Photoshop Save for web does'nt retain transparency

Question

I have been trying to save for web from a psd file, The .PNG file that I get has no transparency and instead all transparent area is filled with white.

I am beginner in Photoshop, How can I accomplish this task?

Answer 1

Normally if you are doing save for web in png 8 format it will take white color instead of transparency to avoid this white color You have to do save for web as png 24 format then u will get transparency without white color

Answer 2

The Problem got Solved, the App/program i was using had some problem and was not showing the background to be transparent, have tried it on another program and its OK
