Variable fonts make it possible to animate typography without swapping font files or rendering text as images. This online Variable Font Animator changes OpenType variation axes such as weight, width, optical size, slant, and custom axes with CSS.

The first version runs fully in the browser. Choose a sample font, select an axis, tune motion settings, and copy the generated HTML and CSS. It is a lightweight frontend MVP intended for fast experimentation before deeper export workflows are connected.

  • Animate variable font axes directly in your browser.
  • Choose ready-made variable font samples and motion presets.
  • Tune the animated axis range, duration, stagger, and preview text.
  • Copy HTML and CSS for a frontend-only variable font animation.
