About this tool

Loading indicators reassure users that something is happening, and the lightest ones are pure CSS — no JavaScript, no image, just an animated element. This tool offers a gallery of CSS loaders — spinners, wave bars, bouncing dots, radar pulses and more — that you can customise for colour, size and animation speed, then copy as clean HTML and keyframe CSS.

Because they are pure CSS, these loaders add virtually no weight and run smoothly without blocking the main thread. Customising the colour to match your brand and the speed to feel right takes moments, and the output has zero dependencies, so it drops into any project.

It runs in your browser, so you can preview and tweak instantly. Use a loader for page transitions, data fetches, button busy-states and anywhere a short wait benefits from visible feedback.

Frequently asked questions

What kinds of loaders can I generate?
A range of pure-CSS indicators including spinners, wave bars, bouncing dots and radar pulses, each customisable for colour, size and speed.
Do these loaders use JavaScript?
No. They are pure CSS with keyframe animations, so they are lightweight and have no JavaScript dependencies.
Can I match a loader to my brand?
Yes. You can adjust the colour, size and animation speed, and the tool outputs the corresponding HTML and CSS to copy.
Are CSS loaders good for performance?
Generally yes — they add almost no weight and animate efficiently, avoiding the overhead of an animated image or a JavaScript loop.
Is it done in the browser?
Yes. Everything runs locally, so nothing is uploaded.
