How to save an image on Android without compressing it?

I'm making an Android application that captures images and saves them in the internal memory, but when I save them the images are compressed and I want them to be saved in original size without any kind of understanding.

this is the code I'm using to save the images, how do I not compress them?

public File saveToInternalStorage(Context context, Bitmap bitmapImage) {
        ContextWrapper cw = new ContextWrapper(context);

        File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);

        File mypath = new File(directory, "TheChat" + (System.currentTimeMillis()/1000) + "Avatar.jpg");

        FileOutputStream fileOutputStream = null;
        try {
            fileOutputStream = new FileOutputStream(mypath);
            bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fileOutputStream);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        finally {
            try {
                if (fileOutputStream != null) {
                    fileOutputStream.flush();
                    fileOutputStream.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return mypath;
    }
