Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. M4V binaries live inside WebAssembly memory and are disposed of immediately after producing a WebM output.
Format-Aware Presets
We tune FFmpeg flags so M4V 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 M4V → WebM workflows.
