What is Online CSS Loader Generator?

CSS Loader Generator is a free online tool for generating CSS loaders. This tool is one of the best CSS loader animation generators in the web that consists hundreds of loaders and spinners. It also works as CSS spinner generator and CSS loading animation generator. CSS loaders are used to indicate users that a page, section, or element is not ready yet and there is a process in progress behind like data fetching or any other operation that takes some time. For better UX (user experience), it is advised to show CSS loading animations to users in such cases to prevent confusion whether a page or component works properly or not.


There are hundreds of CSS loaders from various categories such as CSS spinners, CSS progress loaders, dot, bar, shape, and colorful loaders, blobs, pulses, flipping and hypnotic loaders and many more. There are more than 250 CSS loading animations in total. All of them are customizable and no JavaScript is needed for making them work, in other words they are created with pure CSS. Sometimes, JS code may be used to animate, but it is better to use CSS-only loaders for better performance. You can customize the color, size, and speed of them just by selecting the option from a list. There is no need to know how to edit CSS code for customizing them at all.

Here you can see different types in the image below. Any shape from simple (like dot, bar, triangle, square, circle, line and so on) to complex (like wave, hearth, battery, watch and so on) can be used as a CSS loader if you are advanced enough to code it. Even their shapes and themes are different from each other, their purpose is the same.
