Re-size and Compress Image in Android Studio

Bitmap b = BitmapFactory.decodeFile("Pass your file path");
// original measurements
int origWidth = b.getWidth();
int origHeight = b.getHeight();

final int destWidth = 500;//or the width you need

if(origWidth > destWidth){
         // picture is wider than we want it, we calculate its target height
          int destHeight = origHeight/( origWidth / destWidth ) ;
         // we create an scaled bitmap so it reduces the image, not just trim it
          Bitmap b2 = Bitmap.createScaledBitmap(b, destWidth, destHeight, false);
          ByteArrayOutputStream outStream = new ByteArrayOutputStream();
            // compress to the format you want, JPEG, PNG... 
            // 70 is the 0-100 quality percentage
    b2.compress(Bitmap.CompressFormat.JPEG,70 , outStream);
            // we save the file, at least until we have made use of it
           File f = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "test.jpg");

    FileOutputStream fo = new FileOutputStream(f);
    fo.write(outStream.toByteArray());
