Check your input first. Most surprises come from code the Converter cannot turn into native Webflow elements, so it keeps that part working as an embed instead.
:root blocks go into a CSS Embed. So do rules the Webflow style panel cannot hold, such as :nth-child, :not and multi-level descendant selectors.<form> become embeds. Wrap them in one.Values such as clamp(), calc(), min(), max(), ch and fr units, backdrop-filter and background-image: url() are kept as raw values. Find them in the Custom Properties panel in Webflow.
Only max-width media queries map to Webflow breakpoints.
The result is one Section. Convert one section at a time, not a whole page.
Convert to Figma takes HTML and CSS only and keeps the static look. JavaScript is ignored.
You should see the output in the preview, with the node and style counts shown. Conversions are free, with no AI tokens.
If it did not work: simplify the code with class-only styling, then convert again. The writing guide has an example prompt.
