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 AIFF output.
Format-Aware Presets
We tune FFmpeg flags so MP3 characteristics (color depth, metadata) persist when writing AIFF deliverables.
Ops-Level Observability
Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark MP3 → AIFF workflows.
