Why teams trust this converter

Zero-Trust Ready

Files never leave the tab. 3GP binaries live inside WebAssembly memory and are disposed of immediately after producing a MP3 output.

Format-Aware Presets

We tune FFmpeg flags so 3GP characteristics (color depth, metadata) persist when writing MP3 deliverables.

Ops-Level Observability

Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark 3GP → MP3 workflows.
