Why client-side AVI media compression keeps your content private

ezyZip compresses AVI media using a full WebAssembly-compiled codec library running locally in your browser. Here is why local media compression is technically superior:

  • Local Codec ExecutionCompiled codec libraries run locally on your CPU, delivering the same encoding quality as desktop transcoding software. The WASM build includes optimized codec implementations that produce professional-grade output.
  • Multiple Compression StrategiesChoose between target file size, percentage reduction, or resolution scaling — each mode uses a different optimization strategy tailored to that compression goal, with adaptive algorithms that adjust parameters for your specific content.
  • Dual-Mode CompatibilityMulti-threaded primary execution via SharedArrayBuffer with automatic single-threaded fallback ensures consistent performance across all modern browsers. The engine detects your browser's capabilities and selects the optimal execution mode automatically.
  • No Restrictions or WatermarksThere are no file size limits, no watermarks stamped on output, no daily processing caps, and no queue wait times. You get unrestricted access to the full codec library with no artificial limitations.
