Is it possible to reduce image size when shared

[wsistudio]

I understand you can make images available in lightroom cc using collections.  But I notice that this option uploads the full sized file to cc, thereby using up my limited cloud storage of 20gb, also also slows down the sync process.  I often use cc on a small screen tablet or phone.  Is there a way to upload lower resolution images to cc?  The images that I m making dealing with are all high res jpegs.

Please be more specific with your versions of the Lightroom Apps. (No Apps use the "CC" in the name now!)

"Is there a way to upload lower resolution images to cc?"

Lightroom-CLASSIC  will ALWAYS upload (Sync from Collections ) smaller Proxy (Smart Preview) files of reduced pixel dimensions (2560px long edge) to the Cloud ecosystem.  These Proxy files do not occupy any space at all in your 20Gb allocation.
