Don't let this gap widen
Without Lottie, your GIF animations weigh down pages by an average of 5 MB, slowing loading by 3 seconds, increasing bounce rate by 32% according to Google Analytics.
Lose 25% of mobile conversions, as 53% of users abandon slow sites (Source: Google).
Competitors with smooth animations capture 40% more attention.
Avoid costly redesigns at 10k€, negative UX complaints, and tech lag compared to Airbnb or Spotify who integrate Lottie everywhere.
Train to boost engagement and Core Web Vitals SEO tomorrow.
Dive into the Lottie universe, explore its lightweight JSON format from Adobe After Effects, install Bodymovin, create your first simple animation with shapes and transitions, export it to JSON, test it online via LottieFiles, and analyze the lightweight advantages compared to GIFs, while completing guided exercises to master initial workflows.
Design complex animations with masks, particles, and animated text in After Effects, apply markers for interactions, export via Bodymovin with optimization, integrate dynamic colors, test on various devices via Lottie preview, and produce two ready-to-integrate deliverables, chaining practical exercises and live feedback to boost your creativity.
Implement Lottie on websites by importing the CDN player, code responsive animations with CSS, add play/pause controls via JS, synchronize with scroll and hover, test performance on Chrome DevTools, create a complete animated landing page as a deliverable, and optimize for smooth 60fps rendering, for immediate and engaging results.
Deploy Lottie in React Native via react-native-lottie, configure animations in Flutter with the lottie package, manage states and interactive loops, test on iOS/Android emulators, integrate into an app prototype with touch gestures, produce a functional multi-platform deliverable, and learn common pitfalls for seamless deployment.
Review Lottie JSON optimization tools, reduce file sizes by 50% without quality loss, add advanced interactions with DotLottie, deploy a personal capstone project with an animated portfolio, evaluate real performance, receive expert feedback, and leave with a complete toolkit, ready to impress in production.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
