lottieloading-animationsuxreact

Loading states are often overlooked in UX, but a good spinner makes wait times feel intentional. A new curated list of free loading animations for web apps in 2025 organizes options by format, with Lottie as the gold standard due to small file sizes (5-30KB), resolution independence, and smooth performance. IconKing offers 500+ free Lottie animations including loading spinners, progress indicators, and transition animations, downloadable as JSON without an account. Developers can preview files at iconking.net/preview and customize colors to match their brand using the in-browser editor at iconking.net/editor. The article includes a React code snippet using lottie-web to integrate a Lottie loader, demonstrating how to load an animation from a JSON file. This resource saves developers time and effort in creating custom loading animations, improving app polish with minimal effort.

// why it matters
