  There is no type for byte in protobuff 2 and 3.

  you will have to use int32, there is no "byte".

Are you just looking for bytes? It's listed under the Scalar Value Types in the docs. It's typically used to store a variable length number of bytes, so not sure on the efficiency of using it to store a single byte.

The type uint32 uses a variable length encoding, so that's probably the most efficient thing you can do.

If you look at how integers are encoded in the docs here you'll see that using an int32 is likely your best bet.

  @zheyiyi then as noted by Prasath and Dylan you will need to use something else, there is no single byte option.

  @zheyiyi updated answer, the int* types (except for fixedint) are variable length encoded so that is probably your best bet.
