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 MP4 output.

Format-Aware Presets

We tune FFmpeg flags so M4V characteristics (color depth, metadata) persist when writing MP4 deliverables.

Ops-Level Observability

Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark M4V → MP4 workflows.
