Why teams trust this converter

Zero-Trust Ready

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

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

Ops-Level Observability

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