Why teams trust this converter

Zero-Trust Ready

Files never leave the tab. AVI binaries live inside WebAssembly memory and are disposed of immediately after producing a WebM output.

Format-Aware Presets

We tune FFmpeg flags so AVI characteristics (color depth, metadata) persist when writing WEBM deliverables.

Ops-Level Observability

Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark AVI → WebM workflows.
