just wandering, how reduce file size of image keeping quality in c# .net?

i have following code use save image taken ipad:

the image been saved on 14mb. anyway can keep image quality , reduce file size below 2mb?

i don't think reduction without decresing picture quality possible. can remove metadata image using exif library without reducing picture quality

or if reduction in picture quality can use gid
