Web animation and motion design in Lyon — Bring your online presence to life

Motion design: much more than a visual effect

Animation and brand recall

Movement catches the eye before text does: it is an attention mechanism every designer knows. A logo animation, a smooth page transition or a micro-interaction on a button creates powerful memory anchors. Visitors remember your brand better when it is associated with movement. That is why the world's most memorable brands invest heavily in motion design. And it is no longer reserved for large companies — small businesses in Lyon can benefit from it too, at an accessible cost.

Animations that improve UX (and those that harm it)

Not all animations are equal. Animations that improve UX serve a functional purpose: guiding the eye, confirming an action, making content easier to understand or creating a logical transition between two states. Animations that harm UX slow the site down, distract the user, hide content or create unwanted surprises. At KAYZEN, every animation is assessed for its impact on user experience and technical performance.

Performance and animation: striking the right balance

Web animation is often blamed for slowing sites down. That is true when it is poorly implemented. At KAYZEN, we use only high-performance animation techniques: CSS transforms and opacity (GPU-accelerated), optimised Framer Motion animations, Lottie for complex animations and lazy loading to defer loading. The result: lively websites that keep excellent Core Web Vitals scores.

Our motion design and animation services

UI micro-interactions

Micro-interactions are the small animations that make your site feel alive and responsive: hover effects on buttons and links, visual feedback on form fields, smooth page transitions, custom loading indicators and scroll-triggered animations. Used with restraint, they convey quality and attention to detail, strengthening the positive perception of your brand.

Lottie animations for the web

Lottie animations are the standard of modern web animation. Created in After Effects and exported as JSON, they are 10 times lighter than a GIF and infinitely scalable (vector-based). Ideal for animated illustrations, interactive icons, animated infographics and custom loaders. We integrate them natively into your React sites for optimal performance.

Corporate videos and motion graphics

We produce professional motion design videos: company presentations (30 to 90 seconds), explainer videos for your services or products, logo animations for your video intros, and opening sequences for YouTube or social media content. Every video is scripted, storyboarded and produced in your visual identity. The finish is premium and suited to your distribution channels.

After Effects animations exported for the web

For projects that need complex animation (multi-layer parallax, morphing, 2D cinematics), we use After Effects for creation and Bodymovin/Lottie for web export. The result: animations with a fluidity and visual richness impossible to achieve with CSS alone, yet still light and fast on mobile.

Animated banners for Google Ads and social media

Animated banners capture five times more attention than static ones. We create HTML5 banners for your Google Display Ads campaigns and animated visuals for your sponsored posts on Instagram, Facebook and LinkedIn. Every banner meets the platform's technical guidelines and includes a clear call to action.

Animation and web performance

Native CSS animations — zero impact on load time

The most common CSS animations (colour transitions, scale, opacity, translate) run directly on the browser's GPU without any additional JavaScript library. It is the most efficient solution for basic micro-interactions. At KAYZEN, we systematically favour native CSS whenever the animation's complexity allows, and we only load animation libraries (Framer Motion, Lottie) when they bring real added value.

Lottie vs GIF vs MP4: which should you choose?

GIFs are heavy, limited to 256 colours and no longer suited to the modern web. MP4s are ideal for video but do not easily support interactivity or transparency. Lottie animations are the optimal solution for the web: vector-based (scalable without loss), ultra-light (a few KB), interactive (reacting to scroll or click) and compatible with all modern browsers. We recommend Lottie for 90% of web animation use cases.

GPU acceleration and mobile optimisation

All our animations use GPU acceleration through the CSS transform and opacity properties, which are composited on the GPU without triggering costly re-layouts or repaints. On mobile, we reduce animation complexity for low-powered devices and respect user preferences (prefers-reduced-motion) for accessibility. Your animations run smoothly on the latest iPhone as well as on an entry-level smartphone.

Integration with your visual identity

Every animation we create stays true to your brand identity. Colours, typefaces, graphic style — the animations extend and reinforce your visual world. If you do not yet have brand guidelines, we can create them as part of the project. Discover our visual identity design service in Lyon.

The animations blend naturally into the UX/UI design of your website and enrich the experience of your brochure website or online shop.
