SVG vs Lottie: which animation format should you use?
SVG animation is best when motion is part of your interface and needs styling, accessibility or direct code control. Lottie is best when a designer exports a polished multi-layer animation that should play back as a reusable motion asset.
DOM-controlled SVG motion vs timeline animation data
SVG motion exposes shapes directly to CSS and JavaScript. Lottie packages a designed animation timeline into JSON that is played by a renderer.
Best when the animation should behave like part of the UI.
Best when polished motion is exported from a design animation workflow.
Best choice by animation workflow
This decision is less about image quality and more about ownership. Choose SVG when developers need direct control over interface motion. Choose Lottie when designers own a timeline animation and developers need to embed it reliably.
Choose SVG animation for
- Animated icons, loaders and stateful UI elements.
- Motion that must inherit theme colors or CSS variables.
- Interactive diagrams where individual parts need hover or click behavior.
- Small animation effects where adding a player would be unnecessary.
- Projects where the motion needs to remain readable and editable as markup.
Choose Lottie for
- Designer-created product illustrations exported from motion tools.
- Onboarding, empty-state or hero animations with many moving layers.
- Animations that need timeline playback, scrubbing or frame control.
- Teams where designers own the motion source and developers embed the result.
- Complex motion that would be hard to maintain as hand-written SVG/CSS.
SVG vs Lottie comparison table
| Decision point | SVG Animation | Lottie |
|---|---|---|
| Format model Best: Depends | Markup and elements SVG is an XML-based graphic where shapes, paths and styles remain directly available in the page. | JSON animation data Lottie is a JSON animation export, usually rendered by a player such as lottie-web. |
| Best animation type Best: Depends | UI-level motion Great for icon states, stroke drawing, simple loops, loaders and interactive interface effects. | Illustration motion Great for multi-layer product illustrations, character motion and designer-authored sequences. |
| Design handoff Best: Lottie | Developer-authored SVG motion is often built or refined in CSS and JavaScript after the graphic is prepared. | Designer-authored Lottie is usually exported from animation tools and preserves a timeline-style workflow. |
| Runtime dependency Best: SVG | No player required Basic SVG animation can run with browser features and your own CSS or JavaScript. | Player required Lottie needs a compatible renderer/player and support code in the page or app. |
| Interactivity Best: SVG | Direct DOM control Individual SVG elements can respond to hover, state, theme and application logic. | Timeline control Lottie can be played, paused and scrubbed, but editing individual layers at runtime is less direct. |
| File size Best: Depends | Tiny for simple motion Small shape-based effects can stay very compact after optimization. | Efficient for complex motion A detailed illustration may be smaller and easier to manage as Lottie than as hand-coded SVG motion. |
| Styling and theming Best: SVG | Easy to theme Inline SVG can inherit CSS variables, currentColor and design-system states. | More constrained Lottie colors can be changed, but the workflow is usually less natural than CSS styling. |
| Accessibility Best: SVG | Can be semantic SVG can include titles, descriptions and reduced-motion handling inside your UI flow. | Needs wrapper care Lottie often needs surrounding labels, pause controls and reduced-motion fallbacks. |
| Editing Best: Depends | Code-editable Paths, strokes, colors and timing can be adjusted directly in code. | Source-tool editable Real edits usually happen in the original animation project before exporting JSON again. |
| Best use Best: Depends | Interface components Use for icons, diagrams, loaders and small interactive SVG effects. | Product storytelling Use for onboarding animations, hero illustrations and polished motion sequences. |
Workflow and ownership
SVG animation works well when the animation is part of the interface system. Developers can style it, trigger it from state and keep the markup close to the component.
Lottie works well when a motion designer creates the animation in a timeline tool and exports a JSON asset. The developer embeds the player instead of rebuilding the motion by hand.
Runtime and dependencies
SVG can animate with browser-native CSS or JavaScript. For small effects, that usually means fewer moving parts and no extra animation runtime.
Lottie requires a renderer, but that tradeoff can be worth it for complex sequences that would otherwise be difficult to reproduce as maintainable code.
Accessibility and reduced motion
SVG can be labelled, hidden as decorative content, or paused with normal UI state patterns. It can also follow CSS reduced-motion preferences.
Lottie can be accessible too, but it needs surrounding semantics, pause behavior and reduced-motion decisions because the animation itself is delivered as playback data.
Editing and maintenance
SVG is easier to adjust when the change is simple: color, stroke, size, easing, state or a small transform.
Lottie is easier when the motion has many layers and keyframes. Real edits usually belong in the source design file before exporting a new JSON version.
Final recommendation
Use SVG animation for lightweight UI motion, interactive icons, loaders and diagrams that need direct code control. Use Lottie for polished product animations, onboarding scenes and complex motion designed in a dedicated animation workflow.
A practical rule is simple: treat SVG as component-level motion and Lottie as a packaged motion asset.
Prepare SVG motion assets
Clean and inspect SVG markup before turning it into interface motion or comparing it with animation exports.
