Why teams trust this converter

Zero-Trust Ready

Files never leave the tab. MP3 binaries live inside WebAssembly memory and are disposed of immediately after producing a AVI output.

Format-Aware Presets

We tune FFmpeg flags so MP3 characteristics (color depth, metadata) persist when writing AVI deliverables.

Ops-Level Observability

Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark MP3 → AVI workflows.
