For whatever reason, the Thunar file browser in XFCE does not automagically show thumbnails for webp images. Some searching produced a recipe, although the displayed webp.xml file needs the last two lines to close the tags:
<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
<mime-type type="image/webp">
<comment>WebP file</comment>
<icon name="image"/>
<glob-deleteall/>
<glob pattern="*.webp"/>
</mime-type>
</mime-info>
