To save a PNG image with Alpha, do the following:
- Change to Production Mode.
- Switch to the Channels Tab and check the Alpha Channel.
- After rendering the image, press the b button and select PNG Image+Alpha Files from the extensions drop-down.
Please note that the PNG Image+Alpha Files extension will not appear in case the Alpha Channel has not been enabled.
