How do animations and video affect website performance?

Last Updated: Nov 8, 20261 min read

Animations and video can make a site engaging, but they also add weight. Heavy autoplay videos, large animation libraries and unoptimised effects slow loading and hurt mobile users.

Use motion with purpose: to guide attention, show process or add polish. Keep files light, respect reduced-motion preferences and avoid blocking the main content.

Always test speed after adding effects and compare with your performance targets.

Keep motion efficient:

  • Compress video: short clips in modern formats
  • Lazy loading: load media when it appears
  • CSS animation: lighter than heavy scripts
  • Poster images: fast first view before playback
  • Reduced motion: respect user settings
  • Speed tests: measure before and after

Our logo design company in Dubai balances design ambition with speed, working with a ecommerce website development company in Dubai to optimise delivery.

Pro Tip

At Awrange, we replace autoplay hero videos with optimised images or short loops unless video is truly essential. The speed gain is usually worth it.
