SMIL injection

The tool marks the first renderable element as svgkit-smil-target and appends an animateTransform translate animation.

Boundary

This is a concrete SMIL starter, not a full animation editor. Timing, easing, repeat behavior, and target selection can be refined in the generated markup.

Motion lives in the file — SMIL or CSS keyframes on a timeline transform & opacity animate cheaply — keep node counts low Respect prefers-reduced-motion in the surrounding page.
SVG SMIL Editor builds on SMIL or CSS animation, so the motion lives in the file and runs wherever the SVG renders.

How the animation layer works

SVG SMIL Editor builds on standards-based SVG animation (SMIL or CSS), so the motion lives in the file itself and runs wherever the SVG renders.

Preview versus production

Preview the result in the browsers your audience uses. Animation support and timing behavior can differ slightly across engines.

Performance notes

Animating transform and opacity is cheap; animating attributes that trigger layout or repainting entire paths is not. Keep node counts low for smooth motion.

Respecting reduced motion

Consider honoring prefers-reduced-motion in the surrounding page so the animation does not fight an accessibility setting.

How to use

  1. Paste SVG. Paste SVG markup.
  2. Insert SMIL. The tool adds animateTransform markup to the first renderable element.
  3. Copy SVG. Adjust timing or values in the generated SVG as needed.

Frequently asked questions

Which element gets animated?
The first renderable element in the SVG.
What animation is added?
A repeating translate animateTransform with a two-second duration.
Is SMIL supported everywhere?
Modern browsers generally support common SVG animation elements, but production compatibility should be checked for target environments.
Is SVG SMIL Editor free?
Yes. SVGKit tools are free to use with no account required.
Does SVG SMIL Editor upload my files?
No. The tool runs entirely in your browser, so your files never leave your device.
Where does the animation run?
In the SVG file itself — no JavaScript runtime from SVGKit ships with the output.
Which browsers support it?
Modern desktop and mobile browsers render SVG animation; very old engines vary. Test where it matters.
Why is my animation janky?
Usually too many animated elements or animating expensive properties. Reduce the node count or switch to transform-based motion.
