Image compression without loss of quality

I am developing an Android application that takes pictures and saves it. And I want to make the download speed faster by compressing the image. But since I compressed them using BitmapCompress, the image seems to be lost in quality. Here:

COMPRESSED :

BEFORE : SIZE - 1920X1920 FILE SIZE - 2.94 MB

AFTER : SIZE - 960X960 FILE SIZE - 644 KB

I wonder if there is a way, maybe the library can solve my problem? Instagram seems to do this compression material without losing image quality.

OutputStream os = new FileOutputStream(filename); 
yourbitmap.compress(CompressFormat.JPEG, 80, os);  // 80% compression

This will keep your image and good quality.
