CSS Loader Library — Customize & Copy

The CSS Loader Library is a privacy-first collection of pure-CSS loading animations designed for developers and designers who want production-ready loaders without adding JavaScript dependencies. Use this library to browse and customize a wide range of patterns — spinners, pulsing dots, bar loaders, progress indicators, morphing blobs and more — then copy the minimal HTML and CSS into your project. Each preset is implemented with standard CSS keyframes and works in modern browsers; customize color, size and animation speed in the modal and preview changes live. For visual styling that pairs well with loaders, try our internal CSS Gradient Generator and Box Shadow Generator. For reference on animation behavior and cross-browser considerations, see the MDN docs on CSS animations: MDN — CSS Animations. This tool is ideal for prototyping, improving perceived performance during async tasks, or shipping consistent loading states across UI components.
