. a PNG picture.
Looks like Adobe should explain such changes next time via pop up messages.

And as a side thought, it might not be a bad idea for me to always share to social media at 80% or less, and keep the full rez offline.

Yes, 80% Image quality should be fine. When you google with keyword "social media best picture resolution" then you will find some pages with recommendations for the pixel dimensions :-)

There's a very good article on LR Classic JPEG Quality settings at the below link.

You'll need the below decoder to compare the 10 Quality settings in LR Desktop to LR Classic's 12 settings.

Summary: 80% in LR Mobile/Desktop is ok!
