What is CSS Loader/Spinner Generator?

CSS Loader/Spinner Generator is a visual tool that helps you create beautiful loading animations using pure CSS. Instead of writing complex keyframe animations from scratch, simply browse through our collection of 43 handcrafted presets, customize them to match your design, and copy the code.

Why Use CSS Loaders?

Loading indicators are essential for user experience. They provide visual feedback during data fetching, page transitions, or any asynchronous operation. CSS-based loaders offer several advantages:

Lightweight

No JavaScript or image files required — pure CSS animations keep your bundle size minimal.

Customizable

Easy to change colors, sizes, and speeds to match your brand identity perfectly.

Performant

Hardware-accelerated CSS animations run smoothly across all devices without impacting performance.

Accessible

Works across all modern browsers with consistent rendering and no compatibility issues.

How to Use

Browse and Select a Loader

Use the category tabs (All, Spinner, Dots, Bars, Pulse, Progress, Shapes) to filter loaders by type. Each thumbnail shows a live animated preview. Click any loader to select it.

Quick tip: Click the Random button to discover new loaders quickly and get inspired.

Customize Your Loader

Once you've selected a loader, use the controls on the right to customize it:

Color — Click the color picker to choose any color for your loader
Size — Drag the slider or type a value between 20px and 120px
Speed — Adjust the animation duration from 0.3s (fast) to 3.0s (slow)

All changes are reflected in the live preview instantly.

Preview on Different Backgrounds

Toggle between Light, Dark, and Transparent backgrounds to see how your loader looks in different contexts. This helps ensure your loader is visible regardless of the page background.

Copy the Code

The code output section provides two tabs:

HTML — The markup structure for your loader
CSS — The complete styles with your customized values (color, size, speed already resolved)

Click the Copy button to copy the active tab's code to your clipboard. Paste the HTML into your page and add the CSS to your stylesheet.

Features

43 Curated Loader Presets

Every loader in our collection is carefully crafted for visual appeal and production readiness. From simple spinning rings to complex 3D cube animations, there's a loader for every use case.

All loaders use pure CSS with no JavaScript dependencies.

Real-Time Customization

Fine-tune every aspect of your loader with intuitive controls. Changes to color, size, and speed are applied instantly in the live preview.

No need to regenerate or refresh — see your changes immediately.

Background Preview Toggle

Preview your loader on light, dark, and transparent backgrounds to ensure it works well in any context.

The transparent checkerboard pattern helps you verify that your loader has no unexpected background artifacts.

Production-Ready Code Output

The generated CSS contains resolved values instead of variables. This means you get exact pixel sizes, specific colors, and precise timing values.

Ready to paste directly into your project without any additional setup.

Separate HTML and CSS: Code is split into dedicated HTML and CSS tabs, making it easy to copy each part to the right place in your project. The HTML provides minimal, semantic markup while the CSS handles all the visual styling and animation.

Frequently Asked Questions

Do the loaders require JavaScript?

No. All loaders are built with pure CSS animations and keyframes. You only need the HTML markup and CSS styles — no JavaScript is required for the animations to work.

Can I change the loader color after copying the code?

Yes. The generated CSS uses explicit color values (e.g., #6366f1). Simply find and replace the color value in the CSS to change it.

Pro tip: For easier theming, you can replace the color with a CSS custom property like var(--loader-color).

Are the loaders responsive?

The loaders use relative sizing based on the size value you set. You can adjust the size in the generator or modify the pixel values in the CSS to fit your layout. Using CSS custom properties makes it easy to create responsive loaders.

Which browsers support these loaders?

All loaders work in modern browsers including Chrome, Firefox, Safari, and Edge. They use standard CSS features like @keyframes, border-radius, and transform that are widely supported.

Can I use these loaders in commercial projects?

Yes. The generated CSS code is free to use in any project, including commercial ones. No attribution is required.

How do I make the loader appear during page load?

Add the loader HTML to your page and show it by default. When your content finishes loading, use JavaScript to hide or remove the loader element.

A common approach is to add a CSS class that fades out the loader with a transition:

Example Implementation

// Hide loader when page loads
window.addEventListener('load', function() {
    document.querySelector('.loader').classList.add('fade-out');
});
