It seems like there is no code samples for WebP in C#. Is there any? I don't need to display WebP images directly but saving & transferring as WebP would be nice.

Take a look at http://webp.codeplex.com/. There is a library that allows you to easily encode into WebP format. Check out this question for more information:

Convert Bitmap to WebP Image?

The library allows you to save into WebP format like so:

using (Image image = Image.FromFile("image.jpg"))
{
   Bitmap bitmap = new Bitmap(image);
   WebPFormat.SaveToFile("image.webp", bitmap);
}

WebP-wrapper

Wrapper for libwebp in C#. The most complete wapper in pure managed C#. Exposes Simple Decoding API, Simple Encoding API, Advanced Encoding API (with compresion statistics), Get library version and WebPGetFeatures (info of any WebP file). In the future I´ll update for expose Advanced Decoding API. The wrapper is in safe managed code in one class. No need for external dll except libwebp_x86.dll and libwebp_x64.dll (included v6.1). The wrapper work in 32, 64 bit or ANY (auto swith to the apropiate library).

The code is full comented and include simple example for using the wrapper.

I needed a way to convert .webp images to .jpg images and it works great. – Thermodynamics
It doesn't work, just throws exception during WebPGetFeatures WebPGetFeaturesInternal_x64, impossible to debug further because it's a dLL, moreover the error message simply gives the name of the DLL file! – Reeva
There is literally not a single example of anyone in the world trying to use this DLL in Unity C#. – Reeva

There is https://github.com/mc-kay/libwebp-sharp wrapper project. But it doesn't seem to be implemented.
