Is it possible to embed high-quality gifs into the CMS editor/on an article or blog post/

Like this, for example? A Taxonomy of Donald Trump’s Facial Expressions - The Atlantic

Hi @respublica, the built in asset panel/cms image allows you to upload gif files that have a maximum of 4mb.

You might be able to embed a gif also using custom html, learn more about using custom code: Custom code | Webflow University

I hope this helps
