Export and save
The last step is to take the RAW image currently in Lightroom and export it as a JPEG to your computer hard drive. To do this, go to File>Export to bring up the Export dialogue. Under Export Location, click Export To and choose Specific Folder. Now click on Choose to navigate to a place where you want to save your pic on your hard drive. Under File Settings, set Image Format to JPEG and Quality to 100 for maximum quality (or slightly less if you want to save on hard drive space). You can also tick Limit File Size To and enter a specific value to cap the file size for easy sharing online. Make sure Color Space is set to sRGB and hit Export to save your RAW. The finished JPEG will then appear in the folder of your choice.
