increasing dpi in export snapshot

[Durgesh Mishra]

I am using export snapshot on group of text boxes and saving it to a JPG
file. Looking at the resulting JPEG file, it does not look very smooth. It
is pixelized as if some low resolution image.

Is there any way to increase the dpi or some other mechanism to enhance the
image file generated from export snapshot ?

Thank you all in advance,
Kind Regards,
