Frequently Asked Questions

What formats can I convert to?

You can convert to WAV (lossless), MP3 (compressed), or OGG (compressed). WAV is best for editing, MP3 for sharing, and OGG for open-source compatibility.

Does conversion reduce audio quality?

Converting to WAV maintains full quality. Converting to MP3 or OGG uses compression, but at 320 kbps the quality difference is minimal and barely noticeable.

What sample rate should I use?

44.1 kHz is CD quality and works for most uses. 48 kHz is professional standard for video. 96 kHz is high-resolution for audiophile use.

Is my audio uploaded to a server?

No! All audio processing happens locally in your browser using Web Audio API. Your files never leave your device.

Do I need to install any software?

No! ChangerAudio Audio Converter works entirely in your browser. No install, no download, no software required.
