I think this is what you need

bitmap.compress(CompressFormat.JPEG, 90, outputStream);

I hope this will help you.

Good point. To those who don't know how to use this approach: 1. `ByteArrayOutputStream out = new ByteArrayOutputStream();` 2. `bitmap.compress(CompressFormat.JPEG, 90, out);` 3. write byte[] into file or use it anywhere else (for example you can show it in ImageView with the help of Glide lib) – Kirill Karmazin Oct 31 '18 at 21:27
