 I import my jpgs from my Card reader into LR Classic. Make the adjustments I need then edit in Portrait Professional studio Max and back to LR when done . Then I Export my files to my desktop folder.
   Lets say my orig. jpg file size is 12mp and when I export from LR its about 7-8Mp
   I lost some of the file size. Is there something I am doing wrong?  Thank you

In the export dialogue box, in the file settings area check the quality setting and make sure it is at 100.  Also make sure you have not set a file size limit.

Do you mean Mp (megapixels) or Mb (megabite)?

If mp then you have resize checked in the export dialog.  If mb then as posted, the compression needs to be turned off.

To Rollsman,

Saving a jpg file after making some adjustments will inevitably cause some data loss, sometimes insignificant especially if you set the quality to 100, but data loss there will be. When you save your file in Portrait as a jpg the jpg algorithm will examine the file and compress it, trowing away data it considers unnecessary.

It appears that you are making portraits. Since you are already prepared to make adjustment in LR and in a portrait software you would be perhaps wise to use RAW files to begin with. Remember that a jpg file is a final product, just like a Polaroid print out of the camera. JPG have their uses of course, but your raw file is your original 'negative'.

For JPEGs, not really:
