Going from compressed to uncompressed is lossless in most cases, but compressed to compressed is ALWAYS lossy. Even with an intermediary compressed -> uncompressed -> compressed theres usually a noticeable amount of loss.
You are saying that you use an extension to convert from WebP to PNG, right? PNG is a lossless file format. It’s compressed, but losslessly. Like zip is also lossless compression. You can remove information to make it more compressible and then it’s a lossy process, but that’s not because of PNG, but because of the specific workflow.

I said the conversion in this specific use case causes loss, it does. End of story.
