in j2me canvas, how to reduce Image size?

I am doing project in j2me for Nokia s60 devices

This project has lo开发者_如何转开发t of PNG images and Sprite images there. All images are unique, so my project jar size is near 10MB. If I compress image, image does not look good, so I want to put actual image in this project.

in J2me Canvas, is there any image encoding to reduce size but keep good quality or not?
