When to Use Custom Progress Animations
Loading animations improve perceived performance and user experience:
Page Load States
Show progress while fetching data, loading images, or initializing apps. Reduces perceived wait time and keeps users engaged.
File Upload Progress
Display upload progress with branded animations. Linear and circular progress bars show percentage completion.
Mobile App Loaders
Lightweight animations perfect for React Native or Flutter apps. Small file size maintains fast app performance.
Form Submission
Show processing state after form submission. Assures users their action is being processed.
Dashboard Loading
Display while loading charts, analytics, or complex dashboard data. Professional appearance during data fetching.
Video/Media Loading
Show buffering states for video players or audio streaming. Better UX than generic browser loading indicators.
Progress Animation Best Practices
Get the most out of generated loading animations:
Match animation to load time
Use spinners for unknown durations, progress bars for measurable progress. Linear bars work best when you can show percentage.
Use brand colors consistently
Match your loading animations to your brand palette. Consistency builds trust and makes your app feel more polished.
Choose CSS for performance
CSS animations are lighter than Lottie (under 1KB). Use CSS export for simple loaders, Lottie for complex branded animations.
Adjust speed for context
Faster animations (1.5-2x) feel snappier for quick loads. Slower animations (0.5-1x) work better for longer wait times to avoid appearing frantic.

Frequently Asked Questions
Everything you need to know about Lottie animations and our tools.
What's the difference between Lottie and CSS export?
Lottie JSON offers advanced animation control, programmatic updates, and works with the lottie-web library. CSS export is pure CSS with no dependencies – just copy and paste into your stylesheet.
Are the generated loaders royalty-free?
Yes! All loaders you create are 100% royalty-free. Use them in personal or commercial projects without attribution. The generated code is yours to use however you like.
Which loader type should I use?
Spinner: Great for button loading states. Dots: Perfect for content loading. Linear: Ideal for file uploads. Circular: Best for progress percentages.
How do I use the Lottie JSON file?
Include lottie-web in your project, then use lottie.loadAnimation() with your JSON file. Works with React, Vue, Angular, and vanilla JavaScript.
Can I change the animation speed after export?
Yes! For Lottie, use anim.setSpeed(). For CSS, modify the animation-duration property. Both allow post-export customization.
Do the CSS loaders work in all browsers?
Yes! The generated CSS uses widely supported properties and works in Chrome, Firefox, Safari, Edge, and Opera. IE11 may show static fallback states.
How do I change colors in the dots loader?
Use the Primary color picker to set the dot color. The dots animate with opacity and scale transforms, so the base color stays consistent throughout the animation.
Can I create a loader with transparent background?
Absolutely! Both Lottie and CSS exports use transparent backgrounds by default. Preview with the checkerboard background to see how it will look over your content.
