I encoded it with the following settings.

In XnviewMP1.5.5,
This sample was able to convert 30 bytes.

In later versions, (in my case) I was able to encode with 34 bytes.

・ Is it possible to encode with 30 bytes even after XnviewMP1.5.5?

1. Extract cwebp from the latest libwebp-1.3.2-windows-x64.zip and

For genuine libwebp-1.3.2,
I was able to compress it to 30 bytes without any problems.

I sincerely hope this post will help you share your issue across forums and your issue will be resolved...
