Yeah, but that's not a valid call format. As the doc string says
---
If IMAGE-FORMAT is non-nil, IMAGE is a string containing the
image data, and IMAGE-FORMAT is a symbol with a MIME format name
like "image/webp".
---
So you have to say
(image-convert "data" 'image/webp)
I'll rephrase the doc string, because it's not very well-written.
