When using HTTP, GCS decompresses gzip-encoded objects by default:
https://cloud.google.com/storage/docs/transcoding
``` Setting this option to `gzip` disables automatic decompression. This can be useful for applications wanting to operate with the compressed data. Setting this option to `identity`, or not setting this option, returns decompressed data.
<aside class="note"><b>Note:</b>
Note that decompressive transcoding only apply to objects that are compressed with `gzip` and have their `content_encoding()` attribute set accordingly. At the time of this writing GCS does not decompress objects stored with other compression algorithms, nor does it detect the object compression based on the object name or its contents.

[`AcceptEncodingGzip()`](xref:namespacegoogle_1_1cloud_1_1storage_1abb76cc18ed021b748ead4a4845b9b81e) is a helper function to disable decompressive encoding.
