Bitmap compress doesn't changing bitmap byte size

Question

I'm trying to reduce bitmap size by using compress method.

This is my code:

public Bitmap compressImage(Bitmap image) {
        Bitmap immagex = image;
        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        Log.i("before compress", immagex.getByteCount()+"");

        boolean compress = immagex.compress(Bitmap.CompressFormat.JPEG, 10, baos);

        if(compress)
            Log.i("after compress", immagex.getByteCount()+"");
        else
            Log.i("bad compress", "bad compress");

        return immagex;
    }

When i check my logs i get:

11-28 11:10:38.252: I/before compress(2429): 374544
11-28 11:10:38.262: I/after compress(2429): 374544

Why is the compress does not work?

UPDATE:

I tried this code:

public Bitmap compressImage(Bitmap image) {
        Bitmap immagex = image;
        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        Log.i("before compress", immagex.getByteCount()+"");

        boolean compress = immagex.compress(Bitmap.CompressFormat.JPEG, 10, baos);

        Log.i("after compress 2", decodeSampledBitmapFromByte(image.getWidth(), image.getHeight(), baos.toByteArray()).getByteCount()+"");

        return immagex;
    }

Still the same byte count

11-28 11:33:04.335: I/before compress(3472): 374544
11-28 11:33:04.395: I/after compress 2(3472): 374544

Following is the code for reducing the bitmap size and convert it to base64,

    Bitmap newBitmap = Bitmap.createScaledBitmap(bitmap, 50, 50, true);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    newBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] byteArray = baos.toByteArray();
    String imageEncoded = Base64.encodeToString(byteArray, Base64.DEFAULT);

    Log.e("Base 64 String", imageEncoded);
