Will metadata (artist, album) be kept?

Depends on source and target formats; always spot-check tags after conversion.

Can I convert DRM-protected files?

No. Only content you have the right to process should be uploaded.

Clip sounds distorted?

Lower gain or choose a higher bitrate; clipping cannot be undone magically.

Audio converter: codecs, quality, and compatibility

Different players and platforms prefer different audio containers and codecs—MP3 for universal playback, AAC for streaming stacks, FLAC for archival, WAV for editing stems. Toolfex helps you move between formats while thinking about bitrate and sample rate tradeoffs.

Higher bitrates preserve detail but increase file size. Match settings to your audience: podcast listeners on mobile data benefit from smaller files; mastering archives should stay lossless.

Practical tips

Normalize loudness if clips come from different sources.
Keep lossless masters before creating lossy distributions.
Trim silence in a DAW when file size matters.
Verify mono vs stereo expectations for voice vs music.
