Generate animated loading spinners as SVG
A loading spinner reassures users that something is happening while they wait. This generator produces a self-contained animated SVG spinner: a faint full ring as a track, with a coloured arc that rotates continuously on top. You control the size, the stroke thickness, the two colours and the rotation speed in seconds. Because the animation is built in with a standard SVG animate element, the spinner moves on its own with no CSS or JavaScript required.
The arc is a partial stroke on a circle, rotated endlessly, which gives the familiar smooth spinning effect.
Using the spinner
A self-contained animated SVG is ideal for loading states because it works inline in HTML, as a standalone file, or even as an image in many contexts, all without extra scripts. The spinner stays crisp at any size and can be recoloured to match your interface. A faster speed signals urgency while a slower one feels calmer, so you can tune the feel to your design.
Everything is generated locally in your browser, and the output needs no external dependencies to animate.

Frequently Asked Questions
Does the spinner animate on its own?
Yes. The rotation is built in with a standard SVG animate element, so it spins without any CSS or JavaScript.
Can I change the speed?
Yes. The speed is set in seconds per rotation, so a smaller value spins faster and a larger value spins slower.
Where can I use it?
Inline in HTML, as a standalone SVG file, or anywhere animated SVG is supported, as a loading indicator.
Does it stay sharp at any size?
Yes. It is vector SVG, so it remains crisp whether it is a tiny inline spinner or a large one.
