When you call savefig(), you can pass "quality", "optimize" and
"progressive", as defined in the print_jpg docstring:
def print_jpg(self, filename_or_obj, *args, **kwargs):
"""
Supported kwargs:
*quality*: The image quality, on a scale from 1 (worst) to
95 (best). The default is 75. Values above 95 should
be avoided; 100 completely disables the JPEG
quantization stage.
*optimize*: If present, indicates that the encoder should
make an extra pass over the image in order to select
optimal encoder settings.
*progressive*: If present, indicates that this image
should be stored as a progressive JPEG file.
