Large video and audio files can be optimized by:
1. Adaptive Bitrate Streaming
Serve multiple bitrate variants so users only download what their connection can handle.
2. Server‑Side Compression
Compress assets with modern codecs (e.g., AV1) before delivery.
3. CDN Caching
Cache frequently accessed files at edge nodes to reduce latency.
Implementing these steps can cut download times by up to 50 %.
