FAQ

Questions about
Audio Tools

Quick answers to what users ask before trying these tools.

Are my audio files uploaded?
No - every audio tool runs entirely client-side using the Web Audio API. Files never leave your device, no matter how large.
What is the max file size?
~500 MB per file practically (browser memory dependent). For full-length albums or long podcasts, batch process individual tracks.
Will I lose quality converting between formats?
MP3 → WAV is lossless (WAV is uncompressed). WAV → MP3 is lossy but at 256 kbps+ the difference is inaudible for most listeners.
Can I edit beyond trim?
Trim, volume, fade-in/out, and join are supported. For full DAW-style editing (multi-track, EQ), use Audacity or a real DAW.
Do the tools work with DRM'd files?
No - protected audio (Apple Music, Spotify, etc.) can't be decoded by web tools. We only work with files you own and have rights to.
