Why this program matters

Without Lottie, your GIF animations weigh up to 5 Mo, increasing load time by 40% and driving away 25% of mobile visitors according to Google.
Result: bounce rate skyrocketing to 70%, 30% loss in user engagement, and declining revenue because sites are perceived as slow.
Competitors using Lottie capture 2x more leads with fluid animations under 100 Ko.
Miss this training and stay stuck with outdated visuals that sabotage your digital ROI.
