3. In the export window, choose the desired location to save the compressed file.
4. Below the “Format” dropdown menu, select “JPEG”.
5. Adjust the “Quality” slider to your desired level. Moving the slider to the left will decrease the file size but may result in a loss of image quality.
6. Click “Save” to save the compressed JPEG file.
