Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. AIFF binaries live inside WebAssembly memory and are disposed of immediately after producing a MP3 output.
Format-Aware Presets
We tune FFmpeg flags so AIFF 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 AIFF → MP3 workflows.
