Presently I am using winhttp api in c++ to get data from a server. The server can support various compression formats. So presently I want to use winhttp to get the compressed format (eg gzip) and decompress it. Is it possible to decompress the data using winhttp?

Surely it's possible.
From here:
To set the decoding option, the application calls InternetSetOption with the handle returned from InternetOpen, InternetConnect, or HttpOpenRequest. The INTERNET_OPTION_HTTP_DECODING option is specified in the dwOption parameter, and the lpBuffer parameter points to a boolean variable set to true. To disable decoding, the application calls InternetSetOption with the INTERNET_OPTION_HTTP_DECODING option and the boolean variable set to false.
So http compression is transprent for user code, you just need one call to InternetSetOption and your traffic will be compressed.
